Embedded Systems

• What is an embedded system?

  A computer system built into a larger machine
• What is the purpose of an embedded system?

  To provide a means of control
• How do embedded systems perform tasks?

  They execute specific pre-programmed tasks stored in ROM
• What components do embedded systems use?

  A combination of hardware and software
• What are the characteristics of embedded systems regarding storage and processing power?

  They have small storage and low processing power
• Give an example of an embedded system.

  A washing machine
• What does the control chip in a washing machine do?

  It manages the different program cycles
• What is another example of an embedded system?

  A traffic light
• What does the control chip in a traffic light do?

  It determines when to change lights
• What are the key features of embedded systems?

  • Built into larger machines
  • Perform specific tasks
  • Use hardware and software
