It wasn’t very long ago that the embedded world scoffed at the idea that an operating system designed for the palatial IT world could find its way in to an embedded system. Memory constraints and ‘real time’ requirements brought to mind the proverb involving a camel and the eye of a needle.
However, where there’s a will there’s normally a way and embedded Linux is now a force to be reckoned with. True, there are still some issues surrounding its real time performance, but equally there are just as many interpretations of what ‘real time’ actually means.
Such is the swing in the balance of power that, today, the open source and open standards communities strongly influence commercial vendors. Licensing models have been put through the corporate wringer to make them more attractive to proponents of ‘open software’, whilst the most radical example in recent history has been the ceremonial unveiling of source code. And it doesn’t stop there; currently, there is an ongoing and noticeable shift towards the adoption of Posix – to a greater or lesser degree.
