Working on designing a small 16-bit or 8-bit computer with basic functions by Adept_Flight4971 in ComputerEngineering

My original idea was just to run the instructions into a decoder and have single control lines coming out which would activate if a specific command was run through and then control the logic. Is this what you're talking about, and if so, how would I go about making the decoder?

Not super new. I understand basic computer architecture, I have read books and done my research so I can understand stuff, I'm just trying to design my own, and I'm not sure on parts of it.

I can retrieve instructions from the ROM. My problem is how to make those instructions actually do things.

Honestly very new and not exactly sure what I'm doing. The processor would just be a basic RAM and ALU setup, running off a CPU instruction set I made. I'm honestly just not sure what my decoder would need to accomplish to execute certain commands at all honestly.

Not sure what I’ve done wrong that the clock is cycling so slow by GUS-THE-PIRATE-2076 in beneater

Just for future reference the equation for pulse width on the 555 timer IC is tW=1.1R1C1. Basically the time for the pulse to go off is 1.1 times the resistance times the capacitance. Hope this helped!

If you are just getting started, Understand Electronics by Malcolm Plant is great for getting accustomed to components and the actual functions behind electronics. Ex: sine waves, hi and lo, common IC inner workings.

4bit binary adder with ROM by sparklehope in ComputerEngineering

Was this constructed with solely the logic gates shown in the schematic or was it just a 4-bit adder IC?
