Efficient pass-pipelined VLSI architecture for context modeling of JPEG2000
Khomkris Mathiang, Orachat Chitsobhuk · 2007
In this paper, a design of pass-pipelined architecture for context modeling implemented on FPGA is proposed. The architecture is separated into 4 pipelined stages. As a result, the processing time and the critical path delay can be reduced while the multiple symbol context pairs are allowed to be generated simultaneously. Moreover, dual memories and data multiplexer are employed in order to accelerate the memory access. The proposed pass-pipelined architecture can process with the speed greater than 100 MHz and can generate up to 22 context-data pairs in one clock cycle.
