Efficient Memory Organization and Data Transfer Technique for DWT- EBCOT Integration of JPEG2000

JPEG2000 is a new image compression standard known for its rich set of features, impressive compression performance as well as its complexity for efficient hardware implementation. Discrete Wavelet Transform (DWT) and embedded block coding with optimal truncation (EBCOT) are two main modules in JPEG2000 compression system. Data transfer between DWT and EBCOT plays a key role in deciding the overall power consumption cost of a JPEG2000 hardware system. In this paper, we investigate data transfer and storage techniques between DWT and EBCOT modules. We propose an efficient memory organization scheme and data transfer technique to reduce data bandwidth. Simulation results show that our proposed techniques result in approx. 3 times less bandwidth per EBCOT module.
