Memory Access Reduced Software Implementation of H.264/AVC Sub-pixel Motion Estimation Using Differential Data Encoding


We studied an efficient software implementation of H.264/AVC sub-pixel motion estimation (ME) algorithm on a VLIW-SIMD digital signal processor, TMS320C6416. The sub-pixel ME algorithm demands large memory accesses while the required arithmetic operations are fairly simple. Although the CPU clock cycles for arithmetic operations can be reduced much by… (More)
