Chip Multi-processor System based on Cardinal Bidirectional Ring Network-on-chip

Abstract

This Cardinal 4-core chip multi-processor system is implemented based on Cardinal processor with 32-bit address and 64-bit data and Cardinal 4-node ring NoC which supports packet (VCT or wormhole) switching. Cardinal NiC is short for network interface components that can be used to simplify packets changing between ring NoC and processors. Each register or buffer of NiC can be accessed using 2-bit memory address so memory instructions (LD or SW) can be used to access NiC and make it possible to transfer messages between different IP cores.
