Abstract
A pipelined data processor has instructions at different stages of execution. Some of the instructions specify virtual addresses into a file of registers having physical addresses. A speculative translator maps the virtual registers of an instruction at one pipeline stage into physical registers for speculative use by the instruction at a later pipeline stage. The registers have multiple differently translated regions. Failure of speculative renaming reverts to an archive copy of renaming data.
