Embedded Systems

Classic programmed-learning exercises, refreshed for modern Java and presented in the current MrStyner.com portfolio style.

Modern Java noteThis archive has been refreshed for Java 25 LTS. Core language concepts remain useful, while outdated setup instructions and browser-era Java are labeled or replaced. Java 26 is the current feature release; Java 25 is used here as the stable teaching baseline.

Embedded Systems

A computer system that is part of a larger machine and which controls how that machine operates is an embedded system. Usually the processor constantly runs a single control program which is permanently kept in ROM (Read Only Memory).

The overwhelming majority of processor chips are used in embedded systems. Only 0.2% of processor chips are used in the familiar desktop computer!

A typical embedded system is a cell phone. This is obvious, but there are many less obvious embedded systems. Your car contains dozens of processors, even not counting the audio system. For example, each airbag is controlled by its own computer chip.

QUESTION 10:

Your automobile engine is controlled by a computer. Do you think that this computer has:

  • Input devices?
  • Output devices?
  • Main storage?
  • Secondary storage?
