Abstract
Methods and apparatus for energy management in data storage devices are provided. One such data storage device (DSD) includes a non-volatile memory (NVM), a set of hardware processing engines, and a power sensor to detect a total power consumption of the set of hardware processing engines. A processor is configured to determine an energy-per-processing event value for each of the set of processing engines based on total power consumption measurements and processing event duration values, then control energy delivery to the processing engines based on the energy-per-processing event values in accordance with an energy budget. In some examples, the DSD employs a least-squares procedure to estimate power-per-processing event values so the values can be determined without needing to measure individual power consumption of the processing engines. The power-per-processing event values are converted to energy-per-processing event values based on corresponding processing event durations. A recursive least-squares update procedure is also described.
