Abstract
A method and system are disclosed for saving soft state information, which is non-critical for executing a process in a processor, upon a receipt of a process interrupt by the processor. The soft state is transmitted to a memory associated with the processor via a memory interface. Preferably, the soft state is transmitted within the processor to the memory interface via a scan-chain pathway within the processor, which allows functional data pathways to remain unobstructed by the storage of the soft state. Thereafter, the stored soft state can be restored from memory when the process is again executed.
