Study Notes
Differences between Computer Architecture and Organization
- Computer Architecture focuses on the high-level design and structure of hardware components and their interconnections, influencing system functionality.
- Computer Organization is concerned with the physical arrangement and operational aspects of a computer system as perceived by the user, acting as the hardware-software interface.
- Architectural elements include instruction sets, addressing modes, and data types, while organizational elements encompass circuit designs and peripherals.
- Architecture considerations precede organization when designing a computer system.
Structure and Function of Computers
- A hierarchical system consists of interrelated subsystems structured until reaching basic elemental subsystems.
- Structure denotes how components interrelate, whereas Function describes the operations of these components.
- Core computer functions include:
- Data Processing: Ability to handle various data forms through different processing ranges.
- Data Storage: Temporary or permanent data storage capabilities.
- Data Movement: Transfer of data between the computer and external entities.
- Control: Regulation of the aforementioned functions.
Main Structural Components of a Computer
- Central Processing Unit (CPU): The core element controlling operations and processing data.
- Main Memory: Responsible for data storage.
- Input/Output (I/O): Facilitates data movement between the computer and the outside environment.
- System Interconnections: Allows communication among the CPU, memory, and I/O devices.
CPU Structural Components
- Control Unit: Oversees and coordinates CPU operation.
- Arithmetic Logic Unit (ALU): Executes data processing tasks.
- Registers: Provide internal storage within the CPU.
- CPU Interconnections: Mechanisms for communication among control units, ALUs, and registers.
General System Architecture
- Memory Unit: Consists of storage cells and associated circuits for information transfer, storing data in word groups.
-
Buses: Enable information sharing among registers:
- Address Bus: Carries addresses (not data) between the processor and memory.
- Data Bus: Transports data between the processor, memory, and I/O devices.
- Control Bus: Transfers command signals from the CPU.
General Purpose Systems
- Represents a modern version of the Von-Neumann Architecture, integrating CPU, memory, and I/O subsystems interconnected via a system bus.
Parallel Processing
- A technique allowing simultaneous execution of data-processing tasks to boost computational speed.
- Enhances throughput by distributing data among multiple functional units.
- Example functional units include:
- Adders and integer multipliers for arithmetic operations.
- Floating-point operations managed by dedicated circuits.
- Concurrent execution of logic, shift, and increment operations.
Flynn's Classification of Computers
- Designed by M.J. Flynn, classifies computer systems based on simultaneous manipulation of instructions and data.
- The instruction stream involves the flow of instructions from memory, while the data stream involves operations performed on data.
- Categories include:
- Single Instruction Stream, Single Data Stream (SISD): A single computer system executing instructions sequentially; may possess internal parallel processing capabilities.
