Examples[edit] Examples of firmware include: In consumer products: Timing and control systems for washing machines Controlling sound and video attributes, as well as the channel list, in modern TVs EPROM chips There are many homebrew projects for video game consoles, which often unlock general-purpose computing functionality in previously limited devices (e.g., running Doom on iPods).

They will also provide the necessary software tools to write the new firmware onto those devices.
