| Jun 20, 2017 at 14:45 | comment | added | Raphael | @DavidRicherby I can't claim to remember with any accuracy, either. We should probably shut up and let the experts deal with this. :'D | |
| Jun 20, 2017 at 13:37 | comment | added | David Richerby | @Raphael I'm gonna plead forgetfulness based on the time since I last studied computer architecture! | |
| Jun 20, 2017 at 13:02 | comment | added | Raphael | @DavidRicherby True. I mixed up pipeline and "only some instructions access memory". Sure, we can slow down everything to memory-access speed. IIRC this is not done, though? | |
| Jun 20, 2017 at 8:26 | comment | added | David Richerby | @Raphael A pipeline still makes sense even if each instruction takes the same amount of time to execute, since there are multiple stages to execution. | |
| Jun 19, 2017 at 21:46 | comment | added | Raphael | Weird. Afaik, MIPS counts as RISC and is has a pipeline and everything. Anyway, please include the reference into your question. Take care to use scientific standards for citations! | |

| Jun 19, 2017 at 21:00 | comment | added | Harry Boulton | Those exact words are from my courses text book, but Stanford university: "RISC processors only use simple instructions that can be executed within one clock cycle" cs.stanford.edu/people/eroberts/courses/soco/projects/risc/… | |
| Jun 19, 2017 at 20:52 | comment | added | Raphael | "my understanding is that all instructions in a RISC architecture should execute in roughtly the same" -- why? Can you cite the material that makes you think that? | |
