The gnuradio-core directory src/lib directory contains directories that contain signal processing code, such as filter, and a directory , src/runtime, that contains the basic component "framework" classes that handle block creation and connection. The code in src/runtime does not appear to have any FPU dependencies. It seems that a serious effort to build gnu-radio for a new processor would involve adding new filters that operate on a fixed point quantity and optimized for specific instruction sets (ARM dsp extensions, wMMX, DSP comprocessors, etc). The turning off compilation of the floating point structures. I also see that gnu radio implements each filter several different ways, depending on the input/output/tap data types. Why doesn't gnu radio use some kind of adaptive typing so you can have one block process many data types? Hopefully this makes sense, I did most of this thinking on the plane back from FOSDEM with a nasty head cold.
