A logic circuit is connected to the program bus for receiving instructions and connected to the data bus for executing logic operations in accordance with at least some of the instructions. The logic operations affect bits in at least one of the data memory locations independently of the electronic computation unit without affecting the accumulator. A control circuit sends instructions to the logic circuit on the program bus and to the electronic computation unit. Other devices, systems and methods are also disclosed.Other References
