    Abstract: Provided are apparatus and methods for testing an integrated circuit. In an exemplary method for testing an integrated circuit, a test controller and a power manager are integrated into a main power domain of the integrated circuit. The test controller can be Joint Test Action Group-compatible. An isolation signal is generated using the power manager. The isolation signal can comprise at least one of a freeze signal configured to isolate an input-output port of the integrated circuit, and a clamp signal configured to isolate a functional module of the integrated circuit. The isolation signal can be stored in a boundary scan register controlled with the test controller. The main power domain is isolated from a power-collapsible domain of the integrated circuit with the isolation signal. Power of the power-collapsible domain is collapsed. When power is collapsed, the power-collapsible domain is tested using the test controller and the power manager. The testing of the power-collapsible domain can comprise testing a power supply current. When power to the power-collapsible domain is collapsed, a level shifter output can be held constant to an output level based on a pre-collapse input from the power-collapsible domain.

    Abstract: Techniques are provided that may be implemented in a mobile device to provide one or more location parameters to one or more mobile processes (e.g., applications) provided and/or otherwise supported, at least in part, by the mobile device. For example, a mobile device may be configured to monitor one or more processes hosted on a first processor, and initiate a communication on a bus connecting the first processor to a positioning engine external to the first processor to obtain at least one updated location parameter in response to detection of activity of at least one of the one or more processes. In certain instances, the updated location parameter(s) may have been previously determined by the positioning engine.
