Abstract
Power conservation without performance reduction in a power-managed system is disclosed. A method according to one embodiment of the invention includes three steps. In the first step, it is determined whether a computer program running on a computer is substantially memory-intensive or substantially compute-intensive. In a second step, the clock speed of the computer system is increased, and the number of memory access wait states of the computer system is adjusted incident to determining that the computer program is substantially compute-intensive. In a third step, the clock speed of the computer system is decreased, and the number of memory access wait states of the computer system is adjusted incident to determining that the computer program is substantially memory-intensive.
