Decision support systems Power management FIFO-level-based PI controller H.264 encoder
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 ...
