Linus Torvalds has been insisting for some time that a prominent part of Linux's future lies in embedded systems, a rather unglamorous child of the computer world.
That future appears to be now, as multiple vendors announce products that extend Linux squarely into the suddenly-hot world of embedded systems. Already we're seeing a race to market, pitting companies with existing products against firms with experience in the embedded field which have upcoming Linux products.
As microprocessors have become smaller and cheaper, more and more products have microprocessors embedded in them to make them "smart". Such products as VCRs, digital watches, elevators, automobile engines, thermostats, industrial control equipment, and scientific and medical equipments are driven by these microprocessors and their software. People use the term 'embedded system' to mean any computer system embedded in any of these products. In an embedded system, the actual programming work is done on a system other than the system on which the software will eventually run. The system that you may ship may or may not have a keyboard, a screen, a diskdrive and other peripherals necessary for programming. Therefore most programming work for embedded system is done on a host, a computer system on which all programming tools run. Only after the program has been written, compiled, assembled and linked, it is moved to the target, the system that is shipped to customers.
