Study Notes
Microprocessor Architecture and Microcomputer Systems
- A microprocessor is the central processing unit of a computer system that processes a distinct set of instructions and programs.
- It is made up of tiny components like diodes, transistors, and registers that work together.
- A microprocessor is a programmable device that takes in data, performs arithmetic or logical operations, and produces processed results based on instructions and programs stored in memory.
Microprocessor Components
- Arithmetic and Logic Unit (ALU): performs arithmetic and logical operations like addition, subtraction, AND, OR, XOR, etc.
- Register Array: includes six general-purpose registers, one accumulator, and one flag register in the 8085 microprocessor.
- Control Unit: provides timing and control signals to the microprocessor to perform operations like read and write from memory and peripherals.
Memory
- Stores information in binary format.
- There are two types of memory:
- Read Only Memory (ROM): a nonvolatile memory that stores information that does not change.
- (No mention of a second type of memory, but it can be inferred that there is another type)
Microprocessor Operations
- Takes in data from input devices.
- Performs different operations on data based on instructions given.
- Manipulates data by changing the operation carried out by the instruction.
- Only understands binary data or numbers (bits).
- Identifies and manipulates groups of bits together.
