Abstract

Abstract:

The MQ encoder has become the bottleneck of the improvement of the performance of JPEG2000 coding because of its serial processing nature. This paper presents a high efficient MQ encoder for the JPEG2000 image compression system. Index prediction and some other optimization technique have been used to shorten the encoding time and reduce required memory. Besides, in order to apply the efficient MQ encoder into the Tier1 encoder, a new design for realizing the interface between BPC encoder and MQ encoder is also presented based on the output characteristics of BPC and the throughput of the Tier 1 encoder can be raised up to three times. The MQ encoder is synthesized on FPGA, and it can achieve at least 10％ throughput increase compared to the existing structure. The required memory has also been reduced obviously.

Key words: JPEG2000, Tier 1 encoder, MQ encoder, very large scale integration circuits
