In search of resources to learn about MMUs
(1/1)

Hello, forum :)
On my journey into learning digital electronics, i decided to learn about MMUs(and possibly design a simple one, as simple as they can be, just for fun).
I am currently looking for any information about MMUs - programming guides, datasheets, tutorials, forum posts, etc. So if you know anything that can help me, please link these resources, i will very much appreciate it :)

Maybe this will help:

The thing about virtual memory is that it is both hardware and software.
Try to find PDP11/70 manuals in BitSavers - they might help. Maybe even IBM 360,370 or Amdahl 470 manuals (I didn't look).
This topic is covered well in books related to computer hardware design. I don't have any to recommend at the moment.

If you can easily find a book on MIPS (eg, "See MIPS Run"), that might be of interest. When I was doing embedded MIPS, I had to be somewhat familiar with the page fault handler and the mapping descriptors.

A book about the 80386 processor is also helpful. It is interesting to see so much 'old' technology being suggested; I like it because the underlying principles never changed but more complication got added.
