Method and system for application managed context switching |
摘要 |
A method for application managed CPU context switching. The method includes determining whether state data of a CPU is valid for a process. The determining is performed by the process itself. If the state data of the CPU is not valid for the process, the process accesses functional hardware of the CPU to load new state data into the CPU. The process then continues to execute on the CPU using the new state data. If a context switch occurs, the existing state data of the CPU is invalidated. The state data of the CPU can be invalidated by an operating system without storing the state data in main memory.
