Bit-plane and pass dual parallel architecture for coefficient bit modeling in JPEG2000

In this paper, the bit-plane and pass dual parallel architecture for coefficient bit modeling in JPEG2000 is proposed. It is a very high speed and efficient structure that is capable of encoding all bits of the wavelet coefficient in only one scan, and largely decreases the memory requirement. Additionally in order to decrease the logic circuit requirement we propose a partial primitive-parallel technique to replace the whole channel-parallelism. Experimental results show that the architecture can encode about 15 times more than the pass-parallel encoding for the coefficient with 16 bits. And it only requires 3K bits memory instead of 16K bits for the pass-parallel encoding.EI
