CAVLC is a essential data path of H.264 image compression codec. This block is combined with and receives data from a transform block, but both block have different processing order. In CAVLC block, parameter extraction is the key process to reduce processing cycles and enhance the throughput. This paper suggests a new architecture that combines scan process with CAVLC parameter extraction function. Suggested ideas reduce areas and make the function work with low operation frequency. This work designed by Verilog HDL and implemented with TSMC 0.18um process.
