Linux is one of the few, ever expanding endeavors developed in the 20th century. Obvious or not, it has continuously cranked itself up to reach new horizons since its humble beginnings in 1991. A more than 50 year old market segment, the embedded systems, which encompasses a vast domain of electronic products ranging from little wristwatch cameras, to huge distributed systems like telecom switches, has been charmed by the frills and thrills of Linux and has deeply benefitted from the same. Embedded Systems are everywhere, ranging from small control applications which require small microcontrollers to massive parallel processors which have colossal memory requirements. Mobile phones, Inverters, microwaves, PDAs, you name it, and you might find an embedded system at its essential core.
