A feed-forward dynamic voltage frequency management for power-minimum motion video compression in sub-decimicron era

In this paper, a feed-forward dynamic voltage frequency management method for power-minimum motion video compression is described. This method, which controls operating voltage/frequency and body bias voltage of a RISC processor, reduces power consumption of software based video compression processing. The SPICE simulation indicates that the proposed method reduces 82% to 65% or power consumption depending on the characteristics of input sequences.
