#149303 - Memory mapped? Responding to: ???'s previous message |
Stefan Kanev said:
From 80386(or 80286?) IOports can be memory mapped With suitable hardware, ports can be memory-mapped on any processor; it's nothing specifically to do with the processor - the processor remains completely oblivious to whether a particular address decodes externally to "real" memory, or IO. But did the 286/386/whatever have some other special tricks in this area? |

| x86 has a separate IO space from memory space... | 01/01/70 00:00 | |
| Misunderstanding? | 01/01/70 00:00 | |
| 10bits | 01/01/70 00:00 | |
| 16 bits | 01/01/70 00:00 | |
| and more... | 01/01/70 00:00 | |
| Memory mapped? | 01/01/70 00:00 | |
| yes | 01/01/70 00:00 | |
| cache... | 01/01/70 00:00 | |
| IP Ports | 01/01/70 00:00 | |
| Yes thats what I was looking for... | 01/01/70 00:00 | |
Nothing specifically to do with PCs, then! | 01/01/70 00:00 |
