Abstract
In this paper, we present an MPEG-2 video decoder implemented in our ODYSSEY design methodology. We start with an ASIP tailored to the JPEG decompression algorithm. We extend that ASIP by required software routines such that the extended ASIP can now perform MPEG2 decoding while still benefiting from hardware units common between JPEG and MPEG2. This demonstrates the ability of our approach in extending an already manufactured ASIP, which was tailored to a given application, such that it implements new, yet related applications. The implementation platform is a VirtexII-Pro FPGA. The hardware part is implemented in VHDL, and the software runs on a PowerPC processor. Experimental results show...
