Analysis of scalable architecture for the embedded block coding in JPEG 2000
In this paper, the scalable architecture of the embedded block coding (EBC) in JPEG 2000, the bit-plane parallel EBC, is proposed. We provided the analysis and an unified design methodology for the bit-plane parallel EBC architecture. To design the bit-plane parallel EBC, there exists three critical difficulties. To overcome the difficulties, three algorithms are proposed. By use of the proposed algorithms, the external bandwidth of the EBC is reduced by 55% averagely, and the throughput of a 4 bit-planes parallel EBC is higher than a word-level EBC with 10 bit-plans parallel by 1.5 times at the bitrate of 1 bits per pixel
