The gol-16 is a 16-bit processor inspired by the 32-bit ARM processor. It includes a custom assembly language with full arithmetic operations, logical operations and conditional branching.
This project features a fully custom assembler written in C, which outputs binary files that can be directly uploaded to
the Logisim Evolution schematic. The assembler includes its own test cases and test
evaluation with the make check recipe.
Alongside the assembler, the gol-16 features a custom microcoding language: 'gmc' (gol-16 microcode). This microcode is 'assembled' by the fully custom mcasm assembler into FSM decode ROM and state ROM contents.
The schematic was created in Logisim Evolution, a community extended version of Logisim. If you install Logisim Evolution on your machine, you will be able load assembled gol-16 programs directly into the main memory ROM for execution by the built-in simulation.
This project is currently under construction.
