Micro operations are the basic building blocks of instructions that a computer executes. They represent the smallest unit of processing that a processor can perform.
These instructions are responsible for performing various tasks such as:
Reading data from memory
Writing data to memory
Performing arithmetic and logical operations
Comparing two values
They are typically very fast and are executed in parallel with other instructions, contributing to the overall performance of a computer.
Examples:
Loading an integer value from memory into a register
Performing an addition of two numbers
Checking the parity of a bit in a memory location
Micro operations can be further divided into two categories:
Arithmetic and Logical Instructions: These instructions perform calculations on numerical data, such as addition, subtraction, multiplication, and division.
Logical Instructions: These instructions perform comparisons between two data values, such as AND, OR, and NOT.
Understanding micro operations is crucial for understanding how a computer actually works at a fundamental level. They are the building blocks of more complex instructions and are essential for learning how to program computers
