I wanted to share a preview of the senior project that I've been working on this year.
I've hit a major milestone which is rev 1 of my Hack Computer System VHDL design debugged and running on my development board. I have not completed the tool chain stack yet, so I have only run very basic programs that can be hand copied into the binary memory initialization format I use to load my FPGA.
I hope you enjoy my video of Hack running fill.asm from Chapter 4 of the Elements of Computing Systems!
I started N2T in 2014 and completed up to chapter 6.
To do the rest of the chapters, I had to learn to programme.
Taught myself python and VBA and ended up developing a fully functional chess engine in MS Excel.
I had earlier used an excel sheet as an assembler for chapter 4 as I didn't know then to programme in python.
Now I am done with my hobby engine development and back to N2T.
Hope to complete this soon and do a physical implementation in FPGA as you did.
