The DVS 926 CPU provides an integrated solution for addressing power management of SoC devices. The SoC includes the main components of mobile handheld devices along with multiple voltage domains. This new methodology is used to EDA Tools for using soft-IP in multiple frequency-and voltage domain designs. This is the standard interface to on- and off-chip power supplies and controls the processor's performance levels. The SoC software algorithms are derived the minimum sufficient performance for running dynamic workloads.
