Abstract: A method and apparatus for isolating and restoring general-purpose input/output (GPIO) pads in a computer system includes identifying GPIO pads associated with the region responsive to an entry into a power-down state of a region of a circuit. The GPIO pads are isolated from one or more external circuits. Upon exit from the power-down state, each associated GPIO pad is restored to a current value.

Abstract: The described embodiments include an apparatus that controls voltages for an integrated circuit chip having a set of circuits. The apparatus includes a switching voltage regulator separate from the integrated circuit chip and two or more low dropout (LDO) regulators fabricated on the integrated circuit chip. During operation, the switching voltage regulator provides an output voltage that is received as an input voltage by each of the two or more LDO regulators, and each of the two or more LDO regulators provides a local output voltage, each local output voltage received as a local input voltage by a different subset of circuits in the set of circuits

Abstract: Devices and methods for linear addressing are provided. A device is provided which comprises a plurality of components having assigned registers used to store data to execute a program and a power management controller, in communication with the components. The power management controller is configured to send one of a request to remove power to the components and a request to reduce power to the components when it is determined that the components are idle, execute a first process of one of removing power and reducing power to the components and entering a reduced power state when an acknowledgement of the request is received and execute a second process of restoring power to the components when one or more of the components are indicated to be active.

Abstract: A method and apparatus for managing a controller includes indicating, by a processor of a first device, to the controller of a second device to enter a second power state from a first power state. The controller of the second device responds to the processor of the first device with a confirmation. The processor of the first device transmits a signal to the controller of the second device to enter the second power state. Upon receiving a wake event, the controller of the second device exits the second device from the second power state to the first power state.

Abstract: Devices and methods for cache prefetching are provided. A device is provided which comprises a quality of service (QOS) component having first assigned registers used to store data to execute a program, a plurality of non-QOS components having second assigned registers used to store data to execute the program and a power management controller, in communication with the QOS component and the non-QOS components. The power management controller is configured to issue fences for the non-QOS components when it is determined that one or more of the non-QOS components are idle, issue a fence for the QOS component when the fences for the non-QOS components are completed and enter a reduced power state when the fences for the non-QOS components and the fence for the QOS component are completed.

Abstract: Devices and methods for transitioning between power states of a device are provided. A program is executed using data stored in configuration registers assigned to a component of a device. For a first reduced power state, data of a first portion of the configuration registers is saved to the memory using a first set of linear address space. For a second reduced power state, data of a second portion of the configuration registers is saved to the memory using a second set of linear address space and data of a third portion of the configuration registers is saved to the memory using a third set of linear address space.

Abstract: A disclosed technique includes transmitting data in a first buffer associated with a first display pipe to a first display associated with the first display pipe; transmitting data in a second buffer associated with a second display pipe to the first display; requesting wake-up of a memory; and refilling one or both of the first buffer and the second buffer from the memory.
