Study Notes
Microprocessor Introduction
- Computers have evolved significantly from their early forms like the abacus to modern designs.
- Early computers, like ENIAC, used vacuum tubes.
- Transistors replaced vacuum tubes for better performance.
- Integrated Circuits (ICs) combined transistors on a silicon chip.
- Microprocessors miniaturize the central processing unit (CPU) onto a single chip.
- Microprocessors offer increased speed, lowered cost, and smaller size.
- The first microprocessor was designed by BUSICOM.
- Intel later acquired the rights for the design.
- This paved the way for the development of many different microprocessor models.
Types of Computers and Microprocessors
- Early computers focused on tasks like arithmetic and astronomical calculations.
- Analog computers performed calculations with continuous variables.
- Digital computers perform calculations with discrete digits leading to faster computation.
- Punched cards were used for controlling program lines.
- Pocket calculators and slide rules were also early forms of computation devices.
Key Components of Microprocessors
- CPU: The central processing unit, performing computing operations.
- ALU: Arithmetic Logic Unit, carries out arithmetic operations.
- CU: Control Unit, manages instructions.
- Memory: Holds data and instructions.
- I/O Ports: Communicates with external devices.
- Bus: Provides communication pathways.
Types of Microprocessors
- Intel 4004: The first single-chip microprocessor.
- Intel 8008: 8-bit microprocessor.
- Intel 8080: A significant improvement on the 8008, faster processing.
