STUDY AND DESIGN OF I)lREC'l‘ MEMORY ~ ACCESS CON'I‘R()LLER

Abstract

Abstract The problem oftime consuming in data transfer in computer-based systems is of great importance, especially in systems that need last response. Computer engineers think ofa device that decreases this time consumption as much as possible, they find that the direct memory access concept is one olithe best ways this problem could he solved. The direct memory access controller is a device that allows data to flow directly between thc memory and peripheral devices. thus decreasing the time consumption.
