Processing

Central processing unit or CPU (central processing unit) contributes to process referrals, perform calculation and deal with excessive menerusi information computer system. Processing units or devices will also communicate with the device input, output and storan to implement directives related.

In the von Neumann architecture of the original, he describes an Arithmetic and Logic Unit and a Control Unit. In modern computers, the two units are located in a single integrated circuit (IC - Integrated Circuit), which is usually called the CPU (Central Processing Unit).

Arithmetic and Logic Unit, or Arithmetic Logic Unit (ALU), is a device that performs the basic implementation as the implementation of arithmetic (addition, subtraction, and the like), the implementation of logical (AND, OR, NOT), and the implementation of comparison (eg, compare the contents of two slots for equality). In this unit performed "work" is real.

Save the command control unit is now done by computers, orders for the implementation of the ALU and get back information (from memory) needed to execute the command, and move back the results to the appropriate memory location. Once that happens, the control unit to go to the next command (usually located in the next slot, except if the order is a jump command that tells the computer that the next order placed at other locations
