Zusammenfassung:An instruction pipeline includes a circuit that can generate a hardware event to indicate conditional branches, including the direction of taken branches. The circuit can generate a forward conditional branch indicator for an opcode when a conditional branch is taken to a forward location from the opcode. The instruction pipeline includes a counter to increment in response to the forward conditional branch indicator, which will indicate a frequency of forward conditional branches for the opcode.
