Soft-core reduction methodology for SIMD architecture: OPENRISC case study

Multi-Processor Systems on Chip (MPSoCs) have been proposed as a promising solution for the increasing demand of computational power required for recent application. The parallelization through SIMD (single instruction/multiple data) architectures has been a proven solution to speed up the processing of the recent application that exhibit massive amounts of data parallelism. The level of parallelism impacts the SIMD architecture performance and it is closely related to the design of the processing element. In this context this paper presents a new design methodology of designing processing element for SIMD architecture. The scope of this work is to reduce the pipeline stages of the soft-core processor to reduce the size of the PEs and so that to built up a high level parallelism architecture.
