FIFO-level-based Power Management and its Application to an H. 264 Encoder

Abstract

Voltage and Frequency Scaling have been investigated during the last decades to reduce the power consumption of electronic circuits and systems. This paper proposes a new implementation of dynamic frequency scaling to manage the power consumption based on the occupancy level of a FIFO in a communication link between two components. Based on control theory, the method is simple and application independent. The PI controller proposed here was first tested in the MATLAB environment and then designed using ...
