| Abstract(in English) | A motion estimation (ME) processor that employs dynamic voltage and frequency scaling (DVFS) was developed using a 90-nm CMOS technology. To fully use an advantage of DVFS we developed a fast motion estimation algorithm that was called adaptively assigned breaking-off condition search (A^2BCS). The A^2BCS algorithm can calculate the amount of signal processing from which the minimum clock frequency and corresponding the minimum supply voltage are estimated. The ME processor, that consists of absolute difference accumulator, a minimum value detector, a DVFS controller, PLL clock generator and a small DC/DC converter, occupies a 330 μm×970 μm silicon area. Power dissipation of the ME processor varies from 17.33 to 44.32 μW depending on test video pictures that was from 7.11 to 17.42% power dissipation of a conventional ME processor. |
