How to Decode and Execute a Program on a Bus
During the decode and execute phase, we send out signals to try state buffers. We need to ensure that exactly the right combination of these control units are sent because if even one control bit is off, then the wrong register might be loaded on to the bus. So we need to be sure that our decode, our decoding unit in te in the control unit, works perfectly and it always sends out the right sequence of control bits. When given a particular instruction in the instruction register. Were x. And why? Are just arbitrary address locations in the memory. Now in the final phase that i mentioned, remember i talked about three phases in this hypothetical example. Sending control bits into multiplexus so that
