For certain purposes it can be real nice to have access to a processor that can handle "real-time" processing. No matter how fast CPU's get they still use Operating Systems which interupt tasks whenever they want. Sometimes you *HAVE* to know that a loop is going to take 250us. Now, if CPU's get so cheap that they can throw a couple into a box and the silicon designers provide ways to invalidate pipelines and anything else that can screw up timing. Maybe we will see the DSPosaurs fall into the tar pits. > Bruce Mike ve access to a processor that can handle "real-time" processing.
