High-speed EBCOT with dual context-modeling coding architecture for JPEG2000

This work presents a parallel context-modeling coding architecture and a matching arithmetic coder (MQ coder) for the embedded block coding (EBCOT) unit of the JPEG2000 encoder. The tier-1 of the EBCOT consumes most of the computation time in a JPEG2000 encoding system, and the proposed parallel architecture can increase the throughput rate of the context-modeling. To match the high throughput rate of the parallel context-modeling architecture, and efficient pipelined architecture for context-based adaptive arithmetic encoder is proposed. This encoder of JPEG2000 can work at 185MHz to encode one symbol each cycle. Compared with the conventional context-modeling architecture, our parallel architecture can decrease the execution time about 25%.
