-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Junaid,
such a system already exists in the shape of a xilinx zynq board. There's been a talk that (although I was not there to witness it) is supposed to be quite good: https://fosdem.org/2014/schedule/event/gnu_radio_hardware_acceleration_on_xilinx_zynq/ I'm not sure if videos of that talk are available at this point. However, there is quite a documentation in the GR wiki: http://gnuradio.org/redmine/projects/gnuradio/wiki/Zynq For usage of specialized DSP instructions (if these can be part of the normal CPU program) please have a look at VOLK, which is a part of GNU Radio: http://gnuradio.org/redmine/projects/gnuradio/wiki/Volk Greetings, Marcus PS: Have to slightly disagree with you on the "hardware is faster than software, always" part, since design constraints usually limit the performance of FPGAs, and moving data guaranteeing coherence comes at a performance penalty.
