GeMRTOS is free to download. Uncompress the archive and copy the /ip subdirectory into your Quartus® Prime project folder — GeMRTOS then appears in Platform Designer as a component you can add like any other IP.
Built with Quartus® Prime Standard 23.1 for MAX 10 devices; Agilex 3 designs use the Quartus® Prime Pro edition — the edition follows from the device. Targeting Nios V soft processors. Nios II is supported as a legacy route.
What is in the download
- The GeMRTOS controller and kernel as Platform Designer IP components.
- Eleven worked example applications, each with an automated output check.
- A Windows simulation layer, so you can run the examples and explore the API before you have a board.
- Build and deployment scripts, and the user and development manual.
The eleven examples
Each example is a complete, buildable application. They are ordered so that each one introduces a single new concept.
| Example | What it demonstrates | Needs |
|---|---|---|
| 01 — Hello task | The minimum viable application; board smoke test | — |
| 02 — Tasks and delays | The task model: periodic and one-shot, priorities, offsets, suspend and resume | — |
| 03 — Semaphores | All four semaphore flavours, timeouts, priority-ceiling protocol | — |
| 04 — Dining philosophers | Contention and deadlock avoidance at scale | LEDs |
| 05 — Message queue pub/sub | Message queues as publish/subscribe, fan-out, late subscribers | — |
| 06 — Triggers and ISR | Hardware triggers and ISR-as-task on a real interrupt | — |
| 07 — Multiprocessor scheduling | Partitioned, global and exclusion-limited scheduling side by side | Two processors |
| 08 — Signals and frozen mode | Deadline-overrun and system-backlog fault handling, self-recovering | — |
| 09 — Network HTTP server | lwIP with an HTTP server, SSI/CGI and AJAX | Ethernet, LEDs |
| 10 — Full demo | Everything combined; the regression reference | Ethernet, LEDs |
| 11 — Watchdog recovery | Per-processor watchdog fault recovery: a hung task is caught, its processor reset and recovered automatically | Two processors |
A board without Ethernet cannot run 09 or 10; a single-processor system cannot run 07 or 11. Everything else runs anywhere, including in the Windows simulation.
Board and kit demo projects
- MAX 10 FPGA — the reference platform. The full example catalogue is delivered and exercised on this board.
- BeMicro SDK — Cyclone IV E board project.
The networked demo also runs on the Atum A3 (Agilex 3) board, over gigabit Ethernet with DHCP. That board project is not among the downloads.

About the licence file
The GeMRTOS IP core is delivered encrypted, so Quartus® Prime needs a FlexLM licence file (.dat) to use it. The download includes both a fixed licence, for a single machine, and a float licence, for a licence server shared by several workstations. Both work with any network adapter.
If you already run a FlexLM server for other IP and want to add GeMRTOS to it, a licence tied to that server’s network adapter can be issued on request — we need the MAC address of the machine running the FlexLM server, the same detail Altera asks for when issuing licensed Quartus® Prime.
