Abstract

In this paper, we propose H.264 High Profile Encoder Intra Prediction module. This designed module can be operated in 306 cycle for one-macroblock. To verify the Encoder architecture, we developed the reference C from JM 13.2 and verified the our developed hardware using test vector generated by reference C. We adopt plan removal and SAD calculation to reduce the Hardware cost and cycle. The designed circuit can be operated in 133MHz clock system, and has 250K gate counts using TSMC 0.18um process including SRAM memory.

본 논문에서는 AMBA 기반으로 사용될 수 있는 H.264용 High Profile IP를 제안한다. 설계된 모듈은 한 매크로 블록 당 최대 306 cycle내에 동작한다. 제안된 Encoder 구조를 검증하기 위하여 JM 13.2부터 reference C를 개발하였으며, reference C로부터 test vector를 추출하여 설계 된 회로를 검증하였다. 우리는 Hardware cost를 줄이기 위하여 plan mode를 제거하였고, SAD 계산 방법을 사용하여 Hardware cost와 cycle을 줄이는 방법을 채택하였다. 제안된 회로는 133MHz clock에서 동작하며, 합성결과 TSMC 0.18um 공정에 램 포함 25만 gate크기이다.
