Embedded Linux Conference + Android Builders Summit

The presentation shows how Texas Instrument’s Keystone2 multicore ARM+DSP system on chip (SoC) works with the open source software radio package GNU Radio. GNU Radio is a popular package for developing software radio applications. Traditionally, GNU Radio has a General Purpose Processor (GPP) centric focus, however there is increasing interest accelerators signal processing operations with coprocessors. The Keystone 2 has general purpose DSP processors and some application specific coprocessors. Integrating co-processors with software running on the GPP must be careful to use low-overhead data passing schemes to avoid wasteful copies that can offset the gains due to the accelerator. This presentation will show how these co-processor can be integrated with GNU Radio. It will also cover some of the tool and work flow issues developing software for the DSP.
