FaVOR ISA

Experimental ISA created for an academic project.
README.md

The FaVOR ISA is an experimental ISA I created for my CS 692 "Advanced Computer Architecture" term project.

For the project, I partially implemented the ISA in GNU binutils, including an emulator for it. I also partially implemented (a version of) the ISA in Verilog for an FPGA.

The core features that the ISA wanted to explore include:

  • Support for fixed-point operations.
  • A focus on vector values that can also be operated on as individual components (common in game development).
  • ISA-level consideration of pointer tagging, including explicitly dropping support for unaligned value access. This feature is also based on my experience with C programming and using pointer tagging.
  • A clean ABI, fixing many of the gripes I have with existing ABIs.

See also the report on the ISA that I prepared for my class.
