High-throughput MQ encoder for pass-parallel EBCOT in JPEG2000

This paper proposed a high throughput MQ encoder for pass-parallel EBCOT. Proposed MQ encoder can encode CX-D pairs from mixed three passes. A new extended probability estimation table (PET) is proposed. By looking up to the PET, register A can get the total shift times during renormalization. A pipelined auxiliary unit is also used in BYTEOUT procedure to minimize the critical path. Proposed MQ encoder can encode one symbol per clock cycle. It is implemented on a Xilinx FPGA and is capable of operating at 139.09MHz. It can achieve a throughput of 139.09Msymbols/sec.
