GNU Radio/Parallella project for GSoC 2013

Hello, I’m starting this thread to discuss ideas about
support for many-core floating-points accelerators.
As it was said in wiki it could be for example:
-further development of Performance Counters
and Block Core Affinity
-implementing message passing using on-chip networks

Shouldn’t we work on actually running any of the blocks on the
accelerator before trying to benchmark them ?

Cheers,

Of course, but the suggestion was that a GSoC project involving
Parallella should do more than just port blocks this could be part
of the project but not all. I believe Tommy T. II has started
working on porting, but I am not sure how far he will get before a
student would need to start their project.

Cheers,

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…

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.

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.
