内容記述 |
This paper describes a sub-mW motion estimation processor core for MPEG-4 video encoding. It features a gradient descent search (GDS) algorithm that reduces required computational complexity to 15 MOPS. The GDS algorithm combined with a sub-block search method upgrades picture quality. The quality is almost equal to that of a full search method. An SIMD datapath architecture optimized for the algorithm decreases a clock frequency and supply voltage. A dedicated three-port SRAM macro for image data caches of the processor is newly designed to reduce power consumption. It has been fabricated with 0.18-/spl mu/m five-layer metal CMOS technology. The VLSI processing QCIF 15-f/s video consumes 0.4-mW power at 0.85-MHz clock frequency with 1.0-V supply voltage. It is applicable to mobile video applications. |
