Real Time or Real Linux?: A Realistic Alternative

Overview Designers of embedded systems have become increasingly interested in the Linux operating system, largely because of its open source model. But, as it turns out, the standard Linux kernel can't deliver the hard realtime capabilities - such as predictable response times and microsecond latencies - that a large number of embedded systems demand. Meanwhile, others have proposed a "Pure" Linux solution that, to be effective, would require a rewrite of the Linux driver and virtual file system frameworks. This paper looks at an alternate approach - using a POSIX-based RTOS designed specifically for embedded systems - that not only allows Linux developers to keep their programming model, but also maintains the key advantages of Linux's open source model.
