Page 7 - ... processing unit (CPU) is the heart of the computer system. It is responsible for performing all arithmetic operations and logic decisions initiated by the program. In addition to arithmetic and logic functions, the CPU controls overall system operation. On the other hand, the input and output units are the means by which the CPU communicates with the outside world. The input unit is used to input information and commands to the CPU for processing. For instance, a Teletype terminal can be used...
Page 7 - Control Circuitry The control circuitry is the primary functional unit within a CPU. Using clock inputs, the control circuitry maintains the proper sequence of events required for any processing task. After an instruction is fetched and decoded, the control circuitry issues the appropriate signals (to units both internal and external to the CPU) for initiating the proper processing action. Often the control circuitry will be capable of responding to external signals, such as an interrupt request.
