Statistically optimized VLSI architecture for buffer for EBCOT in JPEG2000 encoder

Abstract

In this paper we present the VLSI architecture for the buffer for tier-I of EBCOT encoder of JPEG2000. The buffer allows the integration of bit-plane coder and arithmetic coder module employing concurrent symbol processing technique. The buffer architecture is optimized by exploiting the natural image statistics to optimally choose the buffer length parameter. The overall architecture is implemented using Altera FPGA and experimental results show a savings of 59% in the hardware cost with minimal reduction in the overall throughput.
