The Parallel State Processor

The Parallel State Processor (PSP) is intended as a design concept of the basic engine in large scale multiprocessors. Rather than switching between threads, PSP maintains a basic processor state which is itself a parallel conjunction of fetch and decode along multiple threads as well as the synchronization which occurs when operands are passed between them. This view gives rise to the possibility of an intelligent parallel state, i.e., one which dynamically maximizes the lifetime of the threads it comprises by having them provide one another with the arguments they require over time. We present experimental data verifying that such behavior can be observed in actual code
