The SAPHO Ecosystem

SAPHO
Simple Architecture for Processor Hardware and Organisation

A RISC-inspired 16-bit processor architecture designed for FPGA implementation and used in the DLP discipline at UFJF. Includes the CMM high-level language, a Verilog HDL implementation, and a complete digital design toolchain.

GitHub Project Page
YANC
Yet Another NIPSCERN Compiler

Two-stage compiler toolchain for the SAPHO architecture. cmmcomp translates CMM (C-like) source code to SAPHO assembly; asmcomp assembles to machine code. Distributed as a self-contained executable.

POLARIS
Cross-platform IDE for SAPHO

Lightweight IDE for the SAPHO ecosystem. Runs on Linux and Windows. Includes YANC integration, YAWT built-in wave tracer, PRISM RTL viewer, and Monaco Editor. Starts in under 1 second and uses ~60 MB of RAM.

AURORA
Legacy
Windows-only Electron IDE for SAPHO

The original Electron-based IDE for SAPHO (v1.0–v4.27.10, 2021–2023). Archived. Succeeded by POLARIS. Repository preserved for historical reference; includes 25 releases across two development years.
