Adaptive Techniques for Energy-Efficient Video Processing

Abstract:

The recent explosive growth of portable applications, such as video phones, PDA, digital video cameras, etc., has elevated needs for low-energy video processing hardware and software. This talk will introduce new algorithmic and architectural techniques which can significantly shrink the energy consumption of video coding and decoding tasks. Unlike traditional methods, the techniques exploit picture correlation and input statistics to dynamically adjust the number of operations, memory accesses, operational bit-width and supply voltage to varying picture content. Applications to motion estimation, discrete cosine transform and memory access optimization will be presented. Practical issues and open problems will be outlined.
