Abstract :
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 requirements 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 3 K bits memory instead of 16 K bits for the pass-parallel encoding.
