Calcutron-33: A Decimal Based RISC Microprocessor

This podcast is will be an early experiment to see how much interest there is in this medium. I am going though the motivations for writing an assembler, disassembler and CPU simulator for a made-up microprocessor called Calcutron-33. It is an unusual CPU architecture as it is decimal based rather than based on binary numbers.

Illustrating an instruction being fetched from memory to be decoded and executed by a RISC-like microprocessors such as Calcutron-33

That choice may seem bizarre, but was made to create an architecture which is easy to understand for beginners to assembly programming. The goal is to create a stepping stone towards to real microprocessor architectures such as RISC-V.

In this podcast I am talking off-the-cuff about the design choices and made and the motivations behind them. If you like this kind of content, please let me know and I will put more effort into recording more episodes.

Suggestions for topics are welcome,
