= gr-fosphor GNU Radio block for RTSA-like spectrum visualization using GPU http://git.osmocom.org/gr-fosphor/ == Screenshots === osmocom_fft in fosphor mode [[Image(GrOsmoSDR:fosphor.png)]] [[Image(GrOsmoSDR:fosphor2.png)]] == Bandwidth figures There's a benchmark program available which allows to estimate the maximal bandwidth that can be processed with a specific GPU. To build it: {{{ cd gr-fosphor/lib/fosphor make }}} Then execute it by providing a prerecorded complex float file (a couple of 100MB should be fine) in gnuradio format. {{{ ./main some.cfile }}} Try to leave the window to its default size if possible and watch out for the Msps numbers printed out to the console & submit them to us. ||'''GPU'''||'''Msps'''|| ||AMD Hawaii||WANTED|| ||AMD Tahiti||~220|| ||NVidia Titan||WANTED|| ||NVidia NVS 140M||~14|| NVS140||~10|| ||NVidia ION||~10|| ||NVidia GT330M||~22|| ||NVidia 8600GT||~15|| ||NVidia 9600M GT||~31|| ||NVidia GT330M||~22|| ||NVidia GTX 550 Ti||~97||
