# Overview

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][logisim-evolution] [schematic](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](schematic/microcode.gmc): 'gmc' (gol-16

microcode). This microcode is 'assembled' by the fully custom [mcasm assembler](schematic/mcasm.c) into FSM decode ROM

and state ROM contents.

The schematic was created in [Logisim Evolution][logisim-evolution], a community extended version of [Logisim][logisim].

If you install [Logisim Evolution][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.
