The only unfortunate limitation on the Cyclone is the absence of floating point, which might be a (big) issue sometimes.
I'm curious if there is any FPGA which has native floating point support. My understanding was that the nature of an FPGA was to provide low level logic resources - if you need floating point, build it out of the gates/registers/etc that are provided.
That said, I've found very few cases where the dynamic range of full floating point is required in RF/communications front-end processing. I've seen block floating point used in hardware FFTs in the past, but seldom in other applications. Most demods are dealing with so much noise and distortion to begin with that floating point would be, well, pointless.
