Abstract: An apparatus and method are disclosed for improving power savings by accelerating suspend and resume operations. The apparatus having a main integrated circuit, the integrated circuit having a context area, a context snooper, and a context cache, the context area configured to store context change information, the context snooper configured to monitor the context change information, and the context cache configured to store at least a portion of the context change information being monitored by the context snooper; and a memory, the memory configured to receive the at least a portion of the context change information from the context cache upon a suspend process signal to the main integrated circuit, to retain contents during the main integrated circuit suspend, and restore the at least a portion of the context change information to the context cache and/or the context area upon a resume process signal to the main integrated circuit.
