Nobody has put any real thought into the requirements of DSPs yet.
Embedded and real-time systems have proven to be difficult enough to
pin down. I suspect that DSPs would require a subset of the RT subset
of EL/IX, perhaps with special schedulers and variations of some
communications primitives. Whether we need to provide a specific DSP
subset, or whether this would just be a version of the real-time
subset I don't really know yet.

Suggestions and comments about what would be good for DSPs are very
welcome. This would at least help to ensure that the next version of
EL/IX is not actively DSP-hostile.
