Design method for twinbridge piece mainboard redundancy

Abstract

The invention relates to a design method for twinbridge piece mainboard redundancy. A twinbridge piece mainboard adopted in the method comprises a CPU (central processing unit)-south and north bridge system 1, a CPU-south and north bridge system 2 and a monitoring circuit, wherein the CPU-south and north bridge system 1 and the CPU-south and north bridge system 2 are symmetrically arranged at two sides of the monitoring circuit. The method comprises the following steps that an initial state is determined, the CPU-south and north bridge system 1 is electrified, in addition, pulse signals and signal codes are sent to the monitoring circuit; whether the signals of a serial port and a lead wire of the CPU-south and north bridge system 1 are normal or not is judged; the signal codes are sent to the monitoring circuit; whether the signals of a lead wire interface, a serial port and an Internet access are normal or not is judged; and the states of the CPU-south and north bridge system 1 and the CPU-south and north bridge system 2 are transmitted to remote control terminal equipment. The design method for twinbridge piece mainboard redundancy provided by the invention has the advantages that the reliable and stable operation of a loongson CUP is ensured in the aspect of redundancy design, and the normal operation of the reliable data and business under the accident suffering condition is ensured.

Description

technical field

[0001] The invention relates to a design method, in particular to a redundant design method for a double-bridge main board. Background technique

[0002] Loongson 3 series CPUs include 4-core 3A, 8-core 3B, 8-core or 16-core 3C CPUs, as well as other series of CPUs that will be developed later. Godson 3A CPU has been mass-produced, and the other two CPUs are still in the research and development stage.

[0003] Loongson-3 CPU is a general-purpose multi-core CPU. It adopts MIPS architecture and can fully realize the functions of Intel and AMD X86 architecture CPUs. Although it is slightly behind X86 CPU in terms of performance, it can completely replace X86 CPU in most fields. .

[0004] Although the Loongson 3A and 3B CPUs have been released, the key problem of "use" has not been solved, that is, the north and south bridge chipsets and peripherals that match the Loongson CPU and can work normally have not been found. In order to solve the practical problem...
