Scalable Rate-Distortion-Computation Hardware Accelerator for MCTF and ME
Motion-compensated temporal filtering (MCTF) is an innovative prediction scheme for video coding and the core technology of scalable extension of H.264/AVC. The first MCTF and ME hardware work is in this paper. The proposed hardware not only can support the various coding schemes in JSVM and H.264 but also can adapt itself to provide rate-distortion-computation scalability. With the frame-level searching range data reuse and frame-interleaved MB pipelining scheme, external memory bandwidth are reduced 33%, and 10 Kbits buffer are saved. The proposed MCTF/ME hardware is of 350K gate counts and 30 KB internal buffer, which can perform four-level MCTF or H.264 P-/B-frames at CIF format
