Linux's minimum requirement of 32 bits is really pushing the limit of "embedded". > Cheap, low end consumer grade > routers these days usually have at least 4 MB of RAM - and I just > checked the homepage of the OpenWrt wiki, and noticed a note referring > to "lower end devices with only 16 MiB RAM". Are you saying that these > are not considered embedded? As long as you can install additional software - it's not "embedded". OpenWrt is the full-blown multipurpose OS. The real "embedded" system consists of OS kernel and one single userspace program. And that's it. True, it's considered easier to patch a Linux kernel and write some PHP-based (end inevitably - full of security holes) "web-application" to manage a router. Which, along with a router can serve as file-server, torrent seed-box and brewing a coffee :) Hence OpenWrt, dd-wrt, and a hundred of their clones. Good examples of embedded system include (but aren't limited, of course) Sun's ILOM, HP's BMC or that thing they put instead of OS into every SIM-card in existence.
