Paper Abstract

The paper presents a context-based arithmetic coder's VLSI architecture used in SPIHT with reduced memory, which is used for high speed real-time applications. For hardware implementation, a dedicated context model is proposed for the coder. Each context can be processed in parallel and high speed operators are used for interval calculations. An embedded register array is used for cumulative frequency update. As a result, the coder can consume one symbol at each clock cycle. After FPGA synthesis and simulation, the throughput of our coder is comparable with those of similar hardware architectures used in ASIC technology. Especially, the memory capacity of the coder is smaller than those of corresponding systems.
