    摘要: An embodiment of the present invention is a technique to dynamically swap processor cores. A first core has a first instruction set. The first core executes a program at a first performance level. The first core stops executing the program when a triggering event occurs. A second core has a second instruction set compatible with the first instruction set and has a second performance level different than the first performance level. The second core is in a power down state when the first core is executing the program. A circuit powers up the second core after the first core stops executing the program such that the second core continues executing the program at the second performance level.

    摘要: A method and system for reducing power consumption of a computer system by allocating memory pages that are associated with lower memory address before those associated with higher memory addresses. Memory elements that do not include any allocated memory pages and that are positioned at a higher address than a threshold address may have its power consumption reduced when the computer system enters a low power consumption state.
