Abstract :
This paper proposes a performance-aware transform IP design which can be configured to appropriate hardware for different performance requirements on demand without requiring additional data bandwidth in multimode video coding (JPEG/MPEG-1/2/4/H.261/H.263/H.264). Based on the scalable-DA approach, three schemes of hardware configurations which are respectively composed of 3, 6, and 12 data-paths are illustrated. The three schemes of the proposed performance-aware DCT/IDCT can achieve CIF, 720HD, and digital cinema video formats when operated at 9.13 MHz, 41.48 MHz, and 188.75 MHz, respectively
