Not every embedded system needs high-end Pentium-PC compatibility. In fact, of the nearly 2 billion microprocessors fabricated each year, more than 80 percent go into embedded systems with highly specialized functions.

Embedded devices like web phones, programmable logic controllers, and remote digital cameras often utilize “MMU-less” processors to reduce both cost and power consumption. Although these devices are very compact, low power, highly constrained in terms of resources such as memory, and are often diskless, they can still run Linux.

This whitepaper briefly describes some of the technical issues associated with creating small foot-print MMU-less embedded devices under uClinux.
