Abstract
An apparatus and method are shown for collecting a branch history value of a program executing in a processor. A current start address register latches a program count value in response to a trace termination condition, such as an indirect branch instruction. A current branch history register is cleared in response to the trace termination condition and shifts in a branch outcome value of the processor in response to a conditional direct branch instruction. A last trace start address latches the content of the current trace start address and a last branch history register latches the content of the current branch history register when a trace termination condition occurs.
