PROBLEM TO BE SOLVED: To provide an embedded processor architecture comprising a plurality of virtual processing units that each execute processes or threads (collectively, "threads"). SOLUTION: One or more execution units, which are shared by the processing units, execute instructions from the threads. An event delivery mechanism delivers events such as, by way of non-limiting example, hardware interrupts, software-initiated signaling events ("software events") and memory events to respective threads without execution of the instructions. Each event can, per aspects of the invention, be processed by the respective threads without execution of the instructions outside that thread. The threads need not be constrained to execute on the same respective processing units during the lives of those threads, though in some embodiments, they can be so constrained.
