A Low Cost design for Optimized IDCT and de-quantization of H.264

H.264 also known as MPEG4 part 10 is a promising video coding standard for the next generation video compression. To meet the needs of low cost H.264 decoders, this paper presents a low cost hardware implementation for the improved IDCT (inverse discrete cosine transform) and de-quantization of H.264. For the tradeoff between areas and processing speed, this hardware implementation achieves real-time decoding for all available video resolution formats at a quite low area cost
