What is an embedded system?

A component of a larger system

Special-purpose computer system designed to perform one or a few dedicated functions

There is no single formal definition

How big is the market?

How big are the combined markets of mobile phones, set-top boxes and other consumer electronics.

Why Linux?

Who will win the mobile phone market share? Google Android RIM Blackberry Microsoft Mobile Apple iPhone OS

A consortium comprising the largest manufacturers and software developers Open Handset Alliance Linux Mobile Foundation

What architectures are embedded designers using?

What is iPKG iPKG is the Itsy Package Management System originally designed for smartphones like the Compaq iPAQ “Do it like dpkg unless there is a strong reason not to” Small, fine grain packages which run on limited capacity devices It is now finding its way onto different consumer devices. OpenMoku uses a fork of iPKG, oPKG LinkSys, NSLU2 can use iPKG

“Do it like dpkg unless there is a strong reason not to”

Small, fine grain packages which run on limited capacity devices

It is now finding its way onto different consumer devices.

What is the NSLU2 and why do I have one? The NSLU2 is one of a variety of new embedded pieces of hardware that when combined with Linux can perform very different tasks to that which it was originally designed for. 266MHz Intel Xscale IXP420 CPU. 32MB SDRAM and 8MB flash. 2 USB-2.0 ports and a network port.

What is my UNSLUNG NSLU2 doing? Currently not much, as its here... Normally though it runs: CIFS/SMB server for Windows machines... :( NFS server Media Player through uShare – DLNA + 360 compliant Print Server through CUPS Backup through rsync and cron tasks Mine doesn't but it can: Asterisk – Home VoIP PBX BitTorrent for downloading CaixaMagica ISOs... Web server + many other basic server tasks.

NFS server

Media Player through uShare – DLNA + 360 compliant

Print Server through CUPS

Mine doesn't but it can:

Asterisk – Home VoIP PBX

BitTorrent for downloading CaixaMagica ISOs...

Web server + many other basic server tasks.
