Abstract
Systems and methods for efficiently switching context between processing elements are disclosed. These systems and methods may transfer the context of a processing element to a storage location. Using the DMA controller of a target processing element, the contents of this storage location may be transferred to another storage location associated with the target processing element. The context may then be restored from this storage location to the proper locations in the target processing element, and the target processing element may then begin processing utilizing this transferred context.
