Abstract: RCSIMD is a computer architecture multiple configuration multiple data stream(MCMD), RCSIMD can implement SIMD or MIMD working modes by configuration data controlling. And RCSIMD not only carries out zero configuration delay, but also changes the communication net between one-dimension and two-dimension in one delay cycle, which greatly improves the flexibility of RCSIMD architecture. Multiple application algorithms mapping results show that the architecture of RCSIMD adapts to application of the multimedia and image processing. Based on Charter 0.25μm process standard cell library, the area of processing array(RPA) of the RCSIMD is 7mm×7mm and the critical path delay of RPA is 16 ns.
