| Jul 3, 2021 at 7:35 | comment | added | Shashank V M | You need RAM to run your program @nvs0000 Of course you can directly issue instructions to the decoder, that would be harder. I would suggest you clarify with your professor what exactly you are expected to build | |
| Jul 3, 2021 at 7:32 | comment | added | nvs0000 | Is there no way to build one without RAM? If so then my struggle correctly defined, the part where I can't get memory address back into RAM...? | |
| Jul 3, 2021 at 7:21 | comment | added | Shashank V M | @nvs0000 You need instruction memory. RAM is used to store the program | |
| Jul 3, 2021 at 7:17 | comment | added | nvs0000 | thanks. I don't know if I'm overkilling for this question or not. It's worth only 5%, which is why I asked for the most efficient way to implement a control unit that performs addition, logic bitwise AND, and right logic shift per requirement. I've struggled with it for weeks now. Every other way I see requires building an entire control unit with RAM. Does a control unit technically need RAM?... | |
| Jul 3, 2021 at 3:39 | comment | added | Shashank V M | @nvs0000 no, it's not so simple. You are asking "does this control unit work with my ALU" - This question hints at a lack of understanding of how CPU design works. You need to do a block diagram first. | |

| Jul 3, 2021 at 1:03 | comment | added | nvs0000 | I tried going specific and even rephrasing, but it seems like it needs more context as well. All i'm trying to nail down here is how to pass the memory address back into RAM: electronics.stackexchange.com/questions/573385/… /// Are you able to help? | |
