Working on my own 8-bit CPU on my FPGA. So far I can load and store to A, X, and Y registers and a memory address!
That's it so far.
Is it going to be 6502-like, Z80-like? Or, is this 100% "from scratch" you decide which instructions you want and which you don't?
A, X, and Y registers makes me think you're going the 6502-like route.
@profoundlynerdy 6502 like but not tied to the specific architecture. I’m making a toy project and didn’t want to get bogged down in trying to emulate an existing system, especially since it’s an 8 bit system where I wouldn’t need more than an assembler written in Python anyway.
@luigithirty That's really cool.
Is this on GitHub somewhere? You've got a really cool project on your hands.
@profoundlynerdy https://bitbucket.org/LuigiThirty/fpga-calc/src/2ddc6d55aba00642d04eced8df7f4d11e7b99eac?at=master but it’s pretty disorganized and still full of RISC detritus
