Abstract: Methods and apparatus for implementing a Dynamic Voltage Scaling (DVS) system are presented herein. In one embodiment, an embedded delay checker (EDC) cell is used to measure the actual activity and delay of a critical path within a microprocessor core, which is the basis for dynamically altering the voltage to the core. In another embodiment, a slaved ring oscillator (SRO) cell is placed adjacent to the microprocessor core and is used along with EDC cells to provide redundancy to a DVS system.
