Multi-core cluster processing for secure save and restore operations during deep sleep power state

Abstract

A multi-core cluster computing method for securely saving and restoring context data includes storing, by a last core in a primary cluster, last core context data in a first memory. The method also includes storing, by a secondary core in a secondary cluster, secondary core context data in a second memory. The method further includes entering, by the secondary core, a deep sleep power state. The method still further includes entering, by the last core, a system suspend state. The method also includes entering a boot state, by the last core, by restoring the last core context data.
