Just FYI, I have an OOT with FFT blocks running on the C66x DSP
with the Beagleboard X-15.

This is with OpenCL and Ubuntu 18.04. The performance was not
great (worse than FFTW running on the ARM) which may be due to
OpenCL overhead.
The Ubuntu 18.04 console image is only 1.3 GB.

Ubuntu 20.04 is also available.

@JM, I'm curious to here about future results with
rpmsg and pre-processing on the M4. I've a GNURadio setup on a
TI AM5728 (Cortex A15) processor that has dual core M4's and
dual C6x DSPs. Haven't had any free time lately, but have been
interested in how the M4s and DSPs could accelerate some of the
processing in GNURadio via remoteproc/rpmsg.
@Philip, hopefully ST's yocto BSP supports x11, TI's yocto
is wayland only and I have been unsuccessful getting GNURadio,
X11, TI Yocto BSP and other requirements to all play nice. It
has left me sour on anything Yocto.
