Study Notes
Basic Structure of a Computer System
- A computer system consists of three main components: Arithmetic Logic Unit (ALU), Control Unit, and Bus Structure
- The ALU performs arithmetic and logical operations
- The Control Unit retrieves and executes instructions
- The Bus Structure provides a communication pathway between different components
Von Neumann Architecture
- A fundamental design model for computer systems
- Consists of a Control Unit, Arithmetic Logic Unit, Registers, and Memory
- The Control Unit retrieves instructions from Memory, decodes them, and executes them using the ALU and Registers
- The results are then stored back in Memory
Computer Organization and Design
Register Transfer Language
- A language used to describe the operation of a digital computer at the register level
- Used to describe the flow of data and control between registers
Arithmetic and Logical Operations
- Performed by the Arithmetic Logic Unit (ALU)
- Examples include addition, subtraction, multiplication, division, AND, OR, and NOT
Micro-operations
- Basic operations performed by the ALU during execution of an instruction
- Examples include load, store, add, and shift
Shift Micro-operation
- A type of micro-operation that shifts the bits of a binary number
- Examples include left shift, right shift, and circular shift
Computer Registers
- Small amount of memory built into the CPU
- Used to store data temporarily while it is being processed
- Examples include Accumulator, Program Counter, and Instruction Register
Bus System
- A communication pathway between different components of a computer system
- Consists of three types of buses: Address Bus, Data Bus, and Control Bus
- The Address Bus carries memory addresses, the Data Bus carries data, and the Control Bus carries control signals
Instruction Set
- A set of basic instructions that a computer can execute
- Examples include load, store, add, and jump
Timing and Control
- The Control Unit generates timing signals to control the flow of data and instructions
- The timing signals ensure that the correct operations are performed at the correct time
Instruction Cycle
- The process of fetching, decoding, and executing an instruction
- Consists of five stages: fetch, decode, operand fetch, execute, and store
Memory Reference Instructions
- Instructions that access memory locations
- Examples include load, store, and move
Input-Output and Interrupt
- Input-Output (I/O) devices allow the computer to interact with the outside world
- Interrupts are signals that occur when an I/O device needs attention from the CPU
