MUX-MCM based quantization VLSI architecture for H.264/AVC high profile encoder

This paper presents a hardware-efficient and high-throughput quantization implementation for H.264/AVC high profiles encoder. The constant multiplication in quantization is accomplished by time-multiplexed multiple-constant multipliers (MUX-MCM). By rational pipeline decision, the proposed design manages to achieve a high throughput at a low area cost. Synthesized with SMIC0.18µm technology, the proposed design reaches a maximum operating frequency of 250Mhz with a throughput of 1Gpixels/sec at the hardware cost of 28.56 Kgates.
