DSPnano is an embedded signal processing operating system which is ported to SoC hardware and generally configured. As such, it requires more customization to meet final OEM needs and become a complete solution. As with iZoom! and Unison, all defects which are known can be searched and all forum support is included without cost. All DSPnano use includes two additional hours of support per year. After these hours are exhausted, further additional support hours may be purchased for each type of response and communication mechanism at current list prices.
