Abstract

JPEG2000 is the latest still image coding standard. It was designed to overcome the limitations of the original JPEG standard and provide high quality images at low bit rates. The JPEG2000 algorithm is fundamentally based on the Discrete Wavelet Transform (DWT) and Embedded Block Coding with Optimal Truncation (EBCOT). Both of the algorithms are computationally intenstive and require significant memory bandwidth. In this paper we propose a JPEG2000 hardware/software co-processing architecture that complements existing JPEG2000 software packages with efficient dedicated hardware units for EBCOT tier-1 coding, enabling significant speedup.
