Title: POWER MANAGEMENT USING DUTY CYCLES
Abstract:
An integrated circuit (IC) is disclosed herein for power management using duty cycles. In an example aspect, the integrated circuit includes multiple power domains, each of which includes a respective power state controller. The power state controller acts as a bridge between global supply lines of the integrated circuit and local supply lines of the respective power domain. Global supply lines can include a first global power rail, a second global power rail, and a global clock tree. Local supply lines can include a local power rail and a local clock tree. In operation, a power state controller adjusts a power state of the respective power domain in accordance with a duty cycle. A timeslot corresponding to the duty cycle can be separated into multiple time periods with durations of the time periods being based on the duty cycle.
