An instruction register operates to hold a branch instruction conditional on a particular set of the status conditions. A decoder is connected to the instruction register and the circuit. A program counter is coupled to the decoder wherein the decoder is operable to enter a branch address into the program counter in response to the branch instruction when the particular set of the status conditions of the circuit are present. Other data processing devices, systems and methods are also disclosed. | |
