摘要: Described is a branch unit that predicts instruction target addresses. The prediction improved by using Call-Return Stack to predict subroutine routine branches. mechanism designed for high-performance processors where call and return instructions may overlap in execution or be issued speculatively. maintains the state known trace tracks speculative traces.
