RoweBots Research, Inc. has rolled out two ultra-tiny embedded-Linux compatible RTOSes that opens Renesas Technology Corp.'s R8C, M16C and R32C/100 MCU families to Linux and POSIX compatible development for the first time.

DSPnano is the functional equivalent to an ultra-tiny embedded-Linux RTOS for Renesas' 8- and 16-bit MCUs, including the R8C and M16C. Used with the High-Performance Embedded Workshop (HEW) IDE, DSPnano increases embedded development productivity and reliability.

Typical applications range from tiny printer engines to demanding automotive control. By using these off-the-shelf products with the R8C and M16C MCU products, OEMs can save substantial development time and reduce development risks through software reuse.

Unison, the 32-bit RTOS, is targeted for home automation and networking applications. Unison increases embedded development productivity and reliability for R32C/100 developers by substantially reducing the difficulties of developing complex systems.

OEM developers can create improved applications with reusable components supported by the Unison product and Renesas R32C/100 MCUs with HEW IDE. Complete networking protocols are also available.

DSPnano and Unison are designed for Renesas MCU development by engineers who value reduced design complexity and getting to market quickly.

DSPnano and Unison support the entire range of Renesas MCUs, from 8- to 32-bits, and are intended for use in OEM environments where time to market and multiple products using the same software platform are a requirement. Software can be migrated between architectures without code changes, opening up tens of thousands of applications on these embedded platforms, according to the company.

The ultra-tiny Linux offerings provide integrated MCU RTOSs with full POSIX and Linux capabilities in a tiny footprint to minimise training time and processor size; complete off-the-shelf I/O including networking and file systems; and free development and source code. They integrate seamlessly with the Renesas HEW ID.

DSPnano and Unison can be used with Renesas R32C or R8C/M16C MCUs using open source technology available on the RoweBots Research website.

Unison V4 and DSPnano V2 are hosted on Windows XP and Vista for x86 platforms. Support, training and consulting for the entire Renesas R8C, M16C and R32C/100 MCU line are available.

DSPnano and Unison V4 are shipping now, with free development offered. Open-source royalty-free licences start at Rs.2.02 lakh ($3,995 USD).
