Abstract

Multimedia devices demands a platform integrated various functional modules and an increasing support of multiple standards. Stream architecture is able to solve the problem. However the applications suited for typical stream architecture are limited. This paper describes MASA (Multiple-morphs Adaptive Stream Architecture) prototype system which supports regular stream and irregular stream by different execution models according to applications’ stream characteristics. The paper first discusses MASA architecture and stream model, and then explores the features and advantages of MASA through mapping a stream applications H.264 to hardware. The result is encouraging. At last, presents the design and implementation on FPGA of MASA’s prototype.
