Abstract
This paper describes an AMBA-based IP to perform forward and inverse transform and quantization required in the H.264 video compression standard. The transform and quantization circuit was optimized for area and performance. The AHB wrapper was added to the circuit for the AMBA-based operation. The user of the IP can specify how long the bus may be occupied by the IP and also where the video data are stored in the external memory. The function of the proposed IP based on AMBA Specification was verified on the platform board with Xilinx FPGA and ARM9 processor. We fabricated an MPW chip using $0.25{\mu}m$ standard cells and observed its correct operations on silicon.
