SDRAM controller for real time digital image processing systems

Abstract

Nowadays, a lot of modern digital systems are based on processor-memory architecture. Additionally, when large capacity and data transfer rate is required, SDRAM memory is used. Moreover, there is a trend to combine multi-chip systems into one device, so called on-chip systems. In such defined systems a built-in SDRAM controller is needed. This paper presents a SDRAM controller adapted to work in fast digital image processing systems. The interface of the controller was simplified to give more flexibility in usage for designers.
