Abstract
Official abstract text for this publication.
The application discloses a voltage regulation method, and a corresponding HPM, chip, and chip system. The method is used to regulate a working voltage of the chip, which includes an AVS module and at least one HPM. The method includes: outputting, by the AVS module, a clock signal to the HPM; generating, by the HPM, a corresponding pulse signal according to the clock signal and at least performing first delaying for the pulse signal to acquire a first actual output value and performing second delaying for the pulse signal to acquire a second actual output value; and fitting, by the AVS module, the first and second actual output values at least according to weights of the first and second actual output values to acquire a fitting output value and determine, by comparing the fitting output value with a predetermined reference value, whether to regulate the working voltage of the chip.
First claim
Opening claim text (preview).
What is claimed is: 1. A voltage regulation method for regulating a working voltage of a chip, wherein the chip comprises an adaptive voltage scaling AVS module and at least one hardware performance monitor HPM, and the method comprises: outputting, by the AVS module, a clock signal to the HPM; generating, by the HPM, a corresponding pulse signal according to the clock signal, and at least performing, for the pulse signal, first delaying related to a first threshold voltage Vt t…
