Abstract
We can integrate more IP blocks on a silicon die as the development of fabrication technologies and EDA tools. Consequently, we can design complicated SoC architecture including multi-processors. However, most of existing SoC buses have bottleneck in on-chip communication because of shared bus architectures, which result in the performance degradation of systems. In most cases, the performance of a multi-processor system is determined by efficient on-chip communication and the well-balanced distribution of computation rather than the performance of the processors. We propose an efficient SoC Network Architecture(SNA) using crossbar routers which provide a solution to ensure enough communication bandwidth. The SNA can significantly reduce the bottleneck of on-chip communication by providing multi-channels for multi-masters. According to the proposed architecture, we design a model system for the SNA. The proposed architecture has a better efficiency by $40\%$ than the AMBA AHB according to a simulation result.
