Patent ID: 7058829

Claim:
A method, comprising: (a) transitioning a computing system from a normal active mode to an active sleep mode, said transitioning comprising: storing active sleep mode software instructions to be executed by a low end central processing unit into an on chip cache that cached normal active mode software instructions that were executed by a high end central processing unit during said normal active mode, said active sleep mode software instructions to be executed by said low end central processing unit during said active sleep mode, said computing system consuming less power during said active sleep mode than during said normal active mode; placing a graphics controller into a low power state in which said graphics controller will not perform graphics processing tasks in said active sleep mode that it performed in said normal active mode; and (b) during said active sleep mode: executing at least a portion of said active sleep mode instructions in order to wirelessly receive information; transferring said information from a wireless interface to said on chip cache; executing at least a second portion of said active sleep mode instructions in order to compress said information before it is stored externally from said cache.
