Computer hardware fault diagnosis system based on FPGA

Abstract

The invention discloses a computer hardware fault diagnosis system based on FPGA, which comprises a data processing circuit; the data processing circuit is connected with a data latch circuit; the data latch circuit is connected with a single-chip microcomputer system; the single-chip microcomputer system is connected with a liquid crystal display The circuit is connected; the data processing circuit is respectively connected with the data decoding circuit, the address decoding circuit, the clock circuit and the state machine control. The FPGA-based computer hardware fault diagnosis system of the present invention builds a signal acquisition and processing circuit by programming on the FPGA, and uses the VHDL hardware description language to design a hardware circuit on the FPGA to realize data storage and analysis according to the power-on self-test principle of the computer itself. , extraction and a series of processing; through 51 single-chip microcomputer to control the liquid crystal to realize the Chinese characters of computer hardware failure. When the hardware on the main board of the computer fails, the faulty part can be quickly diagnosed, and the maintenance efficiency of the computer can be improved.

Description

technical field [0001] The invention relates to a computer hardware device, in particular to an FPGA-based computer hardware fault diagnosis system, which belongs to the technical field of computers. Background technique [0002] It is common to use computer as an important tool in today's society. But people are also troubled by their malfunctions affecting their work, and computers are all board designs. If non-professionals can diagnose the fault with the help of a computer fault diagnosis system, it is also feasible to repair it by yourself. Using the power-on self-test of the computer, the self-test program written in the BIOS chip will automatically start when the computer starts [21. After startup, he first checks the CPU, memory, graphics card, hard disk, optical drive / floppy drive and other hardware parts, analyzes and compares the original configuration of the system, and initializes the basic output / input ports and other external devices, and detects no abnormal...
