Study Notes

Computer Architecture

  • Determines which attributes are important for a new computer and designs the system that performs optimally within cost, power, and availability limitations.
  • Responsibilities include instruction set design, functional organization, logic design, and implementation.
  • Leverages relevant tools, standards, and engineering constraints to achieve optimal performance.

Design Goals

  • Shapes a computer system based on constraints and objectives.

Design Variables

  • Standards
  • Cost
  • Memory Space
  • Latency
  • Throughput
  • Features
  • Scale
  • Weight
  • Reliability
  • Expandability
  • Power Consumption

Cost

  • Often kept constant and dictated by device or commercial criteria.

Performance

  • Measured by Clock Speed.
  • Clock Speed: the number of cycles per second that the CPU’s main clock runs at.
  • Expressed in MHz or GHz.
  • A higher clock rate contributes to faster processing speed and better performance.

Computer Technologies

  • Includes system architecture, organization, tools, applications, and technology.

System Architecture

  • Refers to the entire structure and the details needed for functionality.
  • Covers computer systems, microprocessors, circuits, and system programs.
  • Implies how the elements of a computer fit together.

Computer Organization

  • Represents the implementation of the computer architecture.
  • Refers to the computer’s implementation in terms of actual hardware.

Factors Affecting the Computer Designer

  • Architecture
  • System
  • Organization
  • Tools
  • Applications
  • Technology
