To fulfill the computing demands in visual media processing, we have been investigating a parallel processing system to improve the processing speed of the visual media related to applications from the point of view of a memory system within a single instruction multiple data (SIMD) computer. In this paper, we have introduced MAMS-PP4, which is similar to a pipelined SIMD architecture type and consists of pq processing elements (PEs) as well as a multi-access memory system (MAMS). MAMS supports simultaneous access to pq data elements within a horizontal (1 × pq), a vertical (pq × 1) or a block (p × q) subarray with a constant interval in an arbitrary position in an M × N array of data elements, where the number of memory modules, m, is a prime number greater than pq. MAMS reduces the memory access time for an SIMD computer and also improves the cost and complexity that involved in controlling the large volume of data demanded in visual media applications. PE is designed to be a two-state machine in order to utilize MAMS efficiently. MAMS-PP4 was fabricated into ASIC using TOSHIBA TC240C series library and a test board was used to measure the performance of ASIC. The test board consists of devices such as an MPC860 embedded-PCI board, two ASICs and a FPGA for the control units. Experiment was done on various computer systems in order to compare the performance of MAMS-PP4 using morphological operations as the application. MAMS-PP4 shows a respectful and consistent processing speed.
