Abstract :
Embedded block coding with optimized truncation (EBCOT) consumes more than 50% of the processing time in JPEG200 encoding system. Hardware implementation with careful handling for the control nature of tier-1 is essential. Although, some architectures have been developed to speed up the coding operations, they still require a tedious checking mechanism to decide if each sample is eligible or not for coding. We propose a novel checking scheme for the three coding passes for EBCOT that works in parallel with the encoding process to achieve the required high throughput. The simulation results show that the proposed architecture increases the throughput by 19% on average compared, to other well known architectures.
