How CPU Work

When data and / or instruction to include processing-devices, placed first in the RAM (via Input-storage); ditampung instruction when shaped by the Control Unit in the program-storage, but if the form data in ditampung Working-storage). If the register is ready to receive the fulfillment execution, then the Control Unit will be taking instructions from the program-storage for ditampungkan Instruction to register, while the memory addresses containing the instructions is ditampung in the Program Counter. While the data taken by the Control Unit of Working-storage for ditampung in General-purpose register (in this case in the Operand-register). If based instruction which is performed arithmatika and logic, the pestle will take over operations for the instruction based on the set. Ditampung result in the Accumulator. When the results of the processing is completed, the Control Unit will take the results of the Accumulator to ditampung return to Working-storage. If the entire operation has been completed, the Control Unit will pick up the results of processing for the Working-storage ditampung to Output-storage. And the output from the next-storage, processing results will be displayed to the output devices.
