Highly reliable network server system on chip and design method thereof

The invention discloses an on-chip network router system with high reliability and a design method thereof, wherein, the design method of the on-chip network router system with high reliability comprises the steps that: a router soft core based on a wormhole routing swap mode and a rotation routing selection mode is designed; a corresponding SCAC coding circuit, an SCAC decoding circuit and an SCAC error correction circuit are designed for data with a specified width; and the SCAC error correction circuit is added into the router; the SCAC coding circuit and the SCAC decoding circuit are connected with the router so as to from a framework of the router system; an SCAC-TMR fault tolerance proposal is designed for the framework of the router system and the on-chip network router system with high reliability is realized; the functions of the on-chip network router system with high reliability are tested and verified and the performance of the on-chip network router system with high reliability is evaluated. The on-chip network router system with high reliability of the invention can reduce the area, the energy consumption and the expenses of the on-chip network, ensure the reliable data transmission of the on-chip network and prevent a signal jumping with a relatively long time delay from appearing on the channel, thus being more applicable to the design of fault-tolerant and multi-core processors in the future.
