US Patent 7797523 Method and system of executing stack-based memory reference code

A method and system of executing stack-based memory reference code. At least some of the illustrated embodiments are methods comprising waking a computer system from a reduced power operational state in which a memory controller loses at least some configuration information, executing memory reference code that utilizes a stack (wherein the memory reference code configures the main memory controller), and passing control of the computer system to an operating system. The time between executing a first instruction after waking the computer system and passing control to the operating system takes less than 200 milliseconds.
