High Speed Multiple Word Parallel Architecture for Bit Plane Coding used in JPEG 2000

This paper presented a high speed multiple word parallel architecture (MWPA) with sequential coding for fractional bit plane coding used in JPEG 2000, where all bit planes are coded in parallel, and all bit samples in the same bit plane are coded in sequential. The proposed MWPA adopts a technique of performing the coding pass prediction and context formation in parallel and pipelined fashion, thus context formation for a column of 4 coefficients could be achieved in each intra-clock cycle, and multiple passes coding of fractional bit plane coding are completed by one scan. Theoretical analysis and experimental results demonstrate that, the proposed MWPA could significantly increase throughput rate with good performance in terms of speedup to cost, compared with the previous works
