Microprocessor Characteristics

 MICROPROCESSOR THE CHARACTERISTICS OF MICROPROCESSOR 

1. N-bit processor: A processor is n-bit processor implies that

(a) Its ALU is n-bit,i.e. the ALU can perform n-bit operation simultaneously.
(b) Its internal data bus and register size is n-bit
(c) Its external data bus is also n-bit

2. processing capability:It depends upon the number of instructions and flexibility

of each instruction.

3. word length: It depends upon the width of internal data bus, registers , ALU etc.

4. clock frequency: the processing speed of microprocessor depends upon clock frequency.

5. Width of the data bus: this parameter decides word length of the microcomputer.
this is the width of the external data bus.

6. Width of the address bus: This parameter decides the memory addressing capability
of the microprocessor.

7. I/O addressing capability: The maximum number of the I/O ports accessed by the
microprocessor depends upon the width of the I/O address provide in the I/O instruction.

8. Data types: The microprocessor handles various types of data formats like binary,
BCD, ASCII, integers, real numbers signed numbers and unsigned numbers etc.

9. Interrupt capability: Interrupts are used to handle unpredictable and random
events in the microcomputer. It is used to interrupt the microprocessor.
it is also used to speed up the I/o programs.
