지연시간 효율 개선을 위한 On-Chip Network 구조 설계 및 구현

초록

As increasing the number of IPs integrated in a single chip and requiring high communication bandwidth on a chip, the trend of SoC communication architecture is changed from bus- or crossbar-based architecture to packet switched network architecture, NoC. However, highly complex control logics in routers require multiple cycles to switch packet. In this paper, we design low complex router to improve the communication latency. Our NoC design is verified by simulation platform modeled by ESL tool, SoC Designer. We also evaluate our NoC design comparing to the previous NoC architecture based on VC router. Our results show that our NoC architecture has less communication latency, even small throughput degradation (about 1-2%).
