Based on the reprogrammable ICE-Grain Power Architecture, Sonics ICE-G1 Energy Processing Unit (EPU) aggregates both active and static power savings techniques into an automated methodology that users can scale and repeat from their first chip design to its derivatives to extract more savings through successive refinement. EPUs process millions of power state transitions per second (MSPS) in parallel, hundreds of times more than software-based approaches using dedicated microcontrollers, while delivering deterministic responsiveness.


Chip designers waste too many energy-saving opportunities with conventional power management approaches because they can t easily expose them, nor transition circuit states fast enough to take advantage of them. The ICE-G1 Energy Processing Unit (EPU) exploits circuit idle moments those periods of time when circuits are not needed for productive work to make power state transitions up to 500 times faster than conventional approaches while supporting simultaneous switching of an unlimited number of power grains. The new metric for power management is millions of power states per second or MSPS. Like MIPS for measuring the performance of CPUs, MSPS provides a metric of performance for EPUs. ICE-G1 enables processing of many MSPS in every chip.
