I have a general interest in old 80’s-90’s era computers. Redstone is a great learning-tool when it comes to understanding the actual hardware.
I modified a harvard style cpu (from a tutorial series by n00basaurus) to von neumann architecture using a state machine as control unit. Basically i took the Alu, dual and single read registers, some decoders and a programcounter module and put them together. All instructions have to be fetched from RAM and executed one at a time. This far i’ve programmed the Collatz problem and the fibonacci sequence.
It has access to 256 bytes of ram, instructions can be 8 bits long but do not have a limit in execution steps (sorry im not good at explaining this). Basically one instruction can have endless steps.
Im planning to build an 8 bit ALU.
I agree with the rules.
