Abstract
We present a hardwired decoder prototype for H.264/AVC main profile video. Our hardware functional blocks include variable-length decoding, CABAC decoding, inverse quantization and inverse DCT, motion compensator, intra compensator, and deblocking filter. They communicate with one another via memory buffers and are integrated and controlled by a main controller. The whole decoder is wrapped with an AMBA-AHB wrapper such that it can be reused as a silicon IP. We have verified the proposed design in FPGA prototype. Running at 30MHz, it is capable of real-time decoding GIF video @ 30fps.
