ABSTRACT:
A state machine computing system provides multiple state registers, a recursive hardware state machine computing system; particularly address translation hardware which can be used in multiprocessors, parallel machines and massively parallel machines. The hardware state machine includes a mechanism to push values into a state register stack and to pop values from the state register stack. The stack consists of a plurality of state registers, one of which is designated the current state register and the remainder designated as prior (or saved) state registers. Recursive logic is provided to increment the current state register. The recursive state machine described provides significant advantages over prior art hardware implementations of guest virtual address translation because guest virtual address translations recursively invoke host virtual address translation.
