Study Notes
Microprocessor Systems
- The Arithmetic Logic Unit (ALU) performs arithmetic and logical operations.
Architecture of a Microcomputer System
- The hardware of a microprocessor system can be divided into four functional sections:
- Input unit
- Microprocessing unit
- Memory unit
- Output unit
Number Conversion
- The decimal number 4138 can be converted to hexadecimal form as follows:
- 4138 ÷ 16 = 258, remainder = A (LSB)
- 258 ÷ 16 = 16, remainder = 2
- 16 ÷ 16 = 1, remainder = 0
- 1 ÷ 16 = 0, remainder = 1 (MSB)
- The result is: 102A16
Hexadecimal and Binary Numbers
- Hexadecimal numbers are used in microcomputer-based systems because they can be used to rewrite information in a compact way.
- Hexadecimal numbers can be used to represent data or instructions in a compact form.
