In this paper, we present a JPEG decoder implemented in our ODYSSEY design methodology. We start with an object-oriented JPEG decoder model. The total operation from modeling to implementation is done automatically by our EDA tool-set in about 10 hours. The resultant system is a JPEG decoder ASIP whose hardware part is implemented on FPGA logic blocks and software part runs on a MicroBlaze processor. This ASIP can be extended by software routines to implement the motion JPEG or MPEG2 decoding algorithms. We implemented our system on ML402 FPGA-based prototype board. Experimental results show that our ASIP implementation is comparable to other approaches while our approach enables quick and easy development of an ASIP using our EDA tool-set and effectively reduces time-to-market.
