Abstract: Power draw stabilization is provided. A target power consumption of a source load is determined. The source load is generated by electronics supplied power by a primary power source through a power rail. The power rail is coupled to a capacitor bank by a bi-directional converter configured to smooth fluctuations in power drawn from the primary power source by performing mode switch operations. The mode switch operations include, in response to the source load exceeding a target power consumption, controllably switching to a second directional mode that directs current released from the capacitor bank to the power rail. The mode switch operations further include, in response to the source load dropping below the target power consumption, controllably switching the operational mode of the bi-directional converter to a first directional mode to direct current from the power rail into the capacitor bank.

Abstract: Circuitry including cache storage and control circuitry is provided. The cache storage includes an array of random access memory storage elements, and is configured to store data in multiple cache sectors, each cache sector including a number of cache storage data units. The control circuitry is configured to control access to the cache storage including, for example, accessing the cache storage data units in the cache sectors. After accessing a cache storage data unit in a cache sector, the energy requirement and/or latency for the next access to a cache storage data unit in the same sector is lower than the energy requirement and/or latency for the next access to a cache storage data unit in a different same sector.
