Abstract
A method for simplifying the host-to-display subsystem communications and consolidating the non-volatile memory requirements into a PMIC (power management integrated circuit) is disclosed. Hardware and software resource reduction in both the client devices (located in the display subsystem) and the host System on a Chip (SOC) can be realized with a novel PMIC design. The novel PMIC design achieves the resource reduction by providing for the following features: (1) Single-point communication, (2) Single-point notification, (3) Client device status storage, (4) Client device initialization from PMIC non-volatile memory, and (5) Subsystem calibration retrieval from PMIC non-volatile memory.
