Novel Word-Level Sequential Scheme and Parallel Architecture For Bit Plane Coding in JPEG2000

This paper presented an improved word-level sequential scheme and parallel architecture for bit plane coding of EBCOT used in JPEG 2000. The bit plane coding adopted by EBCOT is divided into two stages: coding pass prediction and context formation, which work in parallel and pipelined. Word-level and sequential bit plane coding could be achieved that coefficient bits modelling in different bit plane are performed concurrently and, all three passes coding included in each bit plane are completed in one scan. Experimental result demonstrates that the proposed architecture could efficiently reduce hardware complexity, compared to the up-to-date design
