Abstract

In this paper, a high throughput and memory efficient EBCOT architecture for JPEG2000 in digital camera system is proposed. According to the proposed memory-efficient algorithm, three coding state variables (γp[n] , σp[n],and πp[n]) can be calculated on the fly to eliminate three coding state variable memories. Moreover, three coding passes and four samples within the stripe-column are also performed concurrently by the proposed stripe-column-based pass-parallel operations. The experimental results show that the proposed architecture has 4 times greater throughput than other architectures, and the memory size of the proposed architecture is smaller than other existing architectures.
