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...
In this paper, a design of a dual symbol processor for arithmetic coder architecture implemented on FPGA is proposed. Usually, the regular operation of the MQ-Coder is sequential, which can process only one symbol at a time. However, the bit-plane coding can generate more than one symbol per clock cycle. Consequently, the coding speed will be limited and bottlenecked at the interface between the output...
