Problems solved by technology

Although the transmission overhead of the retransmission mechanism is relatively small, it is necessary to set up a data cache area separately in the on-chip network to back up the data packets, especially in the process of transmitting a large amount of data, which increases the resource consumption of the on-chip network, and when an instantaneous When a fault occurs, the data packet needs to be resent, which increases the data transmission delay

Abstract

This application discloses a data processing system including on-chip network fault-tolerant routing. The data processing system includes: a data receiving module and a routing fault-tolerant module; Write it as source data, send the source data to the routing fault-tolerant module; the routing fault-tolerant module is used to transmit the source data simultaneously according to the first transmission path and the second transmission path after establishing the first transmission path and the second transmission path according to the preset routing rules to an external processing device. Through the technical solution in this application, the transmission delay and transmission overhead in the data routing process are reduced, the fault tolerance in the data routing process is improved, and it is beneficial to realize high reliability transmission of data.

Description

technical field [0001] The present application relates to the technical field of aerospace information processing, in particular, to a data processing system including an on-chip network fault-tolerant routing. Background technique [0002] Outside the atmosphere, electronic equipment is exposed to a strong radiation environment with a large number of cosmic rays. These cosmic rays are composed of high-energy charged particles such as electrons, protons, and alpha particles. They have strong penetrating ability and are harmful to electronic components in electronic equipment. very prominent. When high-energy charged particles bombard electronic components, it will cause permanent effects or transient effects of electronic components. Among them, the transient effects caused by high-energy charged particles include single-event inversion, single-event transient and multi-bit inversion. When high-energy charged particles bombard electronic components and cause transient effec...
