Consider the following statements about embedded systems.

1. They are always single-chip designs   2. They frequently have real time deadlines   3. They are usually optimised for cost and power rather than peak performance

  • A.1, 2 and 3 are all correct statements about embedded systems
  • B.1 and 2 only are correct
  • C.1 and 3 only are correct
  • D.2 and 3 only are correct

Answer: D

Deadlines and the cost and power emphasis are both characteristic. Single-chip construction is common but far from universal: an avionics computer or a car's infotainment unit is an embedded system spread over many devices and several boards.
