A microprocessor executes a collection of machine instructions that tell the processor what to do.
An intel microprocessor 8085 chip
- A microprocessor is a programmable logic device that can be used to control processes or to turn on/off devices.
- It is a programmable integrated device that has complexity and decision-making capability similar to that of the Central Processing Unit(CPU) of a computer.
Based on the instructions, a microprocessor does three basic things:
- Using its Arithmetic Logic Unit(ALU), a microprocessor can perform mathematical operations like: addition, subtraction, multiplication and division. Modern microprocessors contain complete floating point processors that can perform extremely sophisticated operations on large floating point numbers.
- A microprocessor can move data from 1 memory location to another.
- A microprocessor can make decisions and jump to a new set of instructions based on those decisions.
