Not from what I've understood; it seems as if they have multiple functional
units on their chip.  Nice idea, of course:  Seymour Cray had it in the CDC
Cybers, decades ago (ob. Seymour plug 8-)), and so do MIPS chips, I believe
(although I'm not sure how many the MIPS chips have).

And, of course, the 8088 and 8087 could operate in parallel.  Frightening,
eh?
