Explain the installation of the microprocessor CPU Microprocessor
Almikrosberr or a microprocessor .. Was made the first microprocessor at the beginning of the seventies Almaekerobrosissour consists of central processing unit Called to the CPU and is an acronym for Central Processing Unit And of the two link - a connecting the processor with Middle and outer - the logical and commonly called Peripheral I / O Ports
Components of the microprocessor CPU
The Program memory is very small and has been designed to save A small part of the program (and is usually part Reading and writing to and from the EEPROM). Are also Store the addresses of some of the information provided in the External memory EEPROM We have also a small capacity RAM RAM Therefore Valmaekerobrosissour need to memory Help and this requires that the two contact Composed of two parts
1- Data Lines
The entrance of data that must be delivered For the processor to process it. And have 8 or 16 or 32 Pin entrance depending on the type Ability of any processor and 8-bit or 16-bit or 32-bit As these data are usually available in memory External assistance.
2- Address Lines
Who shall put the processor address in the form of 8 or 16 Or 32-bit and then reads the information needed by the Through the Data Entry Data Lines.
A way out of the processor sends it addresses The information provided in the middle and outer (memory Assistance, for example). An example of some types of processors Almaekerobrosissour 68 000 is a processor from a company Motorola processor and the famous Z80.
The Almaekerobrosissour can not Operates independently without the presence of some assistance, such as Memory, for example! If we look at the circle containing Wizard Maekerobrosissour we can see that near Assistance of the processor cores such as ROM-EPROM-EEPROM. If the cycle of Almaekerobrosissour is the most complex Of Almacairokntrul
