Abstract
Toggling between accessing an entry in a global history with a stew created from branch predictions implied by the ordering of instructions within a trace of a trace cache when a trace is read out of a trace cache, and accessing an entry in a global history with repeatable variations of a stew when there is more than branch instruction within a trace within the trace cache and at least a second branch instruction is read out.
