Ideally, an architecture-aware scheduler could capitalize on all available accelerators / heterogenous processors, and could maximize performance for that system.
Unfortunately right now we're limited to porting a subset of blocks to these accelerators.

Or possibly more interesting and significant for the future, heterogeneous processors in a system. We're seeing lots of this with ARM's on FPGA's, GPU on ARM based SoC, ....... In addition to homogeneous multicore processors with interesting network fabrics........

Yes. We certainly need to get blocks ported over to the chip to do
anything. From a GNU Radio standpoint as a GSoC project, that's not
particularly interesting to us, just work that has to be done. What
we're interested in as a project is improving our understanding of
both many-core processors as well as the use of coprocessors for
signal processing/SDR work.
