Nucleus Embedded OS Support

The MCCI® Nucleus RTOS embedded operating system support package provides compatibility, performance, flexibility, and stability to the designer of Nucleus-based USB devices.

This technology integrates the MCCI USB DataPump® with Nucleus. It supports a large number of USB device controllers and virtually any CPU that is supported by Nucleus, allowing OEMs a simple integration path to a USB-IF certified USB device stack, for either 32-bit or 64-bit systems.

When the DataPump is combined with the Nucleus support for µITRON API, this package also creates an excellent platform for developing µITRON-based platforms.
