A case study on MPEG4 decoder design with SystemBuilder

Abstract

This paper presents a case study on designing an MPEG4 decoder system using our system-level design toolkit named SystemBuilder. We start with a sequential specification of the MPEG4 decoder behavior and generate an FPGA implementation. In order to improve the performance, we refine the behavioral description based on the analysis result obtained by a profiler. Finally, we achieve over 15fps performance with pipelined hardware implementation.
