9 years ago --- Quote Start --- Thanks for the info. I think i will try it. Even if I'm a bit scared because the last time passing from the beta to the official release Nallatech had the idea of changing the name of the board making unusable binaries that required hundreds of hours of cpu time to build them up. grazie --- Quote End --- Now I'm scared to update definitely BSP. One first result I got from a precompiled fft1d binary is that it is 30% less performant : with new BSP R001.004.0002 Using AOCX: fft1d.aocx Reprogramming device with handle 1 Launching FFT transform for 2000 iterations FFT kernel initialization is complete. Processing time = 5.7592ms Throughput = 1.4224 Gpoints / sec (85.3449 Gflops) Signal to noise ratio on output sample: 137.677661 --> PASSED Launching inverse FFT transform for 2000 iterations Inverse FFT kernel initialization is complete.
