Linux Journal: Open Source Software for Real-Time Solutions

“… takes a look at two open-source solutions for embedded
systems: RTLinux and eCOS from Cygnus.”

“… open-source software is also moving into the embedded
real-time marketplace. Last year, Cygnus Solutions unveiled a new
initiative called eCos (embedded Cygnus operating system). eCos is
available as both open source and royalty free. Today, eCos has
been downloaded by well over 10,000 developers. Why didn’t Cygnus
choose Linux as its open-source real-time alternative? This article
will compare and contrast these two alternatives and explain why
each can have a place in your real-time solution.”
