Analysis and VLSI High Speed of Parallel Causal EBCOT Architecture for Image Compression

Embedded block coding with optimized truncation (EBCOT) is a key algorithm in digital cinema (DC) distribution system. Though several high speed EBCOT architectures exist, all are not capable of meeting the DC specifications. With the augmentation in multimedia technology, demand for high speed real time image compression system has also increased. JPEG2000 is a relatively new image compression standard which builds and improves on its predecessor JPEG. In Jpeg 2000 the embedded Block Coding with Optimal Truncation (EBCOT) is the most important element to calculate the very hard portion in the compressing process of JPEG 2000 image compression standard. This paper proposes a Parallel Bit Plane Coding (BPC) architecture in which three coding passes operate in parallel and are allowed to progress independently.
