A computer! Our features:
- A compact and uniform 16-bit instruction format
- A pleasant RISC load-store design, we think, we're not really sure as while we are educated, we are still so ignorant.
- Word-size agnostic. Want a 4-bit CPU? Go for it! 64 bit? Sure!
- A suite of poorly-tested implementations that occasionally make their way onto an FPGA
- A generalized bitwise instruction that can perform any of the 16 2-input boolean functions
Planned features:
- Memory protection scheme
- Interrupts and I/O interfaces
Here you'll find...
doc, with a specification of the instruction set as well as a description of the calling convention.myhdl, an implementation in MyHDL (surprise!) of a core.spinal_ass, an implmentation in SpinalHDL of a core.src, an outdated partial implementation in Chisel of a core.assrs, an emulator in Rust that also has some utilities such as a disassembler and instruction encoderassembler, an assembler in MoonScript that supports labels and a few handy instruction aliases like "LI" to load immediate.
