Abstract

Abstract

EBCOT algorithm is an essential part of the new image compression standard, JPEG2000. The Tier1 part of EBCOT requires each bit-plane be scanned for three times in order to generate entropy contexts. Therefore the scanning efficiency is unacceptable，which fails to fulfill real-time compression of high quality images. So far some improvements have already been made, mainly based on PS/GOCS, and multi-window/pass-parallel coding technique. In this paper, a hardware-oriented, full pass-parallel coding architecture is presented, based on only one scanning window. This architecture is verified on FPGA. Experimental results show that its coding speed is superior to the other two main improvements. Furthermore, the coding logic adopted can be reused on the decoding stage, which facilitates sharing code/decode architecture.
