[0060] In actual applications, the virtual device is configured to realize the specific device function on the chip, so as to reduce the number of devices, and the flexibility of use can be improved in the case of multiple paths and multiple types of devices. In order to further effectively reduce device redundancy, an embodiment of the present application provides a mixed virtual device, which improves the device scalability and efficiently uses the function modules.

[0061] Referring to Figure 1 , a step flowchart of a mixed virtual device construction method provided in an embodiment of the present application is shown, which can specifically include the following steps:

[0062] Step 101, determining a data source type, and determining a starting point input and output module based on the data source type;

[0063] Step 102, determining a function module;

[0064] Step 103, determining an output data type, and determining an ending point input and output module based on the output data type;

[0065] Step 104, generating a plurality of independent virtual devices by using the starting point input and output module, the function module and the ending point input and output module;

[0066] Step 105, constructing a mixed virtual device by using a plurality of the independent virtual devices.

[0067] The hybrid virtual device can be composed of multiple independent virtual devices, and therefore, in order to construct the hybrid virtual device, the embodiment of the present application can first generate the independent virtual device.

[0068] GPIO (General-purpose input / output) is a general-purpose input / output, which is similar to P0-P3 of 8051, and the pin thereof can be freely used by a user through program control, and the PIN can be used as a general-purpose input (GPI) or a general-purpose output (GPO) or a general-purpose input and output (GPIO) according to actual conditions, such as clk generator and chip select.

[0069] Direct Memory Access (DMA) is a function provided by some computer bus architectures, which can enable data to be directly sent from an additional device (such as a disk drive) to the memory of a computer mainboard.

[0070] Reference Figure 2 , Figure 2 is a structural schematic diagram of an independent virtual device provided in the embodiment of the present application, the independent virtual device of the embodiment of the present application can be composed of a start input / output module, one or more function modules, and an end input / output module, wherein the first function module closest to the start input / output module, the second function module next to the start input / output module, and so on, the embodiment of the present application can combine multiple function modules in a data flow pipeline manner to construct multiple independent virtual devices, and optionally, different virtual devices can use the same function module, for example, two virtual devices both need to perform encryption and decryption operations on input / output data, at this time, the two virtual devices can share the same encryption and decryption function module in different time periods, wherein the start and end of the flow are input / output modules, such as a GPIO chip pin input / output module and a DMA memory input / output module, and the data flow direction between the function modules can be unidirectional or bidirectional.

[0071] After the structure of the independent virtual device is determined, the independent virtual device can be generated based on the structure.

[0072] In a specific implementation, the embodiment of the present application can determine the data source type, determine the start input / output module based on the data source type, determine the function module according to actual business requirements, determine the output data type, and determine the end input / output module based on the output data type, so as to determine the independent virtual device through the start input / output module, the function module, and the end input / output module, and the hybrid virtual device can be constructed through multiple independent virtual devices.

[0073] Exemplarily, reference is made to Figure 3 , Figure 3Fig. 1 is a flowchart of a process for user registration of a virtual device according to an embodiment of the present application.

[0074] The user applies for a virtual device number to the virtual device manager, and the virtual device manager reserves a virtual device identifier for the virtual device in the virtual device pipeline configuration table;

[0075] Static Random-Access Memory (SRAM) is a type of random-access memory. The so-called "static" means that as long as the power is kept on, the data stored in the memory can be constantly maintained. In contrast, the data stored in dynamic random access memory (DRAM) needs to be updated periodically. However, when the power supply stops, the data stored in SRAM will also disappear (referred to as volatile memory), which is different from ROM or flash memory that can still store data after power off.

[0076] The start input / output module is used to sample the data source, so it can also be regarded as a data source module. The user can determine the virtual device data source module in the following way:

[0077] If the source data is sampled from the chip pin through GPIO, that is, the data source type is GPIO data, then the chip pin input / output module is used as the start input / output module.

[0078] If the source data is obtained from the system SRAM, that is, the data source type is SRAM data, then the DMA memory input / output module is used as the start input / output module.

[0079] The function module can also be regarded as an intermediate node module. The function module can be determined according to actual business requirements, for example, a decryption and encryption data processing module for performing decryption and encryption operations on data.

[0080] The end input / output module can be used for data output, so it can also be regarded as a data sink module. The user can determine the data sink module in the following way:

[0081] If the data is output from the chip pin through GPIO, that is, the output data type is GPIO data, then the chip pin input / output module can be used as the end input / output module.

[0082] If the source data is obtained from the system SRAM, that is, the data source type is SRAM data, then the DMA memory input / output module is used as the end input / output module.

[0083] In an alternative embodiment of the present application, when there is no data sink module, the hybrid virtual device can be configured on a processor, such as a central processing unit (CPU) or the like, and the processor can be configured with an IO bus, and the processor can take output data from a state parameter table of the last stage functional module of the independent virtual device through the IO bus.

[0084] After the construction of the hybrid virtual device is completed, the hybrid virtual device can be started, and at this time, the hybrid virtual device will process input data obtained from the data source module stage by stage under the scheduling of the virtual device manager, and place the result in the input data buffer memory of the data sink module, and send an interrupt signal to the processor according to the user configuration.

[0085] Of course, the above examples are only examples, for example, a person skilled in the art can replace manual selection with preset rule code according to the present application, and the present application is not limited thereto.

[0086] In the embodiment of the present application, the type of the data source is determined, and the starting point input / output module is determined based on the type of the data source; the functional module is determined; the type of the output data is determined, and the terminal point input / output module is determined based on the type of the output data; the starting point input / output module, the functional module and the terminal point input / output module are used to generate a plurality of independent virtual devices; and the plurality of independent virtual devices are used to construct a hybrid virtual device, so that the virtual device realizes the specific device function on the chip, and the device redundancy is reduced.

[0087] On the basis of the above embodiment, a variant embodiment of the above embodiment is proposed, and it should be noted that, in order to make the description brief, only the differences from the above embodiment are described in the variant embodiment.

[0088] In an alternative embodiment of the present application, it further comprises:

[0089] The data source module configuration parameter table, the intermediate node module configuration parameter table and the data sink module configuration parameter table for the independent virtual device are constructed;

[0090] The data source module configuration parameter for the starting point input / output module is determined, and the data source module configuration parameter is written into the data source module configuration parameter table;

[0091] When the functional module is an external device module, the intermediate node module configuration parameter for expressing the input / output data format of the functional module is determined, and the intermediate node module configuration parameter is written into the intermediate node module configuration parameter table;

[0092] The data sink module configuration parameter for the starting point input / output module is determined, and the data sink module configuration parameter is written into the data sink module configuration parameter table;

[0093] starting the mixed virtual device.

[0094] Exemplarily, refer to Figure 3 , Figure 3 is a flow diagram of user registration of a virtual device provided in an embodiment of the present application.

[0095] The user applies for a virtual device number to the virtual device manager, and the virtual device manager reserves a virtual device identifier for the virtual device in a virtual device pipeline configuration table;

[0096] The start input / output module is used for sampling a data source, and can also be regarded as a data source module. The user can configure the virtual device data source module in the following manner:

[0097] The data source module configuration parameter table, the intermediate node module configuration parameter table and the data sink module configuration parameter table for the independent virtual device are constructed;

[0098] If the source data is obtained by sampling from a chip pin through GPIO, that is, the data source type is GPIO data, the chip pin input / output module is used as the start input / output module, and the sampling clock source, clock frequency, filtering coefficient and other data source module configuration parameters are written into the data source module configuration parameter table for the virtual device;

[0099] If the source data is obtained from a system SRAM, that is, the data source type is SRAM data, the DMA memory input / output module is used as the start input / output module, and the data input address, length, buffer threshold, interrupt and other data source module configuration parameters are written into the source module configuration parameter table for the virtual device, and the first-level function module node of the virtual device identifier of the virtual device is inserted into the virtual device pipeline configuration table.

[0100] The full name of SPI is Serial Peripheral Interface, which means serial peripheral interface. SPI is a synchronous serial communication interface specification, mainly applied to short-distance communication in embedded systems.

[0101] The universal asynchronous receiver / transmitter (Universal Asynchronous Receiver / Transmitter, commonly referred to as UART) is an asynchronous receiver / transmitter, which is a part of computer hardware for transmitting data through serial communication. It performs parallel-to-serial data conversion at the sending end and serial-to-parallel data conversion at the receiving end. It is universal because the transmission speed, data speed and other parameters are configurable. UART is usually used in connection with other communication interfaces (such as EIARS-232).

[0102] I2C bus is a simple, bidirectional two-wire synchronous serial bus. It only needs two lines to transmit information between devices connected to the bus. The master device is used to start the bus to transmit data, and generates a clock to open the transmitting device, at this time any addressed device is considered as a slave device. The relationship between master and slave, sender and receiver on the bus is not constant, but depends on the direction of data transmission at this time. If the host wants to send data to the slave device, the host first addresses the slave device, then actively sends data to the slave device, and finally terminates the data transmission by the host; if the host wants to receive data from the slave device, the host first addresses the slave device. Then the host receives the data sent by the slave device, and finally terminates the receiving process by the host. In this case, the host is responsible for generating the timing clock and terminating the data transmission.

[0103] The function module can also be regarded as an intermediate node module, and the function module can be determined according to actual business requirements, for example, a data encryption and decryption processing module for performing encryption and decryption operations on data; the user can configure the function module in the following manner: if the function module is an SPI / UART / I2C peripheral module, the intermediate node module configuration parameters for expressing the input and output data format of the function module can be configured, for example, the byte format of I2C, the address format of bits, etc. can be used as intermediate node module configuration parameters, and written into the intermediate node module configuration parameter table of the virtual device, and the function module identifier of the virtual device is inserted into the virtual device pipeline configuration table.

[0104] The terminal input and output module can be used for data output, so it can also be regarded as a data sink module. The user can configure the data sink module in the following manner:

[0105] If the data is output from the chip pin through the GPIO, that is, the output data type is data for GPIO, the chip pin input and output module can be used as the terminal input and output module; and the output clock source, clock frequency and other data sink module configuration parameters are written into the data sink module configuration parameter table of the virtual device;

[0106] If the source data is obtained from the system SRAM, that is, the data source type is data for SRAM, the DMA memory input and output module is used as the terminal input and output module, and the data output address, length, buffer threshold, interrupt and other data sink module configuration parameters are written into the data sink module configuration parameter table of the data sink module.

[0107] In an optional embodiment of the present application, when there is no data sink module, the hybrid virtual device can be configured on a processor, such as a central processing unit CPU, etc. The processor can be configured with an IO bus, and the processor can take output data from the state parameter table of the last stage function module of the independent virtual device through the IO bus.

[0108] After the construction of the hybrid virtual device is completed, the hybrid virtual device can be started, at which time the hybrid virtual device will process the input data obtained from the data source module in stages under the scheduling of the virtual device manager, and place the results in the input data buffer memory of the data sink module, and send an interrupt signal to the processor according to the user configuration.

[0109] In an optional embodiment of the present application, the hybrid virtual device is provided with a bus arbiter, the independent virtual device is provided with a corresponding device identifier, and the functional module is provided with a corresponding input data buffer memory, and the present application further comprises:

[0110] When input data for a target virtual device is monitored, target data source module configuration parameters corresponding to the target virtual device are read from the data source module configuration parameter table according to a target device identifier corresponding to the target virtual device;

[0111] A target functional module corresponding to the target virtual device is determined based on the target device identifier;

[0112] The input data are obtained based on the target data source module configuration parameters;

[0113] The input data are stored in the target input data buffer memory corresponding to the target functional module through the bus arbiter.

[0114] Optionally, the functional module is provided with an input port and an output port, and the functional module is connected with the input data buffer memory through the input port and the output port.

[0115] Reference Figure 4 , Figure 4 is a structural schematic diagram of a functional module provided in an embodiment of the present application; a plurality of functional modules and a plurality of input data buffer memories can be in a one-to-one correspondence, the input port and the output port of the plurality of functional modules are connected with the plurality of input data buffer memories or registers to form a data exchange matrix, data are transmitted in a byte stream or bit stream mode, data in the data buffer area are stored in a mixed manner, and data packets of a plurality of virtual devices enter the buffer area in a sequential order, and a virtual device identifier is used as a guide code for the data packets of the input data.

[0116] In a specific implementation, the bus arbiter can be a device used to determine which data is preferentially processed by a module when multiple data are directed to the module, each independent virtual device can be configured with a bit-unique device identifier, and it can be understood that the target device identifier can be an identifier used to mark the target virtual device. When input data directed to the target virtual device is monitored, the target data source module configuration parameter corresponding to the target virtual device can be read from the data source module configuration parameter table according to the target device identifier corresponding to the target virtual device. The target data source module configuration parameter can be used to sample the data source. The target device identifier can also be used to determine the target function module corresponding to the target virtual device, that is, the function module needed by the target virtual device when processing actual services. Then, the bus arbiter stores the input data to the target input data buffer memory corresponding to the target function module.

[0117] In the embodiment of the application, the mixed virtual device input and output data buffer management is implemented. The input and output ports of the multiple function modules of the device and the multiple data buffer static memories or registers form a data exchange matrix. Data is transmitted in a byte stream or bit stream manner. The data packets of different virtual devices are mixed and stored, and are identified and distinguished by a packet preposition device identifier.

[0118] In an optional embodiment of the application, the method further comprises:

[0119] Obtaining a state parameter of the target input data buffer memory;

[0120] When it is determined based on the state parameter that the storage amount of the target input data buffer memory exceeds a first preset threshold, the target function module is up-regulated to a first frequency by using a first frequency multiplication coefficient.

[0121] When it is determined based on the state parameter that the storage amount of the target input data buffer memory exceeds a second preset threshold, the target function module is up-regulated to a second frequency by using a second frequency multiplication coefficient.

[0122] The second frequency is higher than the first frequency.

[0123] When it is determined based on the state parameter that the storage amount of the target input data buffer memory exceeds a third preset threshold, the target function module is up-regulated to a highest frequency by using a third frequency multiplication coefficient.

[0124] In actual application, the frequency multiplication coefficient refers to the relative proportional relationship between the CPU main frequency and the external frequency.

[0125] Reference Figure 5 , Figure 5is a function module storage threshold and frequency level relationship schematic diagram provided in the embodiment of the present application, the embodiment of the present application can adjust the running frequency of each function module according to the speed of the input data of the input data buffer memory corresponding to the function module, adopts a three-level threshold mechanism, when the input buffer data of the function module grows to the first preset threshold, adopts a first frequency multiplication coefficient, grows to the second preset threshold, adopts a second frequency multiplication coefficient, grows to the third preset threshold, uses the highest running frequency, when reduces to the next level threshold, uniformly adopts a frequency division coefficient of two until the lowest threshold.

[0126] Specifically, the hybrid virtual device can be configured with a virtual device manager, which can be a management system for the hybrid virtual device, the state parameters of the target input data buffer memory are obtained through the virtual device manager, and the state of each function module input data buffer is monitored based on the state parameters to prevent overflow and data loss;

[0127] When the target function module input buffer data grows to the first preset threshold, the virtual device manager adopts a first frequency multiplication coefficient to increase the target function module to the first frequency, until the data of the target input data buffer memory no longer grows;

[0128] When the target function module input buffer data grows to the second preset threshold, the virtual device manager adopts a second frequency multiplication coefficient to increase the target function module to the second frequency, until the data of the target input data buffer memory no longer grows;

[0129] S54: When the target function module input buffer data grows to the third preset threshold, the virtual device manager adopts a third frequency multiplication coefficient to increase the target function module to the third frequency, until the data of the target input data buffer memory produces overflow;

[0130] In an optional embodiment of the present application, when the target function module input buffer data decreases, the virtual device manager can adopt a frequency division coefficient of the target function module to reduce the frequency, until the data of the target input data buffer memory no longer decreases or reaches the lowest threshold or has reached the lowest running frequency of the target function module.

[0131] The embodiment of the present application acquires the state parameter of the target input data buffer memory, adopts a first frequency multiplication coefficient to up-regulate the target function module to a first frequency when determining that the storage amount of the target input data buffer memory exceeds a first preset threshold based on the state parameter, adopts a second frequency multiplication coefficient to up-regulate the target function module to a second frequency when determining that the storage amount of the target input data buffer memory exceeds a second preset threshold based on the state parameter, wherein the second frequency is higher than the first frequency, and adopts a third frequency multiplication coefficient to up-regulate the target function module to a highest frequency when determining that the storage amount of the target input data buffer memory exceeds a third preset threshold based on the state parameter, so that the virtual device manager can adaptively adjust the running frequency of each function module according to the speed of the input data of each function module, to balance the power consumption and throughput.

[0132] In an optional embodiment of the present application, the target function module is configured with a corresponding pipeline configuration table, which comprises:

[0133] When the target function module processes the input data, an output request information is sent to the bus arbiter, wherein the output request information at least comprises the target device identifier and the output packet length information.

[0134] The bus arbiter determines the next-level function module identifier of the next-level function module corresponding to the target function module in the pipeline configuration table according to the target device identifier and the target function module identifier of the currently requested target function module, wherein the next-level function module has a corresponding to-be-processed data sequence, and the to-be-processed data sequence is used to express the input data order to be processed by the target function module, and the input data has a corresponding priority identifier.

[0135] The bus arbiter encodes the input data into the to-be-processed data sequence according to the priority identifier.

[0136] The bus arbiter stores the input data into the next-level input data buffer memory corresponding to the next-level function module based on the to-be-processed data sequence.

[0137] Reference Figure 6 , Figure 6 is a structural schematic diagram of a bus arbiter provided in the embodiment of the present application;

[0138] In a specific implementation, the embodiment of the present application implements the virtual device manager by using a data exchange matrix and a bus arbiter, the bus arbiter references the virtual device pipeline configuration information of each virtual device, and according to the virtual device identifier, the device priority and the function module identifier of the currently requested output, the output data is guided into the input buffer of the next-level function module of the pipeline.

[0139] When the target function module finishes processing the input data, an output request information can be sent to the bus arbiter; the output request information at least includes the target device identification and the output packet length information of the data packet for the input data, the bus arbiter can find the next level function module identification of the next level function module corresponding to the target function module in the pipeline configuration table according to the target device identification and the target function module identification of the current requested target function module, the next level function module can be configured with a to-be-processed data sequence for expressing the order of the input data to be processed by the target function module, the input data has a corresponding priority identification, the bus arbiter can encode the input data into the to-be-processed data sequence according to the priority identification, and finally the input data is stored to the next level input data buffer memory corresponding to the next level function module through the bus arbiter based on the to-be-processed data sequence.

[0140] For example, when multiple independent virtual devices simultaneously apply for output to the same next level function module to the bus arbiter for data processing, the data of the multiple independent virtual devices will be arranged into a to-be-processed data sequence, and the input data with high priority can be arranged before the input data with low priority and is preferentially processed by the next level function module.

[0141] In the embodiment of the application, each function module can be specified by software with an input data buffer memory, the data bus arbiter transmits the output data of one function module to the input data buffer memory of the next function module through the data exchange matrix according to the configuration of each virtual device, and preferentially processes the data of the high-speed virtual device according to the priority specified by the user, so as to realize the scheduling running mode of the function module with high throughput and low delay.

[0142] In an optional embodiment of the application, the function module is configured with a corresponding state machine, and further comprises:

[0143] determining whether the input data buffer memory is empty;

[0144] If it is determined that the input data buffer memory is not empty, the state machine is reset.

[0145] In practical applications, the state machine refers to a finite state machine (English: finite-state machine, abbreviation: FSM) or a finite state automaton (English: finite-state automaton, abbreviation: FSA), which is a mathematical calculation model for representing a finite number of states and transitions and actions between these states.

[0146] Reference Figure 7 , Figure 7Is a reset flowchart for state machine provided in the embodiment of the application, before storing the input data to the target input data buffer memory corresponding to the target function module through the bus arbiter, whether the input data buffer memory is empty can be judged; if it is judged that the input data buffer memory is not empty, the state machine is reset to complete the initialization of the state machine.

[0147] In order to make the skilled in the art better understand the embodiments of the application, the following uses a complete example to explain the embodiments of the application.

[0148] As Figure 2 The data flow line method is used to combine a plurality of function modules to form a plurality of hybrid virtual devices, different virtual devices can use the same function module (such as two virtual devices need to encrypt and decrypt the input and output data, and can share the same encryption and decryption function module), wherein the starting point and the end point of the flow are input and output modules, such as GPIO chip pin input and output module and DMA memory input and output module, wherein the data flow between the function modules can be unidirectional or bidirectional;

[0149] As Figure 3 The input port and the output port of the plurality of function modules and the plurality of data buffer static memories or registers form a data exchange matrix, the data is transmitted in byte stream or bit stream mode, the data in the data buffer is mixed in storage mode, the data packets of the plurality of virtual devices enter the buffer in order, and the virtual device identifier is used as the packet guide code;

[0150] As Figure 7 The mixed virtual device switching is performed according to the device identifier in the input data, including four steps of resetting the module and reading the next data packet, loading the configuration parameters according to the virtual device identifier, loading the state parameters according to the virtual device identifier, and starting the function module to process the device data;

[0151] As Figure 6 The data exchange matrix and the bus arbiter are used to realize the virtual device manager, the bus arbiter references the pipeline configuration information of each virtual device, according to the device identifier, the device priority and the function module identifier of the current request output, the output data is guided into the input buffer of the next function module in the pipeline;

[0152] As Figure 5 According to the speed of the input data of each function module, the running frequency of the function module is adjusted, a three-level threshold mechanism is used, when the input buffer data of the function module increases to the first threshold, a first frequency multiplication coefficient is used, when the input buffer data increases to the second threshold, a second frequency multiplication coefficient is used, when the input buffer data increases to the third threshold, the highest running frequency is used, when it decreases to the next threshold, a halving frequency reduction coefficient is used until the lowest threshold.

[0153] As Figure 3 shown, the mixed virtual device configuration data pipeline can be implemented in the following way:

[0154] The user applies for a virtual device identification to the virtual device manager, which will reserve the virtual device identification in the virtual device pipeline configuration table;

[0155] The user configures the virtual device data source module:

[0156] If the source data is obtained by sampling from the chip pin through GPIO, the chip pin input and output module is used, and the sampling clock source, clock frequency, filtering coefficient and other configuration parameters are written into the configuration parameter table of the data source module of the virtual device;

[0157] If the source data is obtained from the system SRAM, the DMA memory input and output module is used, and the data input address, length, buffer threshold, interrupt and other configuration parameters are written into the configuration parameter table of the data source module of the virtual device, and the first level function module node of the virtual device identification is inserted into the virtual device pipeline configuration table;

[0158] The user configures the virtual device intermediate node module parameters:

[0159] If it is an SPI / UART / I2C peripheral module, the input and output data format and other parameters are configured and written into the node module configuration parameter table of the virtual device, and the function module identification of the virtual device is inserted into the virtual device pipeline configuration table;

[0160] The user configures the data sink module parameters:

[0161] If the data is output from the chip pin through GPIO, the chip pin input and output module is used, and the output clock source, clock frequency and other configuration parameters are written into the configuration parameter table of the data sink module of the virtual device;

[0162] If the data is output to the system SRAM, the DMA memory input and output module is used, and the data output address, length, buffer threshold, interrupt and other configuration parameters are written into the configuration parameter table of the data sink module; At the same time, the last level function module node of the virtual device identification is inserted into the virtual device pipeline configuration table; There can be no data sink module, at which time the processor will directly take the data from the state parameter table of the last level function module in the virtual device through the IO bus;

[0163] Start the virtual device, at which time the virtual device will process the input data obtained from the source data module step by step under the scheduling of the virtual device manager, and place the result in the input buffer of the data sink module, and send an interrupt to the processor according to the user configuration.

[0164] As shown in Figure 7 , the function module performs device switching can be performed by the following way:

[0165] When determining that the input data buffer memory of the function module is not empty, the function module state machine is reset, and the data packet is read in, the function module reads the configuration parameters of the virtual device at this level from the configuration parameter table according to the virtual device identifier;

[0166] The function module reads the state parameters of the virtual device at this level from the state parameter table according to the virtual device identifier;

[0167] The function module starts processing the data packet, and sends the result to the bus arbiter, which is transmitted to the input data buffer of the next level module.

[0168] As shown in Figure 5 , the virtual device manager performs adaptive frequency switching on the function module can be implemented by the following way:

[0169] The virtual device manager monitors the state of each function module input data buffer to prevent data loss caused by overflow;

[0170] When the function module input buffer data grows to a first threshold, the virtual device manager increases the frequency of the function module by a first frequency multiplication coefficient until the input buffer data no longer grows;

[0171] When the function module input buffer data grows to a second threshold, the virtual device manager increases the frequency of the function module by a second frequency multiplication coefficient until the input buffer data no longer grows;

[0172] When the function module input buffer data grows to a third threshold, the virtual device manager uses the highest running frequency of the function module until the input buffer data produces overflow;

[0173] When the function module input buffer data decreases, the virtual device manager uses the function module frequency division coefficient to reduce the frequency until the input buffer data no longer decreases or reaches the minimum threshold or has reached the minimum running frequency of the module.

[0174] As shown in Figure 8 , Figure 8 is a flowchart of scheduling based on a bus arbiter provided in an embodiment of the present application; the bus arbiter in the virtual device manager can be scheduled by the following way:

[0175] The function module processes the current input data, and sends an output request to the bus arbiter, the output request containing a virtual device identifier, an output packet length and other information;

[0176] The bus arbiter looks up the pipeline configuration table according to the virtual device identifier and the identifier of the currently requested function module to obtain the identifier of the next function module;

[0177] If multiple devices simultaneously apply to the bus arbiter for outputting to the input buffer memory of the same function module, the bus arbiter selects one device according to the priority of the device;

[0178] The bus arbiter switches the corresponding switch of the data exchange matrix to send the output data of the device to the input buffer of the next function module in the form of byte stream or bit stream;

[0179] The bus arbiter re-executes the step of looking up the pipeline configuration table according to the virtual device identifier and the identifier of the currently requested function module to obtain the identifier of the next function module.

[0180] In the above manner, the mixed virtual device is implemented by combining function modules using a data pipeline, and the virtual device is scheduled by the data exchange matrix and the bus arbiter, which not only greatly improves the running efficiency of each function module, but also increases the flexibility of device channel expansion and function expansion, reduces the chip redundancy area and chip cost, and balances the power consumption and throughput.

[0195] The audio output unit 1003 can convert audio data received by the radio frequency unit 1001 or the network module 1002 or stored in the memory 1009 into audio signals and output them as sound. Furthermore, the audio output unit 1003 can also provide audio output related to specific functions performed by the electronic device 1000 (e.g., call signal reception sound, message reception sound, etc.). The audio output unit 1003 includes a speaker, a buzzer, and a receiver, etc.

[0196] Input unit 1004 is used to receive audio or video signals. Input unit 1004 may include a graphics processing unit (GPU) 10041 and a microphone 10042. GPU 10041 processes image data of still images or videos acquired by an image capture device (such as a camera) in video capture mode or image capture mode.

Microphone 10042 can receive sound and process such sound into audio data. The processed audio data can be converted into a format that can be transmitted to a mobile communication base station via radio frequency unit 1001 in telephone call mode.

[0197] The electronic device 1000 also includes at least one sensor 1005, such as a light sensor, a motion sensor, and other sensors.

The ambient light sensor can adjust the brightness of the display panel 10061 according to the ambient light level, and the proximity sensor can turn off the display panel 10061 and / or backlight when the electronic device 1000 is moved to the ear. As a type of motion sensor, an accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes).

Specifically, user input unit 1007 includes touch panel 10071 and other input devices 10072. Touch panel 10071, also known as a touch screen, can collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 10071). Touch panel 10071 may include two parts: a touch detection device and a touch controller. The touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, and sends it to processor 1010, which receives and executes commands from processor 1010.

[0200] Furthermore, the touch panel 10071 can cover the display panel 10061. When the touch panel 10071 detects a touch operation on or near it, it transmits the information to the processor 1010 to determine the type of touch event. Subsequently, the processor 1010 provides corresponding visual output on the display panel 10061 based on the type of touch event. Although in Figure 10 In this embodiment, the touch panel 10071 and the display panel 10061 are two independent components to realize the input and output functions of the electronic device. However, in some embodiments, the touch panel 10071 and the display panel 10061 can be integrated to realize the input and output functions of the electronic device.

The processor 1010 may include one or more processing units; preferably, the processor 1010 may integrate an application processor and a modem processor. The application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the processor 1010.

[0204] The electronic device 1000 may also include a power supply 1011 (such as a battery) for supplying power to various components. Preferably, the power supply 1011 can be logically connected to the processor 1010 through a power management system, thereby enabling functions such as managing charging, discharging, and power consumption through the power management system.

[0205] In addition, the electronic device 1000 includes some functional modules not shown, which will not be described in detail here.
