• On large maprinted circuit blocks. On personal computers（PC）and small workstations， the CPU is housed in a single chip called a microprocessor.［4］
back
• A CPU has three typical components， that is Arithmetic and Logic Unit（ALU），Control Unit（CU）and Registers. The ALU is made up of devices called gates that receive one or more inputs and， based upon what function they are designed to perform， output a result.［3］ It performs simple arithmetic and logical operations， such as NOT， Left Shift， Right Shift， Add， Subtract， AND， and OR. CU extracts instructions from memory， decodes and executes them， calling on the ALU when necessary. Registers are temporary memory units that store words. The registers are located in the processor， instead of in RAM， so data can be accessed and stored faster.
