Robust and efficient dynamic voltage scaling architecture [microprocessor based systems]

An efficient dynamic voltage scaling (DVS) architecture to track process and temperature, based on a lookup table, is presented. If environmental conditions change faster than the DVS system can track, the supply voltage must be raised to satisfy the worst case process and temperature conditions. In the proposed system, an efficient method of identifying the process is used, independent of temperature conditions. Voltage can be adjusted, based on the split information extracted. The proposed system can achieve up to 29% energy savings compared to the conventional system.
