You can use DSP for all kinds of calculations. It is a general purpose processor optimized for DSP applications. So yes, even floating point things will work, although performance will not be great.

Not applicable to ARM devices, but for people landing here after searching for “DSP” and “OpenCV,” for high performance on x86-based servers, the TI c66x processor series, which has 32-bit fixed and floating instructions, is a good choice. OpenCV has been ported to c66x accelerator cards and works without problems:
