Minima Processor is working on the first processor cores that will be customized to use its timing-control technology to push supply voltages into the near-threshold zone.
Texas Instruments has launched a family of ARM-based microcontrollers intended to act as a migration path from its low-energy 16bit MSP430 series, developing its own flash-capable 90nm process to implement them.
Research by the University of Michigan into subthreshold circuit design has led to spinoff company Ambiq Micro creating a family of microcontrollers that it claims provide an ARM Cortex-M4F with power consumption at levels normally associated with an M0+.
Could subthreshold circuitry help extend the reach of power gating? Mike Muller said during his DAC keynote that the technique looks viable.
