Abstract :
This paper exemplifies the similarities in Time Warp and computer architecture concepts and terminology, and the continued trend for convergence of ideas in these two areas. Time Warp can provide a means to describe the complex mechanisms being used to allow the instruction execution window to be enlarged. Furthermore it can extend the current mechanisms, which do not scale, in a scalable manner. The issues involved in implementing Time Warp in a CPU design are also examined, and illustrated with reference to the Wisconsin Multiscalar machine and the Waikato WarpEngine. Finally the potential performance gains of such a system are briefly discussed
