Description

Technical Field

[0001] This disclosure relates to the field of electronic technology, and more particularly to an electronic device. Background Technology

[0002] With the rapid development of esports and high-end gaming, users' demands for mouse performance are increasing. Traditional mouse report rates are typically below 1kHz, meaning the mouse reports its position and status to the computer a maximum of 1000 times per second. However, with the increase in game screen refresh rates and players' growing demands for operational precision, a 1kHz report rate is gradually becoming insufficient for high-end users. In recent years, the market demand for high report rate mice, such as 4kHz and 8kHz mice, has been growing. A high report rate means the mouse needs to report its position and status to the computer more frequently, thus providing a smoother and more precise control experience. However, achieving a high report rate mouse is not easy, mainly facing the following two challenges: 1) High hardware performance requirements: A high report rate requires higher data processing capabilities and faster transmission speeds, which places higher demands on the mouse's CPU clock speed; 2) Increased power consumption: A high report rate means the mouse needs to perform data acquisition and transmission more frequently, which leads to increased power consumption and affects battery life.

[0003] In conclusion, the market demand for high-report-rate mice is increasingly urgent, but achieving high-report-rate mice still faces many technical challenges. Therefore, developing a mouse that can solve the aforementioned problems in achieving high report rates while ensuring high performance has significant market value and application prospects.

Rather, these embodiments are provided to make this disclosure thorough and complete, and to fully convey exemplary implementation methods to those skilled in the art. The embodiments of this disclosure can be combined in any way to form other embodiments.

[0028] In the following description, embodiments of this disclosure will be exemplarily described using a mouse SoC as an example.

[0029] In some embodiments, when implementing functions such as sensors, scroll wheels, and buttons, the mouse SoC typically uses software to simulate timing via GPIO. Some specific example implementations are shown below.

[0030] 1. Sensor data acquisition based on software simulation timing method:

[0031] The mouse sensor is responsible for sensing or acquiring mouse movement data, such as the mouse's position, coordinates, and displacement. The sensor typically interacts with the SoC (System-on-a-Chip) via the Serial Peripheral Interface (SPI) communication protocol. However, mouse SoCs usually do not integrate a dedicated sensor scanning module; instead, they use GPIO to simulate SPI timing to read sensor data.

[0032] For example, in some embodiments, the SoC simulates SPI timing through GPIO pins; the software simulates the timing of the SPI communication protocol by controlling the high and low levels of the GPIO pins, thereby interacting with the sensor; the sensor transmits the collected motion data to the SoC through GPIO, and the SoC then processes this data.

[0033] This approach may have the following drawbacks:

[0034] Simulating timings using GPIO consumes a significant amount of CPU resources, leading to reduced system efficiency.

[0035] Due to the rate limitation of GPIO, the real-time performance and accuracy of sensor data reading are limited, making it difficult to meet the requirements of high reporting rates (such as 4KHz / 8KHz);

[0036] The timing of software simulations may be unstable, leading to data transmission errors or frame drops.

[0037] 2. Roller signal acquisition based on software simulation timing method:

[0038] Mouse scroll wheels (or scroll wheel devices) typically use encoders or similar devices to detect scrolling actions or corresponding scroll wheel signals. These signals are usually input to the SoC (System-on-a-Chip) via GPIO pins, where software decodes them to determine information such as the scrolling direction and number of steps.

[0039] For example, in some embodiments, the roller encoder outputs two pulse signals (phase A and phase B) with a 90° phase difference, which are connected to two GPIO pins of the SoC, respectively. The software determines the rolling direction (clockwise or counterclockwise, etc.) of the roller by detecting the sequence of level changes on the two GPIO pins. Furthermore, the software can also determine the number of rolling steps by counting the number of pulse signals.

[0040] This approach may have the following drawbacks:

[0041] GPIO level detection and software decoding introduce a certain delay, which affects the real-time performance of the scroll wheel operation;

[0042] In high reporting rate scenarios, the sampling frequency of the scroll wheel signal may be insufficient, leading to the loss or misjudgment of scrolling actions;

[0043] The software decoding implementation consumes a lot of CPU resources, which may affect the overall performance of the mouse.

[0044] 3. Key signal acquisition based on software simulation timing method:

[0045] Mouse buttons (or button devices) typically use mechanical or optical switches, and the state of the button (pressed or released, etc.) can be input to the SoC via GPIO pins.

[0046] For example, in some embodiments, one end of the push-button switch can be connected to a GPIO pin, and the other end grounded. When the button is pressed, the level of the GPIO pin is pulled low; when the button is released, the level of the GPIO pin returns to high. The software detects the button press and release actions or states by periodically scanning the level state of the GPIO pin.

[0047] This approach may have the following drawbacks:

[0048] The software scanning method for GPIO levels introduces a certain delay, affecting the real-time response of buttons;

[0049] In high-reporting-rate scenarios, the sampling frequency of button states may be insufficient, leading to the loss or misjudgment of button actions;

[0050] The software scanning method consumes a lot of CPU resources, which may affect the overall performance of the mouse.

[0051] In other words, the mouse SoC uses GPIO to simulate timing to implement sensor scanning, scroll wheel scanning, and button scanning. While this can meet the needs of mice with low report rates (below 1kHz), it may have the following problems in high report rate (4kHz / 8kHz) scenarios:

[0052] Insufficient real-time performance: The GPIO simulation timing method introduces latency, and the button, scroll wheel and sensor scanning are serial operations, which makes it difficult to meet the real-time requirements of high reporting rates.

[0053] High resource consumption: Software timing simulation consumes a lot of CPU resources, affecting the overall system performance.

[0054] High power consumption: The CPU cannot sleep when GPIO simulates timings. Frequent CPU participation will increase power consumption and affect the mouse's battery life.

[0055] Insufficient accuracy and stability: At high report rates, the sampling frequency and timing stability of GPIO may not be guaranteed, leading to misjudgment of data or uneven sampling, which affects the user experience.

[0056] Therefore, the data acquisition method based on software simulation timing has obvious limitations in the application of high report rate mice, and there is an urgent need for a more efficient and stable implementation solution to meet market demands.

[0057] To address the aforementioned issues, this disclosure proposes a hardware scanning-based mouse SoC design method and architecture. Electronic devices based on this SoC architecture may include one or more of the following modules:

[0058] Hardware-implemented sensor scanning module: The sensor scanning module, implemented through dedicated hardware, communicates directly with the sensor to achieve real-time high-frequency acquisition and processing of sensor data without the need for software or CPU intervention.

[0059] The hardware-implemented roller scanning module detects the pulse signal of the roller encoder in real time through a dedicated hardware decoder, determines the rolling direction and number of steps of the roller, and achieves efficient and accurate roller signal detection.

[0060] Hardware-implemented key scanning module: Real-time detection of key status through dedicated hardware circuitry to reduce key response delay.

[0061] The hardware-implemented data packet module packages the data collected from sensors, scroll wheel, and buttons, generating data packets that conform to the protocol or format for communication on the high-speed bus and with the CPU and / or memory (e.g., Human Interface Device (HID) protocol), and then directly transmits them to the host (e.g., CPU and / or memory).

[0062] The SoC design method or architecture according to embodiments of this disclosure can achieve at least one or more of the following advantages:

[0063] 1) Reduce CPU involvement: By implementing scanning and data packetization of sensors, scroll wheel and buttons through hardware modules, the CPU involvement is significantly reduced, thus reducing system resource consumption.

[0064] 2) Reduced clock speed and power consumption: Due to the high efficiency of the hardware module, the sampling or scanning frequency of the hardware module can be much higher than the working frequency of the CPU or software. Therefore, the SoC can run at a lower CPU clock speed, thereby reducing power consumption and extending the mouse's battery life.

[0065] 3) Achieve high report rate: The real-time performance and high efficiency of the hardware module enable the SoC to achieve a high report rate (such as 4KHz / 8KHz) at a very low clock speed, meeting the performance needs of high-end users.

[0066] 4) Improve user experience: The asynchronous design of the hardware module and uniform data sampling can effectively improve the linearity of the cursor and scroll wheel, reduce data loss and misjudgment, and significantly improve the user's operating experience.

[0067] The design method or architecture disclosed herein overcomes the limitations of traditional software-simulated timing methods in high report rate scenarios through hardware design, providing an efficient, stable, and low-power solution for the implementation of high report rate mice.

[0068] The following description, in conjunction with the accompanying drawings, will further illustrate examples of mouse SoC architectures according to embodiments of this disclosure.

[0084] The error detection and recovery module 206 can be used to resynchronize after a two-wire SPI detects a synchronization failure.

[0085] The low-power management module 207 can be used to manage the power consumption of the module, support sleep and wake-up functions, and optimize energy consumption.

[0086] The working mode configuration module 208 can be used to configure or switch working modes such as configuration mode and scan mode.

[0087] The data transmission module 209 can be used to transmit the acquired and / or processed sensor data to the main control CPU, the data packet module 101, or other peripherals.

[0088] The parameters or settings that need to be configured for the sensor scanning module 102 (and / or the roller scanning module 103, button scanning module 104, data packet module 101, etc. described below) can be obtained from software (e.g., CPU and / or memory, etc.) via the first bus 105, or they can be determined and pre-configured based on the specifications, user manuals, specific timing requirements, etc. of the corresponding peripheral devices such as sensors, and are not limited herein.

[0089] In some embodiments, for example, the scroll wheel scanning module 103 may be connected to the scroll wheel of a mouse.

The two memories, FLASH 610 and RAM 607, can be connected to the CPU 108 via an Advanced High-performance Bus (AHB) 606. The AHB bus 606 may also connect to a USB module (e.g., a USB device controller 611) and an RF module 612 for data transmission in a wired or wireless mouse. The RF module 612 may be an RF module supporting Bluetooth (e.g., Bluetooth Low Energy (BLE)) transmission or any other wireless transmission.

After one or more scanning modules scan data from their respective peripheral devices, they can send a request to the data packet assembly module 101, and the data packet assembly module 101 can directly transfer the relevant data to the RAM 607.

[0123] The three scanning modules and other low-speed peripherals in electronic device 600 can be connected to the Advanced Peripheral Bus (APB) 605, which can be further connected to the AHB bus 606. In addition to the aforementioned digital circuit modules, electronic device 600 may also include analog circuit modules such as a clock module, a power supply module, and a wake-up module.

[0124] As described above, the sensor scanning module 102 in the electronic device 600 may include one or more of the following: a communication interface configuration module 201, a parameter configuration module 202, a sensor configuration module 203, a timing configuration module 204, an interrupt configuration module 205, an error detection and recovery module 206, a low power management module 207, a working mode configuration module 208, and a data transmission module 209.

[0125] A specific implementation of the sensor scanning module 102 is shown below.

[0126] The communication interface configuration module 201 is configured for 2-wire / 4-wire SPI selection and multiplexed pin configuration of GPIOs (e.g., GPIO 109 or other GPIOs connected to the corresponding scan module and / or peripheral devices).

[0127] The parameter configuration module 202 is used to configure parameters such as scanning frequency, scanning mode, sensor coordinate data format, and sensor coordinate high-order data format (only applicable to 12-bit and 16-bit coordinate data formats). The high-order data format refers to the arrangement of the high-order and low-order bytes when storing multi-byte data in memory. For example, in some embodiments, the high-order data format may include big-endian, little-endian, etc.

[0128] The sensor configuration module 203 is used to configure some register addresses and / or related data of the sensor to be scanned. These addresses and / or data may include one or more of the following: sensor ID register address, sensor ID value, sensor motion status register address, sensor X-axis coordinate low-order data register address, sensor Y-axis coordinate low-order data register address, sensor coordinate high-order data register address 1, and sensor coordinate high-order data register address 2.

[0129] The timing configuration module 204 configures the TR and TNS registers to meet the specific timing requirements of different sensors for SPI. The TR register is used to configure the timing parameters of DATA in SPI communication. The TNS register is used to configure the timing parameters of NCS in SPI communication.

[0130] The error detection and recovery module 206 adjusts the high and low levels of the serial clock (SCLK) signal by configuring the resynchronization (RESYNC) register, thereby achieving the purpose of resynchronizing the two-wire SPI when the configured and / or acquired sensor IDs are inconsistent.

[0131] The interrupt configuration module 205 can be used to enable or disable one or more interrupt modes, such as scan completion interrupt, resynchronization start interrupt, resynchronization end interrupt, interrupt triggered during resynchronization when scanning occurs, and configuration mode completion interrupt. One or more of these interrupt modes can be enabled according to actual needs. For example, if the scan completion interrupt is enabled, an interrupt will be triggered when the scan is completed.

[0132] The low-power management module 207 may include circuitry that enables or disables low-power modes (e.g., sleep mode) and wake-up modes. For example, it may be used to enable the wake-up function when needed, while the system is in a low-power mode to save power.

[0133] The operation process of the sensor scanning module 102 may include a sensor initialization process and a scanning process.

[0134] During the sensor initialization process, the operating mode of the sensor scanning module 102 can be set to configuration mode via the operating mode configuration module 208. Next, sensor data read / write operations can be performed by manipulating the CFG_ADDR and CFG_DATA registers in the sensor scanning module 102, enabling a series of sensor-customized initialization processes such as sensor reset, calibration, and parameter configuration.

[0135] Before the scan begins, a scan completion interrupt can be enabled via the interrupt configuration module 205. For example, after the scan completion interrupt is enabled, the corresponding status bit in the interrupt status register can be set (e.g., set to 1 or 0) when the scan is complete.

[0136] In the scanning process, the working mode of the sensor scanning module 102 can be switched to scan mode by the working mode configuration module 208 to start data acquisition or scanning. For example, the scanning function of the sensor scanning module 102 can be enabled to start data acquisition or scanning.

[0137] Finally, the collected or acquired X-axis and Y-axis coordinate data can be transmitted through the data transmission module 209 and processed accordingly.

[0138] In some embodiments, the above-mentioned modules or functions of the sensor scanning module 102 can be implemented by one or more registers and related circuits as shown in Table 1 below.

[0139] [Table 1]

[0140]

[0141]

[0142] The roller scanning module 103 may include one or more of the following: parameter configuration module 301, interrupt configuration module 302, signal input module 303, low power management module 304, status indication module 305, and data transmission module 306.

[0143] The operation process of the roller scanning module 103 may include an initialization configuration process and a scanning process.

[0144] During the initialization configuration process, the signal input module 303 can be used to configure the multiplexed pins of GPIO (e.g., GPIO 109 or other GPIOs connected to the corresponding scan module and / or peripheral devices) for connecting the output signals of the roller. That is, the signal input module 303 is used to configure the GPIO multiplexing function.

[0145] The parameter configuration module 301 can be composed of one or more sub-configuration circuits. For example, the operating mode, scanning frequency, and de-jitter time of the roller scanning module 103 can be configured separately through these one or more sub-configuration circuits.

[0146] One or more interrupts (e.g., scroll wheel event triggered interrupt) can be enabled or disabled through the interrupt configuration module 302.

[0147] The low-power management module 304 may include circuitry that enables or disables low-power modes (e.g., sleep mode) and wake-up modes. For example, it may be used to wake up the system when needed by enabling the wake-up function when the system is in a low-power mode to save power.

[0148] After completing one or more of the above configurations, the roller scanning module 103 can be enabled to start the scanning process.

[0149] For example, if the above-mentioned scroll event trigger interrupt is configured to be enabled, an interrupt will be triggered when a scroll event or scroll data is scanned.

[0150] After successfully scanning for data, the corresponding status bit of the status indicator module 305 can be set, for example, to 1 or 0. This status bit can be used to indicate whether data was successfully scanned, or whether the current data is valid, etc.

[0151] Finally, the collected or acquired roller data can be transmitted through the data transmission module 306 and processed accordingly.

[0152] In some embodiments, the above-described modules or functions of the roller scanning module 103 can be implemented by one or more registers and related circuits as shown in Table 2 below.

[0153] [Table 2]

[0154]

[0155] The key scanning module 104 may include one or more of the following: parameter configuration module 401, interrupt configuration module 402, signal input module 403, low power management module 404, status indication module 405, and data transmission module 406.

[0156] The operation process of the key scanning module 104 may include an initialization configuration process and a scanning process.

[0157] During the initialization configuration process, the signal input module 403 can be used to configure the multiplexed pins of GPIO (e.g., GPIO 109 or other GPIOs connected to the corresponding scan module and / or peripheral devices) for detecting the level state of the button. That is, the signal input module 403 is used to configure the GPIO multiplexing function.

[0158] The parameter configuration module 401 can be composed of one or more sub-configuration circuits. For example, the key mode (such as three-key or five-key selection), scanning mode, scanning frequency, and debouncing time can be configured separately through these one or more sub-configuration circuits.

[0159] One or more interrupts (e.g., key press trigger interrupt) can be enabled or disabled through the interrupt configuration module 402.

[0160] The low-power management module 404 may include circuitry that enables or disables low-power modes (e.g., sleep mode) and wake-up modes. For example, it may be used to wake up the system when needed by enabling the wake-up function when the system is in a low-power mode to save power.

[0161] After completing one or more of the above configurations, the key scanning module 104 can be enabled to start the scanning process.

[0162] For example, if the above-mentioned key press trigger interrupt is configured to be enabled, an interrupt will be triggered when a key press is detected. At the same time, the corresponding status bit of the status indicator module 405 can be set, for example, to 1 or 0.

[0163] Finally, the collected or acquired key scan results (each bit of the data register corresponds to the pressing state of a key) can be transmitted through the data transmission module 406 and processed accordingly.

[0164] In some embodiments, the above-mentioned modules or functions of the key scanning module 104 can be implemented by one or more registers and related circuits as shown in Table 3 below.

[0165] [Table 3]

[0166]

[0167] The data package module 101 may include one or more of the following: data transport module 501, configuration module 502, and status indication module 503.

[0168] The configuration module 502 can be composed of one or more sub-configuration circuit sections. For example, the data source address (e.g., source register address) and target RAM address (e.g., target address in RAM) of the button scanning module 104, sensor scanning module 102, and scroll wheel scanning module 103 can be configured separately through these one or more sub-configuration circuits. Typically, the data length of the buttons and scroll wheel is only one byte, but the bit width of the coordinate data of different sensors may be different, so the bit width of the coordinate data can also be configured through the configuration module 502.

[0169] After one or more of the key scanning module 104, sensor scanning module 102 and / or roller scanning module 103 scans data, the scanning module that scanned the data can send a data transfer request to the data packet module 101. At the same time, if the data transfer function of the data packet module 101 is enabled, the data transfer module 501 can transfer the scanned data from the source register to the RAM according to the configuration in the configuration module 502.

[0170] After the data transfer is completed, the corresponding status bit in the status indicator register in the status indicator module 503 can be set, for example, to 1 or 0.

[0171] In some embodiments, the above-mentioned modules or functions of the data packet module 101 can be implemented by one or more registers and related circuits as shown in Table 4 below.

[0172] [Table 4]

[0173]

[0174] When applying the above SoC to mouse products (taking the data width of 1 byte as an example), a four-byte array mouse_data[4] can be defined in the firmware program to store button data, X coordinate data, Y coordinate data and scroll wheel data in sequence.

[0175] First, each scanning module can be initialized and configured. Then, the data packet assembly module can be initialized by enabling the data transfer function of each scanning module through the CONFIG register, setting the coordinate data bit width to 1 byte, setting the data source address to the corresponding source data register address of the scanning module, and setting the data destination address to the corresponding address in the mouse_data array. Finally, the functions of each scanning module are enabled again, and scanning begins.

[0176] If the mouse is not in use, the SoC can remain in sleep mode. When one or more of the following actions occur—button press, movement, or scroll wheel movement—the corresponding hardware scanning module will collect data according to its initialization configuration and transmit the data to the target address mouse_data array configured in the firmware according to the source address configuration of the data packet assembly module. Simultaneously, since the wake-up function is enabled in the initialization configuration of each scanning module, the CPU will also be woken up. The woken-up CPU will then query the status bits of the DATD_VALID_STATUS register of the data packet assembly module. If one or more status bits are set, it means that the data packet assembly module has moved the scanned corresponding data to the mouse_data array. The CPU then sends the mouse_data to the host via the USB or RF interface and then returns to sleep mode.

[0177] The embodiments disclosed herein innovatively propose a mouse SoC design method and architecture including a hardware-based sensor scanning module, a scroll wheel scanning module, a button scanning module, and a data packet assembly module. The mouse SoC implemented through this design method or architecture not only has significant advantages in high performance, low power consumption, and user experience, but also provides a completely new technical route for mouse SoC design, possessing significant innovative value and application potential within the industry.
