    摘要： An energy consumption monitor for use in an electronic system comprising an integrated circuit such as a microcontroller. The monitor comprises a counter adapted to accumulate pulses developed by a charge source, each pulse indicative of the delivery of one unit of charge to a load circuit. A monitoring facility monitors the counter to develop an energy consumption record over time.

    摘要： A method and apparatus for generating an accurate clock generator timing source, comprising minimal jitter, excellent resolution, and an extended calibration range, for use, for example, in a system requiring accurate low power operation. In particular, a clock generation system is adapted to receive a generated clock input, a reference clock input, and an adjustment parameter comprising a sign bit and p data bits. The calibration logic system is further adapted to output and modify a calibrated clock, using distributed pulse modification. The adjustment parameter may be automatically generated.

    摘要： 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.

    摘要： A system for determining a power requirement for a device powered by a buck converter on a system on chip based on Time on pulses (Ton) is disclosed. A buck converter supplies output voltage to enable the device. The buck converter is driven by a Ton pulse generator generating Ton pulses to control charging of a load capacitor. A counter counts the Ton pulses during the supply of output voltage while the device is enabled. A controller is coupled to the counter and the buck converter. The controller determines the power requirement for the device based on the count of the Ton pulses. The power requirement may be used to adjust the trim value to change the width of the Ton pulses for greater energy efficiency.
