High performance IPC hardware accelerator and communication network for MPSoCs

In this paper, we explain a configurable IPC module for multimedia MPSoCs, which was implemented in a MPW chip that include three ARM7 CPU cores. According to the test results for an M-JPEG and a H.264 decoder, its IPC synchronization overheads are not more than 1% when the synchronization period is about 5000 cycles.
