Abstract

In this paper we described the architectural exploration of Star-Mesh NoC based multi-channel H.264 decoder. The Star-Mesh NoC is comprised of local star switch and global mesh switch. By analyzing data transfers among the processors, IPs, and memories, we partitioned IPs into clusters to map then to Star-Mesh NoC architecture. In order to enhance data parallelism and NoC utilization, H.264 decoder IPs with much data traffic are mapped to star switch and shared memory is connected to mesh switch where star switch connected to mesh switch with 1-hop. We explored several mapping architecture to achieve improvement of the system throughput.
