Method and system for implementing inter-core backup in multi-core processor

Abstract

The invention discloses a method and a system for implementing inter-core backup in a multi-core processor to implement inter-core backup among a plurality of service processing cores in the multi-core processor so as to transmit services of a failure service processing core to a service processing core in backup with the failure service processing core for processing when the service processing core fails and improve the failure recovery speed. The multi-core processor comprises a control core, one or more data transmitting cores, at least two service processing cores and a data output core,wherein the control core is used for transmitting data transmission control information to the data transmitting cores when the failure service processing core is determined; the one or more data transmitting cores are used for transmitting a plurality of data packets to be transmitted to the failure service processing core to a plurality of service processing cores which are backup cores with the failure service processing core according to the data transmission control information; the at least two service processing cores are used for processing the data packets transmitted by the data transmitting cores; and the data output core is used for outputting the received data packets.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for realizing inter-core backup in a multi-core processor. Background technique [0002] At present, due to the strong processing capability of multi-core processors, multi-core processors are more and more widely used in communication equipment, but the existing multi-core processors cannot realize inter-core backup (inter-core backup refers to multiple completions in multi-core processors). The cores with the same function are mutual backup cores), therefore, when a single core fails, the entire multi-core processor needs to be reset to recover from the failure. reliability. [0003] There are following technical defects in the multi-core processor in the prior art: [0004] (1) When a single core in a multi-core processor fails, it is necessary to reset the multi-core processor CPU to achieve fault recovery, which takes a long time; [0005] (2) The multi-core ...

AI Technical Summary

Problems solved by technology

[0004] (1) When a single core in a multi-core processor fails, it is necessary to reset the multi-core processor CPU to achieve fault recovery, which takes a long time;

[0005] (2) Multi-core processors do not follow a certain software architecture during software development, and it is difficult to add inter-core backup functions later
