ABSTRACT:
A power island for a system-on-a-chip (SoC) includes a first segment, a second segment, and a supply line. The first segment includes a hardware device and operates the hardware device at first power characteristics indicative of at least a first voltage. The second segment includes scalable logic and operates the scalable logic at second power characteristics indicative of at least a second voltage. The second power characteristics of the scalable logic are different from the first power characteristics of the hardware device. The supply line receives an external supply signal (VDD) and directs the external supply signal to both the first segment and the second segment. The second segment changes at least one power characteristic of the external supply signal to operate the scalable logic according to the second power characteristics.
