Why use Tata's Ro-SES OS?

Today we announced that Tata Elxsi's RoS-ES (Real Time Operating System for Embedded Systems) OS is now available for Xtensa and Diamond Standard processors. So why use a small OS like this rather than Linux? When you're using deeply embedded controllers in the dataplane, you don't need all the overhead of most OSes. Tata Elxsi's RoS-ES is a compact real-time operating system (RTOS) that provides an impressive array of capabilities making it well suited to networking and consumer electronics applications. More information on the RoS-ES RTOS is available at www.tataelxsi.com/roses.
