Abstract
A dual-symbol arithmetic coder architecture with reduced memory is presented for JPEG2000. Eight process elements are used for the prediction of probability interval A. And the use of a dedicated Probability Estimation Table decreases the internal memory greatly. Upon FPGA synthesis results, the architecture´s throughput can reach 96.60M context symbols per second with an internal memory size of 1509 bits.
