【Abstract】 A design and implementation of reconfigurable stream processor applied in multimedia filed are proposed. Based on the unique parallel stream processing framework and optimized algorithm mapping method, the approach exploits the parallelism of complex algorithms and provides a high flexibility during run-time to adapt to various applications. The prototype of this processor is implemented and verified on Virtex4. Combined with the ARM9 processor, the embedded multimedia processing platform is realized, and thus the dacoding processing in H.264 and AVS are verified.更多还原
