[0021] The cloud computer thin terminal provided in the embodiments of the present application comprises a central processor, a power management module and a peripheral control module, the central processor is connected with the power management module and the peripheral control module through a bus respectively; wherein the clock domain of the central processor is extended to a preset value; the power management module communicates with the central processor through the bus and adjusts the power according to the power control instruction issued by the central processor; the peripheral control module communicates with the central processor through the bus and adjusts the target peripheral device according to the peripheral control instruction issued by the central processor. In the embodiments of the present application, the clock domain of the central processor in the cloud computer thin terminal is extended to a preset value, so that the central processor has the power management function and the peripheral control function, and the power management module and the peripheral control module are connected with the central processor through the bus and directly communicate, without the forwarding of the EC, the inherent signal transmission delay is reduced, the problem of inaccurate control due to the delay is reduced, the data conversion loss of the intermediate layer is eliminated, and thus the accuracy of the control of the central processor is improved.
[0022] Embodiment 1 Figure 1 A structure diagram of the cloud computer thin terminal provided in the embodiments of the present application is provided, the cloud computer thin terminal comprises a central processor 101, a power management module 102 and a peripheral control module 103, the central processor 101 is connected with the power management module 102 and the peripheral control module 103 through a bus respectively; wherein the clock domain of the central processor 101 is extended to a preset value; The power management module 102 is used for communicating with the central processor 101 through the bus and adjusting the power according to the power control instruction issued by the central processor 101; The peripheral control module 103 is used for communicating with the central processor 101 through the bus and adjusting the target peripheral device according to the peripheral control instruction issued by the central processor 101.
[0023] The cloud computer thin terminal provided in the embodiments of the present application is generally a domestic cloud computer thin terminal, that is, the elements in the cloud computer thin terminal generally adopt domestic elements, so as to avoid the risk of technical blockade and supply chain interruption caused by the dependence on imported suppliers.
[0024] Specifically, the cloud computer thin terminal in the embodiments of the present application comprises a central processor 101, a power management module 102 and a peripheral control module 103. For example, the central processor 101 can adopt a domestic HiSilicon M900 master control chip, etc.; the power management module 102 can adopt a domestic power management unit (PMU) chip, etc., which is not limited specifically herein.
[0025] The central processor 101 is connected with the power management module 102 through a bus, and the central processor 101 is connected with the peripheral control module 103 through a bus.
[0026] Therefore, the power management module 102 can directly communicate with the central processor 101 through the bus without forwarding through the EC, thereby reducing the data transmission delay; and the peripheral control module 103 can also directly communicate with the central processor 101 through the bus without forwarding through the EC, thereby reducing the data transmission delay.
[0027] In order to enable the central processor 101 to support the functions (such as power management function and peripheral control function) possessed by the traditional EC, in the embodiment of the present application, the clock domain of the central processor 101 is also extended to a preset value. For example, taking a domestic HiSilicon M900 master control chip as the central processor 101, the clock domain of the domestic HiSilicon M900 master control chip is extended to a preset value, so that the hardware management core of the domestic HiSilicon M900 master control chip can take over the functions of the traditional EC.
[0028] The preset value is calculated according to the required frequency of the peripheral device and the power supply, so that the central processor 101 whose clock domain is extended to the preset value can have the power management function and the peripheral control function; in a possible implementation, the preset value calculated according to the required frequency of the peripheral device and the power supply is 32 megahertz (MHz).
[0029] The peripheral control function includes but is not limited to keyboard scanning, mouse scanning, fan speed regulation, etc., which are not limited here.
[0030] Since the central processor 101 whose clock domain is extended to the preset value has the power management function, after receiving the power-related data sent by the power management module 102, the central processor 101 can analyze the power-related data, determine the power control instruction, and send the power control instruction to the power management module 102 through the bus, so that the power management module 102 can make corresponding adjustments to the power supply according to the power control instruction after receiving the power control instruction, thereby realizing dynamic voltage rail control.
[0031] Since the central processor 101 whose clock domain is extended to the preset value has the peripheral control function, after receiving the peripheral-related data sent by the peripheral control module 103, the central processor 101 can analyze the peripheral-related data, determine the peripheral control instruction, and send the peripheral control instruction to the peripheral control module 103 through the bus, so that the peripheral control module 103 can determine the target peripheral device corresponding to the peripheral control instruction after receiving the peripheral control instruction, and make adjustments to the target peripheral device according to the peripheral control instruction.
[0032] In a possible implementation, the central processor 101 can include a hardware management controller (HMC), and the real-time control logic is executed through the HMC, that is, the power regulation instruction and the peripheral control instruction are determined.
[0033] In the conventional cloud computer thin terminal, a double-layer architecture design is adopted, in which the main control chip and the EC are cooperated, that is, the main control chip and the EC chip are both mounted on a printed circuit board (PCB), but the EC chip usually needs to be matched with a power stabilizer, a level converter and other peripheral circuits, which increases the material cost and occupies more PCB area. Therefore, the EC cloud computer thin terminal provided in the embodiment saves the hardware cost caused by the EC chip and the peripheral circuit, for example, the PCB area is reduced by 18%, and the hardware cost is reduced by 4%.
[0034] In addition, in the conventional cloud computer thin terminal, an EC special firmware (code amount: about 20-50 KB) needs to be developed to realize the power management and keyboard scanning and other basic functions, and the protocol compatibility problem between the EC and the main control chip needs to be solved, which significantly prolongs the development cycle. The EC cloud computer thin terminal designed in the application not only reduces the hardware design difficulty and shortens the hardware development cycle, but also improves the hardware reliability.
[0035] In addition, the conventional cloud computer thin terminal also has the problem of prominent energy consumption short board: the standby power consumption of the EC chip is 0.8 watt (W), and the firmware polling mechanism of the EC will cause the related data line to be continuously active, which will generate additional leakage current. Therefore, the EC cloud computer thin terminal provided in the embodiment reduces the energy consumption caused by the EC and improves the product endurance.
[0036] In the embodiment, the clock domain of the central processor in the cloud computer thin terminal is extended to a preset value, so that the central processor has power management function and peripheral control function, and the power management module and the peripheral control module are connected with the central processor through a bus and directly communicate, without the forwarding of the EC, which reduces the inherent signal transmission delay, reduces the problem of inaccurate control caused by the delay, eliminates the data conversion loss of the intermediate layer, and improves the accuracy of the central processor control.
[0037] Embodiment 2: In order to realize power regulation, on the basis of the above-mentioned embodiments, in the embodiment, the power management module 102 is specifically configured to collect power data and send the power data to the central processor 101 through a bus. The central processor 101 is specifically configured to receive power supply data, obtain a predicted power supply voltage and a predicted power supply frequency according to the power supply data by using a dynamic voltage and frequency scaling algorithm, and send a power supply regulation instruction carrying the predicted power supply voltage and the predicted power supply frequency to the power supply management module 102 through a bus. The power supply management module 102 is specifically configured to receive the power supply regulation instruction, determine the predicted power supply voltage and the predicted power supply frequency carried in the power supply regulation instruction, and adjust the power supply according to the predicted power supply voltage and the predicted power supply frequency.
[0038] In the embodiment of the application, the power supply management module 102 monitors the power supply and collects power supply data, where the power supply data includes but is not limited to power supply voltage, power supply current and the like, and sends the collected power supply data to the central processor 101 through the bus.
[0039] In one possible implementation, the power supply is integrated in the power supply management module 102.
[0040] The central processor 101 receives the power supply data. In one possible implementation, there is a register space in the central processor 101 of the embodiment of the application, and the data (such as power supply data and peripheral device data) transmitted from the bus to the central processor 101 is temporarily stored in the register space, that is, the register space of the central processor 101 is used to receive the data transmitted from the bus, so as to facilitate subsequent reading, analysis and the like of the data stored in the register space.
[0041] After the register space of the central processor 101 receives the power supply data, the central processor 101 obtains the predicted power supply voltage and the predicted power supply frequency based on a load prediction model by using a dynamic voltage and frequency scaling algorithm according to the power supply data and the saved load condition of the current central processor 101, and encapsulates the predicted power supply voltage and the predicted power supply frequency into a power supply regulation instruction, and returns the power supply regulation instruction carrying the predicted power supply voltage and the predicted power supply frequency to the power supply management module 102 through the bus.
[0042] After the power supply management module 102 receives the power supply regulation instruction, the power supply management module 102 analyzes the power supply regulation instruction, determines the predicted power supply voltage and the predicted power supply frequency carried in the power supply regulation instruction, and adjusts the voltage of the power supply to the predicted power supply voltage and adjusts the frequency of the power supply to the predicted power supply frequency.
[0043] In a possible implementation, the central processor 101 is further capable of obtaining a predicted power supply voltage, a predicted power supply frequency and a predicted power supply phase based on a load prediction model according to the power supply data and the saved current load of the central processor 101, and encapsulating the predicted power supply voltage, the predicted power supply frequency and the predicted power supply phase into the power supply regulation instruction, and returning the power supply regulation instruction carrying the predicted power supply voltage, the predicted power supply frequency and the predicted power supply phase to the power supply management module 102 through the bus.
[0044] The power supply management module 102 receives the power supply regulation instruction, analyzes the power supply regulation instruction, determines the predicted power supply voltage, the predicted power supply frequency and the predicted power supply phase carried in the power supply regulation instruction, and adjusts the voltage of the power supply to the predicted power supply voltage, adjusts the frequency of the power supply to the predicted power supply frequency, and adjusts the power supply phase of the power supply to the predicted power supply phase.
[0045] In addition, the power supply management module 102 provided in the embodiments of the present application further has an overcurrent protection circuit built-in, and when it is detected that the power supply current exceeds a certain preset threshold, the corresponding protection measures are started to implement multi-level power supply fault isolation.
[0046] In the embodiments of the present application, the central processor and the power supply management module communicate through the bus, and this process does not need the forwarding of the middleware (such as EC), so that the voltage switching response time is shortened, for example, the voltage switching response time of the traditional EC scheme is 50 μs, while the voltage switching response time of the cloud computer thin terminal structure using the embodiments of the present application is compressed to 5 μs. Moreover, the central processor determines the power supply regulation instruction and delivers it to the power supply management module, which can realize the regulation of the power supply.
[0047] Embodiment 3 In order to realize the regulation of the peripheral device, on the basis of the above-mentioned embodiments, the cloud computer thin terminal further includes a plurality of peripheral devices in the embodiments of the present application. Each peripheral device is configured to collect the peripheral device data corresponding to the peripheral device, and send the peripheral device data and the identification information corresponding to the peripheral device to the peripheral device control module 103. The peripheral device control module 103 is specifically configured to, when receiving the peripheral device data and the corresponding identification information sent by any peripheral device, forward the peripheral device data and the corresponding identification information to the central processor 101 through the bus. The central processor 101 is specifically configured to determine the target peripheral device to be regulated and the corresponding target peripheral device data according to the received peripheral device data and the corresponding identification information, and send a peripheral device regulation instruction carrying the target identification information of the target peripheral device and the target peripheral device data to the peripheral device control module 103. The peripheral device control module 103 is specifically configured to receive and analyze the peripheral device regulation instruction, determine the target peripheral device and corresponding target peripheral device data, and adjust the target peripheral device based on the target peripheral device data.
[0048] In the embodiments of the present application, the cloud computer thin terminal further includes a plurality of peripheral devices, such as a fan, a sensor (such as a temperature sensor, a cover opening and closing sensor, etc.), a keyboard, a mouse, a light emitting diode (LED) indicator light, a screen, etc., which are not specifically limited here.
[0049] Each peripheral device can collect its own corresponding peripheral device data. For example, if the peripheral device is a fan, the peripheral device can collect its own corresponding fan speed and collect the fan speed as its own corresponding peripheral device data.
[0050] After the peripheral device collects its own corresponding peripheral device data, the peripheral device sends the peripheral device data and the identification information corresponding to the peripheral device to the peripheral device control module 103.
[0051] When the peripheral device control module 103 receives the corresponding peripheral device data and identification information sent by any peripheral device, it can forward the peripheral device data and the corresponding identification information to the central processing unit 101 through the bus.
[0052] If the peripheral device control module 103 receives the corresponding peripheral device data and identification information sent by multiple peripheral devices at the same time, the peripheral device control module 103 can aggregate the peripheral device data and identification information corresponding to the multiple peripheral devices, and forward the aggregated data to the central processing unit 101 through the bus.
[0053] After the central processing unit 101 receives the peripheral device data and the corresponding identification information, it determines the related peripheral devices associated with the peripheral device corresponding to the identification information according to the identification information, and determines whether the related peripheral devices need to be regulated according to the peripheral device data, and determines the target peripheral device to be regulated and the corresponding target peripheral device data.
[0054] The target peripheral device and the peripheral device corresponding to the received identification information can be the same or different. For example, the central processing unit 101 receives the first temperature data corresponding to the temperature sensor and the identification information, determines that the related peripheral devices associated with the temperature sensor include the LED indicator light, and determines that the first temperature data corresponding to the temperature sensor exceeds the preset temperature threshold, then determines that the LED indicator light needs to be regulated, and determines the LED indicator light as the target peripheral device to be regulated, and the brightness and color to which the LED indicator light needs to be adjusted as the corresponding target peripheral device data.
[0055] In another example, the central processor 101 receives second temperature data corresponding to a Negative Temperature Coefficient (NTC) sensor array and identification information, determines that a related peripheral device associated with the NTC sensor array includes a fan, and determines that the fan is a target peripheral device to be controlled. The central processor 101 determines fan speed data that needs to be adjusted for the fan based on the second temperature data and saved set temperature data, and based on a fuzzy Proportional-Integral-Derivative (PID) algorithm, and uses the fan speed data as corresponding target peripheral device data, so that a subsequent Pulse Width Modulation (PWM) speed regulator of the fan adjusts the fan speed based on the target peripheral device data.
[0056] After determining the target peripheral device to be controlled and the corresponding target peripheral device data, the central processor 101 encapsulates the target identification information of the target peripheral device and the corresponding target peripheral device data into a peripheral control instruction, and sends the peripheral control instruction carrying the target identification information of the target peripheral device and the corresponding target peripheral device data to the peripheral control module 103 through a bus.
[0057] After receiving the peripheral control instruction, the peripheral control module 103 analyzes the peripheral control instruction, determines the target identification information of the target peripheral device and the corresponding target peripheral device data carried in the peripheral control instruction, and sends the target peripheral device data to the target peripheral device corresponding to the target identification information, so that the target peripheral device adjusts according to the target peripheral device data.
[0058] In the embodiments of the present application, the central processor sends the peripheral control instruction carrying the target identification information of the target peripheral device and the target peripheral device data to the peripheral control module, which can realize the control of the target peripheral device.
[0059] Embodiment 4: On the basis of the above embodiments, in the embodiments of the present application, the peripheral device is connected to the peripheral control module through a Universal Serial Bus Hub (USB HUB) dedicated port and / or a General-Purpose Input / Output (GPIO) interface.
[0060] In the embodiment of the present application, the peripheral control module 103 can adopt a domestic USB HUB chip and a domestic GPIO expander to form a cooperative architecture, that is, the peripheral control module 103 is connected with each peripheral device through a USB HUB special port and / or a GPIO interface.
[0061] If a certain peripheral device is connected with the peripheral control module 103 through the USB HUB special port, the peripheral device sends the peripheral device data and the identification information corresponding to the peripheral device collected by the peripheral device to the peripheral control module 103 through the corresponding USB HUB special port.
[0062] If a certain peripheral device is connected with the peripheral control module 103 through the GPIO interface, the peripheral device sends the peripheral device data and the identification information corresponding to the peripheral device collected by the peripheral device to the peripheral control module 103 through the GPIO interface.
[0063] In a possible implementation, the peripheral device connected with the peripheral control module 103 through the USB HUB special port is a keyboard or a mouse.
[0064] For example, the keyboard is connected with the peripheral control module 103 through the USB HUB keyboard special port, so that the scan delay of the traditional PS / 2 (Personal System / 2) interface can be eliminated.
[0065] For another example, the mouse is connected with the peripheral control module 103 through the USB HUB mouse special port, so that the scan delay of the traditional PS / 2 (Personal System / 2) interface can be eliminated.
[0066] Specifically, if the peripheral device is a keyboard or a mouse, the keyboard or the mouse sends the scan signal (that is, the keyboard scan signal or the mouse scan signal) and the corresponding identification information to the central processing unit 101 through the peripheral control module 103, and the central processing unit 101 can identify the information input by the keyboard or the mouse according to the keyboard scan signal or the mouse scan signal after receiving the keyboard scan signal or the mouse scan signal.
[0067] It can be understood that the peripheral device connected with the peripheral control module 103 through the USB HUB special port is not limited to the keyboard or the mouse, which is not described here.
[0068] In another possible implementation, the peripheral device connected with the peripheral control module 103 through the GPIO interface is a sensor or an indicator.
[0069] It can be understood that the peripheral device connected with the peripheral control module 103 through the GPIO interface is not limited to the sensor or the indicator, which is not described here.
[0070] Embodiment 5 In order to realize the fast wake-up of the central processor, on the basis of the above embodiments, in the embodiment of the present application, an Application Processor Low-Power Domain (APL) domain is integrated in the central processor 101. The power management module 102 is also configured to send the wake-up signal to the central processor 101 through the bus if the wake-up signal is identified. The APL domain in the central processor 101 is configured to capture the wake-up signal and perform a wake-up operation on the central processor 101.
[0071] In the conventional cloud computer thin terminal, during the system power-on stage, the EC is started in priority to the master chip, and loads the firmware through the built-in Read-Only Memory (ROM) to complete the initialization of each interface and Analog to Digital Converter (ADC) module installed on the EC, and then sends a Power Button Signal (PWRBTN#) to wake up the master chip and deliver hardware configuration parameters (such as battery capacity, temperature state, etc.), resulting in a long wake-up response time of the master chip (i.e. the central processor).
[0072] In the embodiment of the present application, the APL domain is integrated in the central processor 101, so that when the power management module 102 identifies the wake-up signal and sends it to the central processor 101 through the bus, the APL domain in the central processor 101 can capture the wake-up signal, realize the fast switching of the SOix low-power state, and thus wake up the central processor 101.
[0073] The wake-up signal includes, but is not limited to, a power button pulse signal, a cover opening and closing detection signal, etc., which are not specifically limited herein.
[0074] In the embodiment of the present application, by integrating the APL domain in the central processor, the APL captures the wake-up signal and performs a wake-up operation on the central processor, which realizes the fast wake-up of the central processor and reduces the wake-up response time.
[0075] In addition, based on the above-mentioned embodiments, the application further constructs a full-stack domestication driving architecture: a no-EC driving engine compatible with ACPI 6.4 is developed at the software level, which includes a PEP-Engine and a HAL. The PEP-Engine can replace the decision logic of the traditional EC firmware and issue orders (such as reducing the temperature), and the HAL layer can convert the orders into specific indicators (such as reducing the screen brightness by 2 notches and adjusting the fan speed to 2800 notches).
[0076] In addition, the application further provides a hardware-software collaborative design scheme, that is, the cloud computer thin terminal is also installed with an operating system, which can directly read the power data stored in the register space. For example, the domestic HiSilicon M900 master control chip is taken as the central processing unit 101, and the GPIO / SMBus register space of the domestic HiSilicon M900 master control chip is remapped, so that the operating system can directly analyze the data temporarily stored in the register space.
[0077] Embodiment 6: Based on the same concept, based on the above-mentioned embodiments, the application provides a data processing method, Figure 2 A data processing process diagram is provided for the application embodiment, and the process includes: S201: communicate with the power management module through the bus, and issue a power regulation instruction to the power management module, so that the power management module adjusts the power according to the power regulation instruction.
