| Abstract(in English) | To reduce power dissipation of an absolute difference accumulator (ADA) for MPEG-4 motion estimation (ME), a fast ME algorithm called a "Breaking-Off-Search Adaptively minimizing number of block matchings (BOSA)" algorithm was developed. BOSA can improve processing speed of the full-search (FS) method by a factor of more than 11, depending on picture types, while maintaining visual quality of the FS method. At clock frequency of 160 MHz and supply voltage of 1.4V the power dissipation of a 0,18-μm CMOS ADA using BOSA and a gated-clock pulse scheme was reduced to 35.4μW that was about l/11.76 that of the same ADA implementing FS. |
