Abstract
A method is described that involves storing active sleep mode software instructions to be executed by a low end central processing unit into an on chip cache that caches normal active mode software instructions executed by a high end central processing unit. The active sleep mode software instructions are to be executed by the low end central processing unit during an active sleep mode. The normal active mode software instructions are executed by the high end central processing unit during a normal active mode. The active sleep mode consumes less power than the normal active mode.
