Summary

I currently creating my own CPU from scratch. At first I am running it in Logisim, a logic simulator but I planed to build a simplier version in hardware subsequently. Here is the overview on the current state of the simulated CPU:

Control Panel

Microcode Processing

State Logic

Loading Logic

Memory-Mapped IO, TIMER0, and INT0

Status

I finished the pre-project: 4Bit Relay Adder to gain some insights into relay logic. I decided to first build a much simpler 4 bit cpu from relays, without any transistor. You find the documentation of this second pre-project here: EuroTwo CPU.

Documentation

As I cannot document it here in detail I will upload my documentation from time to time.

Planned and ideas

Add UART Controller from ATMEGA32
