(English Abstract)
Recently, the SoC industry mainly uses various multi-layered bus architectures. However, reckless use of bus layers may results in on-chip communication resources and waste of silicon area. This paper performs a quantitative analysis to compare the two de-facto on-chip buses and SNP. Through the performance estimation, the performance of SNP turns out to be significantly enhanced for asymmetric write and read traffic (non-central F distribution) while symmetric traffic is similar to that of AXI. More specifically, SNP properly places IP cores on the top or bottom, induces the write and read channels to be balanced, and achieves about twenty percent improved performance compared to AXI.
