Introduction To Microprocessor

MICROPROCESSOR - A Quick Overview 

1.  A Microprocessor is a multipurpose, Programmable clock-driven, register based electronic device that read binary instruction from a storage device called memory, accepts binary data as input and processes data according to those instructions and provides results as outputs.
2.  A Microprocessor is a clock driven semiconductor device consisting of electronic circuits manufactured by using either a LSI or VLSI technique. 
3. A typical programmable machine can be represented with three components : MPU,Memory and I/O as shown in Figure.

• These three components work together or interact with each other to perform a given task; thus they comprise a system 
•  The machine (system) represented in above figure can be programmed to turn traffic lights on and off, compute mathematical functions, or keep trace of guidance system. 
•  This system may be simple or sophisticated, depending on its applications.  
• The MPU applications are classified primarily in two categories : reprogrammable systems and embedded systems 
•  In re-programmable systems, such as Microcomputers, the MPU is used for computing and data processing
