Abstract
A power scaling unit (PSU) of an electronic system is provided. The PSU includes a software programming interface (SPI) and a PSM. The SPI receives a transaction through software programming. The PSM receives the transaction from the SPI and controls a power driving element (PDE) of the electronic system to change an output of the PDE provided to a function unit of the electronic system according to the transaction. The output of the PDE is an operating voltage or an operating clock signal of the function unit. The transaction includes a command defining a power scaling operation to be performed by the PSM, a parameter used by the operation, and an event mask specifying an event which triggers the operation.
