Abstract
Dynamic Power Management and Dynamic 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 VHDL. Simulations in the MATLAB environment and in ModelSim have allowed the validation of the control technique proposed. Being synthesized in technology FD-SOI 28nm using RC synthesis tool from Cadence, the control method presents only 10.8% of Silicon area overhead with 1.6% of power consumption reduction. This preliminary result is appealing because it has been obtained without voltage scaling that will improve the power gain even more.
