An educational software system of a tiny self-compiling C compiler
An educational software system of a tiny self-compiling C compiler, a tiny self-executing RISC-V emulator, and a tiny self-hosting RISC-V hypervisor. Selfie is a project of the Computational Systems Group at the Department of Computer Sciences of the University of Salzburg in Austria. The Selfie Project provides an educational platform for teaching undergraduate and graduate students the design and implementation of programming languages and runtime systems.
Emulator of the ancient 8 bit microprocessor SC/MP 2
...You may slow down the CPU operations, displaying the CPUs status register as LEDs, to watch the CPU working with its registers.
The emulator also contains a VDU (video display unit) output / ASCII input simulation. There are some demos in /etc. And have a look to the NIBL / TINY BASIC interpreter in the TINYBASIC folder, most of the code is over 40 years old.
Have fun,
