Abstract(in English) | The MX core is a massively parallel SIMD (Single Instruction Multiple Data) processor based on fine-grained 1,024 PEs (Processing Elements). This is developed by Renesas technology corp., achieves high performance for multimedia processing. However, due to its SIMD structure, the MX core has a larger PE communication cycle overhead under complicated condition such as deinterleave operation. In order to overcome it, we applied MIMD (Multiple Instruction Multiple Data) controlled data communication between PEs. This paper describes a path planning method for MIMD controlled data communication with MX core architecture. We evaluate it using some circuits. As a result, although the number of communication steps is improved by 85% as compared to SIMD type communication, slightly compared to manual mapping methods. |
