An adaptive voltage converter adapted to compensate for the exponential sensitivities of sub-threshold and near-threshold circuits. The converter can change its power/performance characteristics between different energy modes. The converter may comprise two or more voltage converters/regulators. A multiplexing circuit selects between the outputs of the several converters/regulators depending on the state of a control signal generated by a control facility. The converter is specially adapted to change the output of each converter/regulator based on a number of variables, including, for example, process corner, temperature and input voltage.

Adaptive voltage converter

A low-power system-on-chip includes an originating controller, a fabric, and a power controller. The originating controller is configured to initiate a memory transaction request including a source address. The fabric includes an arbiter configured to receive the memory transaction request and determine a first memory device associated with the memory transaction request. The power controller is configured to selectively change a first memory bank of the first memory device from a first power mode to a second power mode based at least in part on the source address. The fabric is configured to perform a memory operation by (a) receiving stored data from memory storage locations corresponding to the source address when the memory transaction request includes a read request, and (b) sending data included in the memory transaction request to the memory storage locations when the memory transaction request includes a program or a write request.

On-demand activation of memory path during sleep or active modes

Embodiments of the disclosure are directed to a system having a memory module, a voltage generation module, and a plurality of multiplexors. The memory module has a plurality of memory blocks. The voltage generation module supplies two or more voltage rails. The multiplexors are electrically connected to the voltage generation module. Each memory block is electrically connected to one of the multiplexors. Each multiplexor is configured to switch between the two or more voltage rails based on an operational parameter of each memory block. The operational parameter of each memory block may be process control speed, storage status, an operating mode, temperature, or any combination thereof. The operating mode may further be an active mode, a standby mode, and a deep sleep mode.

Memory module with fine-grained voltage adjustment capabilities

A method of determining power data of a system on a chip is disclosed. A plug-in module is provided for installation on the chip. The plug-in module is activated to take a snapshot of the data in power related registers of components on the chip when user provided software is executed on the system on a chip. The collected data is streamed to an external computing device. A spreadsheet of the collected register data may be displayed. A graphic representation of the collected register data may be displayed.

Method for generating power profile in low power processor

A low power voice processing system that includes a plurality of non-audio sensors, at least one microphone system, and a plurality of audio modules, at least some of which can be configured in selected modes. A context determination module is connected to the plurality of audio modules, and further connected to receive input from the plurality of non-audio sensors and the at least one microphone system. The context determination module acts to determine use context for the voice processing system and at least in part selects mode operation of at least some of the plurality of audio modules.

Power efficient context-based audio processing

A power evaluation tool for a system on a chip is disclosed. The tool includes a power profiling plug-in module executed by a processor on the chip to collect a snapshot of register data of components on the chip associated with power consumption by the system during a certain time. The collected register data is streamed to an external computing device. A data parser module receives the streamed collected register data on the external computing device. A spreadsheet generator module creates a spreadsheet of the collected register data. An interface module displays a graphic representation of the collected register data on a display.

System for generating power profile in low power processor

An accelerometer and a linear resonant actuator (LRA) are mechanically coupled, such as by being mounted to the same circuit board. The output of the accelerometer is evaluated in order to select a drive frequency for the LRA. For example, the drive frequency may be varied while measuring the magnitude of acceleration induced by the LRA. The output of the accelerometer may further be used to perform a fitness tracking function, such as counting steps or detecting an activity level.

Low power adaptive linear resonant actuator driver using accelerometer

A microcontroller system includes a processing unit supporting at least one near or sub Vt circuit and a plurality of memory blocks, each memory block connected to a DMA controller and independently power controlled. A power control system uses power gates to power control at least the memory blocks. In some embodiments, a wake-up interrupt controller is connected to the power control system and a voltage regulator system is used to supply voltage to separate power domains, with the voltage regulator systems controlled at least in part by power gates operated by the power control system. A plurality of clocks can be connected to define clock domains associated with separate power domains.
