| Abstract(in English) | To fully use an advantage of the dynamic voltage and frequency scaling (DVFS), a fast motion estimation (ME) algorithm called adaptively assigned breaking-off condition search (A^2BCS), and an ME processor that employs both A^2BCS and DVFS were developed. The 90-nm CMOS ME processor consists of an absolute difference accumulator and a small DC/DC converter. Power dissipation of the ME processor was 126.9～161.9μW when ME processes at 384kbps, 15fps, p of 10 pixels were carried out using A^2BCS for various CIF test video pictures. It was about 13.36～17.04% that of the ME processor adopting a well known full search ME algorithm. |
