I'm only in software, but it looks like the hw guys don't read the news,
so I'll try my best.

>1) MMU:

No, it's compatible with the NS32382.

a) FIFO. b) None, it's done in parallel with the translation.

>2) Caches:

?? The 32332 has no cache; the bus protocols are the same, but some illegal
accesses may be treated differently.

>      Is there a burst mode to fill the caches?
Yes.

>3) Publications:

There's a little brochure titled 'NS32532-20/NS32532-25/NS32532-30
Highly Integrated 32-Bit Microprocessor' that should be available
at your local NS bureau.

>Thanks for any answers!
You are welcome!
