    Is "Harvard Architecture" really the best name for this?
    Seems to me it includes only a small subset of the total set of
    architectures that have multiple address spaces for different uses.

It could have multiple address spaces for a variety of reasons -- for
example, the Sony Playstation 2, if I recall correctly, has 5 total
processors in it of 2 (or is it 3?) different types.  Each has its own

Are there issues people wish to discuss beyond the issues that arise
as a result of multiple address spaces?

    I don't know that the d10v was all the good a reference implementation
    or that one is even needed for the task at hand.
