Abstract: Adaptive power regulation methods and systems are disclosed. In one aspect, one or more process sensors for memory elements are provided, which report information relating to inherent speed characteristics of sub-elements within the memory elements. Based on this reported information, a controller ascertains an appropriate power level to insure a proper data retention voltage (DRV) is applied on voltage rails by a power management unit (PMU) circuit. By using the proper DRV based on the speed characteristics of the sub-elements within the memory elements, power conservation is achieved.

Abstract: Aspects of the disclosure are directed to a digital design with bundled data asynchronous logic and body-biasing tuning. In one aspect, implementation includes establishing a control path between a first controller and a second controller using a handshaking protocol; establishing a data path between a first latch and a second latch using a bundled data technique; executing a first dynamic body biasing tuning by applying a first body bias signal to the control path; executing a second dynamic body biasing tuning by applying a second body bias signal to the data path. The digital design includes a first controller with a control path to connect to a second controller, wherein a first body bias tuning signal tunes body bias in the control path, a first latch with a data path to connect to a second latch, wherein a second body bias tuning signal tunes body bias in the data path.

Abstract: Clock distribution schemes with wide operating voltage ranges are disclosed. In one aspect, an operating voltage level or condition within a computing device is sensed. In a first voltage condition, delay elements are used within a clock tree to minimize clock skew. In a second voltage condition, one or more delay and/or clocked elements are bypassed to minimize clock skew at the second voltage condition. In addition to controlling clock skew, power may be conserved by depowering the bypassed elements. Controlling clock skew in this fashion improves operation of a computing device that includes the clock tree and may improve battery life.

Abstract: Certain aspects of the present disclosure are directed to methods and apparatus for configuring a multiply-accumulate (MAC) block in an artificial neural network. A method generally includes receiving, at a neural processing unit comprising one or more logic elements, at least one input associated with a use-case of the neural processing unit; obtaining a set of weights associated with the at least one input; selecting a precision for the set of weights; modifying the set of weights based on the selected precision; and generating an output based, at least in part, on the at least one input, the modified set of weights, and an activation function.

Abstract: A system on chip (SOC) includes a power distribution network (PDN) that has two different types of power multiplexers. The first power multiplexer type includes a lower resistance switching logic, and the second type includes a higher resistance switching logic as well as digital logic to provide an enable signal to the first type of power multiplexer. A given first-type power multiplexer may have multiple power multiplexers of the second type in a loop, the loop including communication paths for the enable signal and feeding the enable signal back to an enable input of the first-type power multiplexer.

Abstract: Methods and apparatus for identifying a process corner are provided. Provided is an exemplary method for identifying a process corner of an integrated circuit (IC). The IC has a first asymmetrical ring oscillator (ARO1) including pull-up transistors that have a low threshold voltage (LVT) and pull-down transistors that have a regular threshold voltage (RVT), and has a second asymmetrical ring oscillator (ARO2) including pull-up transistors that have an RVT and pull-down transistors having an LVT. The exemplary method includes applying an ultra-low power supply voltage to the ARO1 and the ARO2 that causes the integrated circuit to operate near a verge of malfunction, measuring an output frequency of the ARO1, measuring an output frequency of the ARO2, calculating a calculated ratio of the output frequency of the ARO1 and the output frequency of the ARO2, and comparing the calculated ratio to a fiduciary ratio to identify the process corner.

Abstract: Electronic devices employing adiabatic logic circuits with wireless charging are disclosed. In one aspect, an electronic device is provided. The electronic device includes a power circuit employing an alternating current (AC) coupler circuit configured to receive a wireless AC signal and generate a wired AC signal based on the wireless AC signal. The power circuit includes a power output configured to provide an AC power signal based on the wired AC signal generated by the AC coupler circuit. The AC power signal is generated based on the wireless charging capability of the AC coupler circuit. The electronic device employs a digital logic system that includes a power rail electrically coupled to an adiabatic logic circuit. The AC power signal is provided to the power rail to provide power to the adiabatic logic circuit. Wirelessly charging the adiabatic logic circuit consumes less power than conventional non-wireless charging circuitry.
