A context switch request is made from a host unit to a processing engine separately from the method stream to that processing engine and does not require the host unit to know what context the processing engine is currently working on. Upon receiving the request, the processing engine compares the requested context with the context that it is currently working on, and if the two are different, performs the context switch to the requested context. On the other hand, if the two are the same, the engine does not perform the context switch and continues working on the current context.
