Study Notes
Computer Organization and Architecture
- A computer is a device that accepts information, manipulates it, and produces a result based on a program or sequence of instructions.
- A computer also includes the means for storing data, including the program, for some necessary duration.
Architecture and Organization
- Architecture refers to the attributes visible to the programmer, including instruction set, number of bits used for data representation, I/O mechanisms, and addressing techniques.
- Computer architecture is defined as the internal arrangements of a computer, including the design of the processor, memory, and input/output circuits.
- Organization is the implementation of architectural specifications, including control signals, interfaces, and memory technology.
Structure and Function
- Structure refers to how components relate to each other, including how they are connected and dependent on each other.
- Function refers to the operation of individual components as part of the structure.
Computer Functions
- Data processing
- Data storage
- Data movement
- Control
Functional View
- Operations include:
- Data movement operations
- Storage operations
- Processing from/to storage operations
- Processing from storage to I/O operations
Computer Structure
- The CPU controls the operation of the computer and performs data processing functions.
- Main memory stores data.
- I/O moves data between the computer and its external environment.
- System interconnection provides for communication among CPU, main memory, and I/O.
CPU Structure
