A portable computing device synchronously offloads tasks from a first processing resource to an alternative processing resource. Offload requests are centralized and communicated to a dispatch controller. The request defines the alternative processing resource and the location of items in a common or shared memory related to a thread that is desired to be transferred or dispatched from the primary processing resource to the identified alternative processing resource. The dispatch controller, in response to the request, creates a task dispatch packet that provides the information required to switch the context of the thread that was previously executing on the primary processing resource to the alternative processing resource. The common or shared memory space is leveraged to provide desired performance. Results generated by the alternative processing resource are available in the shared memory space upon return to the primary processing resource. |
