Cost-effective low-power architectures of video coding systems
A new low-power design technique, multirate, has been used along with other methods such as look-ahead and pipelining in designing the cost-effective low-power architectures of video coding systems. We demonstrate both low-power and high-speed can be accomplished at algorithm/architecture level. Based on the calculation and simulation results, the design can achieve significant power saving in the range of 60%-80% or speedup factor of two depending on the needs of users.
