Abstract :
This paper proposes a new architecture for embedded block coding with optimized truncation (EBCOT) encoder in JPEG2000. As part of a JPEG2000 encoder embedded system under development, it is a parallel mode coder utilizing both code-block and bit-plane parallelisms. In low bit-rate lossy coding, the proposed architecture is roughly two times faster than the fastest existing EBCOT encoder in literature at similar hardware cost and also shows its advantages on memory efficiency, bandwidth requirement and scalability.
