Systems and methods manage power in an integrated circuit using power islands. The integrated circuit includes a plurality of power islands wherein a power consumption of each power island within the plurality of power islands is independently controlled within each power island of the plurality of power islands. A power manager determines a target power level for one power island of the plurality of power islands. The power manager then determines an action to change a consumption power level of the one power island of the plurality of power islands to the target power level. The power manager performs the action to change the consumption power level of the one power island of the plurality of power islands to the target power level.

Power managers for an integrated circuit

Systems and methods manage power in an integrated circuit using power islands. The integrated circuit includes a plurality of power islands wherein a power consumption of each power island within the plurality of power islands is independently controlled within said each power island. A power manager determines a target power level for one power island of the plurality of power islands. The power manager then determines an action to change a consumption power level of said one power island of the plurality of power islands to the target power level. The power manager performs the action to change the consumption power level of said one power island of the plurality of power islands to the target power level.

An integrated circuit includes first circuitry and sleep transistor circuitry. The first circuitry receives input signals and processes the input signals. The first circuitry also retains data in a sleep state that has low leakage. The sleep transistor circuitry is coupled to the first circuitry and receives a sleep signal that has a negative voltage. The sleep circuitry reduces power consumption of the first circuitry in the sleep state to have low leakage based on the sleep signal while retaining the data in the first circuitry.

Low leakage and data retention circuitry

Systems and methods for managing power in an integrated circuit using power islands are disclosed. The integrated circuit includes a plurality of power islands where power consumption is independently controlled within each of the power islands. A power manager determines a target power level for one of the power islands. The power manager then determines an action to change a consumption power level of the one of the power islands to the target power level. The power manager performs the action to change the consumption power level of the one of the power islands to the target power level.

An apparatus includes circuits, a field line configured to generate a magnetic field based on an input, a sensing module configured to determine a parameter of each circuit, and a magnetic field direction determination module configured to determine an angular orientation of the apparatus relative to an external magnetic field based on the parameter. Each circuit includes multiple magnetic tunnel junctions. Each magnetic tunnel junction includes a storage layer having a storage magnetization direction and a sense layer having a sense magnetization direction configured based on the magnetic field. Each magnetic tunnel junction is configured such that the sense magnetization direction and a resistance of the magnetic tunnel junction vary based on the external magnetic field. The parameter varies based on the resistances of the multiple magnetic tunnel junctions. The magnetic field direction determination module is implemented in at least one of a memory or a processing device.

Magnetic logic units configured to measure magnetic field direction

A system for an integrated circuit comprising a plurality of power islands includes a first power manager and a second power manager. The first power manager manages a first power consumption for the integrated circuit based on needs and operation of the integrated circuit. The second power manager communicates with the first power manager and manages a second power consumption for one of the power islands.
