Abstract :
By partitioning a hardware design into several blocks and adjusting the voltage of the different blocks individually, an overall power consumption reduction is possible. An algorithm and a hardware solution for assigning two supply voltages to a design divided into blocks is presented. The two supply voltages are optimized using an on-chip controller. The on-chip controller assigns one of the two supply voltages to each block. This defines a solution suitable for reconfigurable designs
