[0035] It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the application. Rather, these embodiments are provided to make the disclosure more thorough and complete, and to fully convey the scope of the disclosure to those skilled in the art.

[0036] Those skilled in the art will understand that the embodiments of this application can be implemented as a system, apparatus, device, method, or computer program product. Therefore, this application can be specifically implemented in the following forms: entirely hardware, entirely software (including firmware, resident software, microcode, etc.), or a combination of hardware and software.

At the same time, the power management unit 110 detects the power output at each port of the power output unit 120 and connects the power output at the port of the power output unit 120 sequentially according to a preset logic, thereby ensuring the timing of power supply to the MPSoC processor and providing stable and reliable power to the MPSoC platform. Meanwhile, the second power output module 20 outputs power to ensure the stable operation of the data transmission module, which facilitates reliable data transmission between the MPSoC processor and the output transmission module. This solves the technical problem that the circuit structure of the power supply circuit in the prior art is complex and cannot meet the complex and diverse power supply requirements of the MPSoC platform, and can more conveniently provide the power to meet the operation of the MPSoC platform.

[0038] It should be noted that the number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0039] The principles and spirit of this application will be explained in detail below with reference to several representative embodiments.

[0040] Reference Figure 1 and Figure 2 , Figure 1 A functional module diagram of a power supply system based on an MPSoC platform provided in an embodiment of this application; Figure 2 This is a schematic diagram of a power tree for a power supply system based on an MPSoC platform, provided as an embodiment of this application.

[0041] An embodiment of this application provides a power supply system based on the MPSoC platform. The power supply system provided in this application may include a first power output module 10 and a second power output module 20.

[0042] The first power output module 10 is configured to receive external power and supply power to the MPSoC processor.

[0043] The first power output module 10 may include a PMIC chip, which can output multiple voltage rails according to its internal power management unit 110, and control the power supply timing of different voltages at its own port. External power can be supplied by a battery or set to grid power. In this embodiment, the input port of the first power output module 10 is electrically connected to a DC 12V power supply.

[0044] The MPSoC processor can be implemented as XZU4EV, XZU4EG, XZU3EG, XCZU2EG, or XCZU1EG.

[0045] For example, in this embodiment, the first power output module 10 can be implemented as two AMP8DSQF65 chips, with different pins set as output ports for outputting different voltages. By connecting the corresponding pins to the corresponding power demand ports of the MPSoC processor, the input port of the first power output module 10 is electrically connected to external power, thereby achieving the purpose of powering the MPSoC processor.

[0046] The second power output module 20 is configured to receive external power and supply power to the data transmission module; wherein, the data transmission module is communicatively connected to the MPSoC processor, and the data transmission module includes an HDMI module, a USB module and / or a DDR module.

[0047] Since the MPSoC processor needs to exchange data with the corresponding data transmission module when it is working, in order to reduce the possibility of the corresponding data transmission module losing power due to external power supply, the second power output module 20 is used to supply power to the data transmission module in this embodiment. This allows the data transmission module to transmit data with the MPSoC processor under a stable power supply, thus facilitating the reliable operation of the MPSoC platform.

[0048] The first power module includes a power management unit 110 and a power output unit 120. The power output unit 120 is provided with multiple output ports for outputting different voltages. The power management unit 110 and the power output unit 120 are communicatively connected. The power management unit 110 is configured to acquire the voltage output by the output port and control the timing sequence of the power output by the power output unit 120.

[0049] This embodiment of the application sets up a first power output module 10 connected to the MPSoC processor. The first power output module 10 can output power corresponding to various voltages and has a high degree of integration. At the same time, the power management unit 110 detects the power output at each port of the power output unit 120 and connects the power output at the port of the power output unit 120 sequentially according to a preset logic, thereby ensuring the timing of power supply to the MPSoC processor and enabling the provision of stable and reliable power to the MPSoC platform. Meanwhile, the second power output module 20 outputs power for the stable operation of the data transmission module, which facilitates reliable data transmission between the MPSoC processor and the output transmission module. This solves the technical problem that the power supply circuit in the prior art is complex and cannot meet the complex and diverse power supply requirements of the MPSoC platform, and can more conveniently provide the power required for the operation of the MPSoC platform.

[0050] In some embodiments, the power output unit 120 includes a first output port 1201 and a second output port 1202.

[0051] The first output port 1201 is electrically connected to the VCCINT port, VCCBRAM port, VCCINT_IO port, VCCPSINTFP port, VCCPS_INTLP port and VCC_PSINTFP_DDR port of the MPSoC processor, and the first output port 1201 is configured to output power with a voltage of 0.85V.

[0052] The first output port 1201 outputs power to the VCCINT port and VPSMGTRAVCC port of the MPSoC processor, generating electrical energy corresponding to the voltage required for the normal operation of the MPSoC processor core.

[0053] The second output port 1202 is electrically connected to the VCCINT_VCU port and VMGTAVCC port of the MPSoC processor, and the second output port 1202 is configured to output power with a voltage of 0.9V.

[0054] The second output port 1202 is used to provide 0.9V of power to the VCU of the MPSOC processor, so as to further power the MPSoC processor according to a preset timing sequence.

[0055] For example, after the power management unit 110 detects that the first output port 1201 outputs 0.85V of power, it generates an enable signal for the second output port 1202 to output power. The power output unit 120 receives the enable signal and causes the second output port 1202 to output power at the corresponding voltage.

[0056] In some embodiments, the power supply system provided in this application further includes a first intelligent power module 30 and a second intelligent power module 40. The first intelligent power module 30 is electrically connected to the first output port 1201 through a power supply circuit, and the first intelligent power module 30 is configured to output 0.85V of electrical energy to the VCCINT port, VCCBRAM port, VCCINT_IO port, VCCPSINTFP port, VCCPS_INTLP port, and VCC_PSINTFP_DDR port of the MPSoC processor.

[0057] The second intelligent power module 40 is electrically connected to the second output port 1202 through a power supply circuit. The second intelligent power module 40 is configured to output 0.9V of electrical energy to the VCCINT_VCU port and VMGTAVCC port of the MPSoC processor.

[0058] For example, the first intelligent power module 30 and the second intelligent power module 40 can be implemented as NCP302035MNTWG power modules. Since the voltage of the electrical energy required to be output by the first output port 1201 and the second output port 1202 is small and the current is large, the output ports of the power output unit 120 can be easily protected by setting the first intelligent power module 30 and the second intelligent power module 40, so as to improve the reliable operation of the first power output module 10.

[0059] Reference Figure 3 , Figure 3 This is a functional module diagram of a power supply system based on an MPSoC platform, provided for another embodiment of this application.

[0060] In some embodiments, in order to facilitate the power supply system based on the MPSoC platform provided in this application to meet the special voltage requirements of the MPSoC platform, the power output unit 120 provided in this application is also provided with a spare port 1203, which is configured to output power of the corresponding voltage according to the voltage programming instruction input by the user.

[0061] For example, the backup port 1203 is capable of adjusting the output voltage of the corresponding port according to the voltage input by the user. In this embodiment, the backup port 1203 is set to VCC_LDO, the continuous current output at the backup port 1203 is 1.5A, the ripple size is 20mV, and the accuracy is ±3%.

[0062] In some embodiments, if the data transmission module is an HDMI module or a USB module, the second power output module 20 provides 5V power to the data transmission module.

[0063] In some embodiments, if the data transmission module is a DDR module, the second power output module 20 includes a first power output unit 120 and a second power output unit 120.

[0064] The first power output unit 120 is electrically connected to the VDDQ port of the data transmission module and is configured to receive external power and output power at a voltage of 1.2V to the VDDQ port of the data transmission module.

[0065] The first power output unit 120 is electrically connected to the VPP port of the data transmission module and is configured to receive external power and output power at a voltage of 2.5V to the VDDQ port of the data transmission module.

[0066] For example, the second power output unit 120 can be implemented as a TPS54620RGY module. The TPS54620RGY module receives power input from the outside and supplies power to the data transmission module according to the type of the data transmission module, so as to realize data transmission between the data transmission module and the MPSoC processor.

[0067] In some embodiments, to further protect the power supply system provided in this application for the first power output module 10 and the second power output module 20, a circuit protection module 50 is further included, which is electrically connected to the input ports of the first power output module 10 and the second power output module 20.

[0068] The circuit protection module 50 can be implemented as an overvoltage protection circuit for power output, which reduces the probability of damage to the first power output module 10 or the second power output module 20 due to improper operation by the user during use.

[0073] S603, the power output unit 120 receives the first enable signal and connects or disconnects the power output of the corresponding port, and feeds back the power output parameters of the corresponding port to the power management unit 110.

[0074] S604, when the error between the electrical energy generated by the power output unit 120 and the parameter corresponding to the power supply command is less than a preset threshold, the power management unit 110 outputs a second enable signal to power the other ports of the power output unit 120 to output the corresponding electrical energy.
