Abstract: In one example, a processor may include a processor core with a central processing unit as well as a processor cache separate from the processor core. The processor may also include flushing circuitry. The flushing circuitry may identify a power loss event for the processor. In response, the flushing circuitry may selectively power the processor by providing power to the processor cache but not to the processor core. The flushing circuitry may further flush data content of the processor cache to a non-volatile memory separate from the processor.
