A Novel on-Chip Communication Data Channel Architecture Used in USB2.0

ZHOU Wei,HUANG Hong,ZHOU Xiao-fang,SUN Cheng-shou(ASIC & System State Key Laboratory,Fudan University,Shanghai 201203,China)  
A novel architecture of data channel for on chip communication used in USB 2.0 device controller integrated to SoC is proposed.Through dynamic allocating and reclaiming limited channel buffer resource on runtime,channel throughput is obviously improved without obviously increasing RAM size.This novel channel architecture has been successfully applied to home network SoC platform.Testing result shows that compared to traditional channel architecture the present architecture has improved the throughput by 63% in average; meanwhile the average usage ratio of buffer resource of more than 95% has been obtained.
