摘要:
A method and apparatus for improving the resume time of a platform. In one embodiment of the invention, the context of the platform is saved prior to entering an inactive state of the platform. When the platform is switched back to an active state, it reads the saved context and restores the platform to its original state prior to entering the inactive state. In one embodiment of the invention, the platform determines whether it should compress the saved context before storing it in a non-volatile memory based on the operating condition of the platform. This allows the platform to select the optimum method to allow faster resume time of the platform.
