Abstract: A locking/unlocking mechanism for a contactless gesture detection system of a device is described herein. The locking/unlocking mechanism can facilitate automatic locking, manual locking, and/or manual unlocking of the contactless gesture detection system. The contactless gesture detection system can implement the locking/unlocking mechanisms described herein to control a contactless gesture-based user interface state of the device. In various implementations, the controlling can include detecting gestures associated with a user in a contactless space associated with the device; detecting a defined gesture sequence over a defined time period from the detected gestures; and transitioning the device to a contactless gesture-based user interface locked state or a contactless gesture-based user interface unlocked state based on the defined gesture sequence.

Abstract: In one particular example, this disclosure provides an efficient mechanism to determine the degree of parallelization possible for a loop in the presence of possible memory aliases that cannot be resolved at compile-time. Hardware instructions are provided that test memory addresses at run-time and set a mode or register that enables a single instance of a loop to run the maximum number of SIMD (Single Instruction, Multiple Data) lanes to run in parallel that obey the semantics of the original scalar loop. Other hardware features that extend applicability or performance of such instructions are enumerated.

Abstract: Apparatus and methods for current sensing in switching regulators are provided. In certain implementations, a switching regulator includes a switch transistor, a replica transistor, a sense resistor, and a current sensing circuit. The drain and gate of the switch transistor can be electrically connected to the drain and gate of the replica transistor, respectively. The current sensing circuit can generate an output current that varies in response to a sense current from a source of the replica transistor. Additionally, the current sensing circuit can sink the sense current when the sense current flows from the drain to the source of the replica transistor and source the sense current when the sense current flows from the source to the drain of the replica transistor. The sense resistor can receive the output current such that the voltage across the sense resistor changes in relation to the current through the switch transistor.
