Huh, what did the Amiga's memory model look like? Could you construct a pointer to 2 GB different locations? Did it have segments like the 8086 or something?
- kstrauser 3y agoIt had a 32-bit address bus, so that was a nice, flat 2GB of directly addressable locations. Edit: You might've been asking a different question. Toward the end, lots of Amigas had MMUs, either as a separate chip or built in to the CPU. VMM and similar programs used the MMU to implement paging.
- schoen 3y agoThose are both interesting answers, and I didn't really know anything about the Amiga's architecture (other than to have imagined wrongly that it might have had 16-bit addresses). Thanks.
