Abstract
Methods and apparatuses for reducing power consumption of processor switch operations are disclosed. One or more embodiments may comprise specifying a subset of registers or state storage elements to be involved in a register or state storage operation, performing the register or state storage operation, and performing a switch operation. The embodiments may minimize the number of registers or state storage elements involved with the standby operation by specifying only the subset of registers or state storage elements, which may involve considerably fewer than the total number of registers or state storage or elements of the processor. The switch operation may be switch from one mode to another, such as a transition to or from a sleep mode, a context switch, or the execution of various types of instructions.
