A computer system monitoring circuit

Abstract

The invention discloses a monitoring circuit of a computer system. The monitoring circuit includes an ARM processor, an FPGA, a memory and a voltage and temperature measurement circuit. The ARM processor, the voltage and temperature measurement circuit are connected to the FPGA in a communication manner; the memory is separately connected to the ARM processor and the FPGA; the ARM processor is used for collecting a voltage value of a mainboard battery and operating conditions of the mainboard battery and external devices for the same, and recording device fault information; the FPGA is used for collecting working time of the mainboard, power-on number, temperature information of the mainboard, the voltage value of each chip of the mainboard, and recording the abnormal information of powersupply; and the ARM processor generates a fault indication signal according to the device fault information or the abnormal information of the power supply, and is used for generating corresponding alarm information according to the device fault information or the abnormal information of the power supply, and sending the alarm information to a processor platform through the FPGA. The monitoring circuit can achieve real-time monitoring and recording the operating conditions of the mainboard battery and external devices for the same of the computer system, and provides reference data for debugging and improvement and perfection of newly developed computer systems.

Description

technical field

[0001] The invention belongs to the technical field of computer hardware design, and more specifically relates to a monitoring circuit applied to a computer system of a Godson processor platform. Background technique

[0002] For a long time, my country's computing equipment has adopted a large number of foreign software and hardware products, and core technologies such as high-performance processors and operating systems have been completely closed to us. Technology is controlled by others and there are security risks. Especially in the field of national defense and military industry, in order to avoid being subject to imported processors during wartime, the development and use of domestic processors has become an urgent and necessary requirement. With the rapid development and gradual improvement of domestic processor chips, their performance has begun to match imported processors, and their applications in the field of national defense and industrial produ...
