摘要:
Data transfer during processor context switching is reduced, particularly in relation to a time-sharing microtasking programming model. Prior to switching context of a processor having local memory from a first to a second process, a portion of the local memory that does not require transfer to system memory for proper saving of data associated with the first process is determined. The context of the processor is then switched from the first to the second process, including transferring all of the local memory as the data associated with the first process, to system memory—except for the portion of the local memory that has been determined as not requiring saving to the system memory for proper saving of the data associated with the first process. Therefore, switching the context from the first to the second process results in a reduction of data transferred from the local memory to the system memory.
