An interconnect interface for reconfigurable multimedia system

This paper propose an efficient interconnect interface, which has been applied in reconfigurable multimedia system (REMUS). In order to achieve high performance of data share between multi cores, this interconnect interface applies overlapping operation mechanism in memory. Test of H.264 HiP (High Profile) decoding shows that the data exchange rate achieves a speedup of 285% compared with the AHB external memory, and the decoding can achieve a speed up of 12.0%. With the support of this competitive work, REMUS could achieve 1080p@30fps of H.264 HiP decoding when it works at the frequency of 200 MHz. This work is tested on the platform of SOC designer 7.1.
