Would softfloat be good enough? If the clock speed is sufficient, the lack of floating-point hardware may not matter much. It obviously isn't ideal, but it'd work. That said, having a small floating-point "DSP" might be a good way to go too, let the on-board ARM CPu do all the user interface stuff and offload the serious RF work to another processor. > We have two hardware platforms that I think we can display.

I suppose a device here would be more like a chunky 8" tablet: with a decent battery in the back and a fairly large touchscreen -- which could be a plus for usability. -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere. ------------------------------------------------------------------------------ Precog is a next-generation analytics platform capable of advanced analytics on semi-structured data.
