Future Computer Designs Need Not Be Von Neumann Architecture

With the availability of multicore processors computer architectures need not be Von Neumann architectures anymore. This architecture makes strict serial execution of instructions. Whereas with so many cores available one can issue more than one instruction as long as the input of one does not depend on output of another.

That is much like the multiple execution unit computer we all read about. Vishkin proposes an architecture based on a central coordinating core with multiple execution cores. When execution has to serial, the coordinator can take care of it. Multiple cores take care of independent parallel instruction issues. He proposes this in an article in Communications ACM, Jan 2011.
