Abstract

This paper describes work at the University of Sussex in the field of multimedia video and high resolution display control. This paper is the result of research carried out for the SMILE (SPARC Macrocell and Interface Library Elements) project, one of the coordinated set of projects within Esprit III. The overall objective of SMILE is to develop, within the Open Microprocessor systems Initiative (OMI) framework, a family of SPARC based library cells, both 32-bit processor-core and application-oriented, to provide the basis for a next generation family of microprocessors/controliers that give the European systems industry a collective edge. The University of Sussex is required to design a system that provides 2-D graphics functions to support full motion video, image transformation and high resolution display control. In this paper we describe the approach taken in employing classic memory interleaving techniques together with an innovative memory access coordination approach and dedicated video hardware to provide a high bandwidth frame store, optimised for live video support.
