I am having a hard time deciding on the correct term to use in describing
certain computing structures.  Rather than invent new terminology, or add to
the confusion by misusing terms, I am soliciting any STANDARD definitions
that exist for the following terms (and any closely related terms):

1) Coprocessor
2) Attached Processor
3) Function Unit
4) Processing Element

By STANDARD definition, I mean a definition used consistently by
(roughly in order of preference):

a) A standards organization (eg. ISO, IEEE)
b) A major computer company
c) A "standard" textbook (eg. Siewiorek, Bell, Newell)
d) A prominent person in the field

You get the idea: I'm not soliciting hordes of pet personal opinions
(unless the person is in category d above!).

I have not found satisfactory definitions yet in the textbooks that I
know of and dont know where else look.
