SIMD Computer Using 16 Processing Elements for Multi-Access Memory System
Improving the speed of image processing is in great demand according to spread of high definition visual media or massive images applications. A Single Instruction Multiple Data (SIMD) computer attached to a host computer can accelerate various image processing and massive data operations. Especially, MAMS (Multi-access Memory System) can not only reduce the access time of the memory but also improve the cost and complexity for the large volume of data demanded in visual media applications. This paper presents implementation of simulator for image processing algorithms and speed comparison of an SIMD architectural multi-access memory system, MAMS-PP16 which consists of MAMS and 16 processing elements (PEs), executed with MAMS-PP4 which consists of MAMS and 4 processing elements(PEs). The newly designed MAMS-PP16 has a 64 bits instruction format and application specific instruction sets. The result of performance analysis verifies performance improvement and the consistent response of MAMS-PP16 through the morphology filter operation in image processing algorithms, comparing with a CISC-based(Intel Processor) Serial Processor.
