Abstract: In one embodiment, a method by an Energy processing Unit (EPU) of a computing system includes detecting an event that triggers an integrity verification on a block of the local memory, determining that a hash for the block of the local memory is available, causing data corresponding to the block of the local memory to be read from a source location in response to the determination, performing an in-line hash operation on the data corresponding to the block of the local memory, and comparing an output of the in-line hash operation and a known hash for the block of the local memory.
