Computer fault-tolerant device based on domestic Loongson processor connection

Abstract

The invention relates to the technical field of main control units of ground core information control devices, in particular to a computer fault-tolerant device based on domestic Loongson processor connection. According to the computer fault-tolerant device in the technical scheme, fault detection of dual-computer-data-state-shared synchronous consistency and handshake mutual inspection is achieved through a specific interstage-connection interface of a domestic Loongson 3A multi-core processor and the specific high-speed bi-direction technology, the specific serial point-to-point technology, the specific packet switching technology, the specific virtual channel technology, the specific out-of-order execution technology and the like of a HT bus. According to the computer fault-tolerant device, the defects of the reliability and resource development of a domestic general processor are effectively overcome; according to redundant backup and fault tolerance design of s system function, the safety, the reliability and the testing performance of a core main control unit in an information system are fully improved, and the workability and the applicability after the information system is subjected to domestication construction are powerfully guaranteed.

Description

technical field [0001] The invention relates to the technical field of the main control unit of ground core information control equipment, in particular to a computer fault tolerance device based on the interconnection between domestic Loongson processors. Background technique [0002] In the daily application of the main control unit of information control equipment, a large amount of data supervision and information application work has been completed, which is directly related to the working performance of the entire information system. Plagued by factors such as information security, domestically produced processors have become the preferred choice for information systems. However, due to insufficient testing and weak technology, computer systems based on domestically produced processors often have low reliability, lack of backup measures, and are difficult to meet actual use requirements. [0003] Existing localized computer systems often have the following deficiencie...

AI Technical Summary

Problems solved by technology

[0004] The functions of each host computer in the system are independent of each other, without forming a system, even if the data is exchanged through the traditional bus, the quantity is insufficient, the value is limited, it is difficult to carry out deeper analysis and application, and the performance characteristics of the computer system cannot be fully utilized;

[0005] The functional modules of each host in the system overlap with each other, and the required functions cannot be completed independently. The flexibility of the system configuration is insufficient, and there is a single point of failure mode in the system, which seriously affects the reliability of the system;

[0006] There is a lack of necessary detection and diagnosis mechanisms among the hosts in the system. Faults or errors, especially program runaway phenomena, are difficult to effectively isolate, and the adaptability of the entire system to faults cannot be guaranteed.
