High-Speed and Low-Power IP for Embedded Block Coding with Optimized Truncation (EBCOT) Sub-Block in JPEG2000 System Implementation

In this paper we propose novel high-speed and low-power architecture for the context formation sub-block in tier-1 block of JPEG2000 system. The proposed architecture is inspired from the statistical analysis results on 20 test images, each one 512*512 pixels, gray scale with 8 bit pixels. The proposed architecture incorporates a check unit to detect unnecessary operations in both pass1 and pass2 of the EBCOT block. For code block size of 64*64 bits, the timing and power consumption analysis show that the proposed architecture reduces the power consumption about 20.64% and increases the processing speed to about 33.67% with respect to the speedy reference architecture. The proposed architecture has a processing speed close to the parallel mode architectures with almost the same area for serial mode architectures and more power saving. The proposed architecture gathers the basic advantages of the serial and parallel mode implementations in addition to lower power consumption. Ramy E.
