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.

본 논문은 H.264 비디오 압축 표준에서 필요로 하는 순방향 및 역방향 변환과 양자화를 수행할 수 있는 AMBA 기반 IP에 대해서 기술하고 있다. 변환과 양자화 회로는 면적과 성능 측면에서 최적화되어 있으며, AMBA를 기반으로 동작하기 위해서 AHB 랩퍼 회로가 추가되었다. IP가 버스를 점유하는 시간과 비디오 데이터를 외부 메모리의 어느 위치에 저장할 것인지를 사용자가 지정할 수 있도록 설계하였다. Xilinx FPGA와 ARM9 프로세서를 장착한 플랫폼 보드를 사용하여 제안된 IP가 AMBA 표준에 근거하여 동작하는지를 검증하였다. $0.25{\mu}m$ 표준 셀을 사용하여 이 회로를 MPW 칩으로 제작하고 동작을 확인하였다.
