VLSI architecture for MQ coder in JPEG2000

The embedded block coding with optimized truncation (EBCOT) is a key algorithm in JPEG2000 image compression standard. The matrix quantizer (MQ) coder used in this algorithm restricts throughput of the EBCOT because feedback loop operations are iterative. To overcome this we use phase shift clocks to update registers used in MQ coder. The proposed architecture is implemented on Virtex-5 Xilinx FPGA.
