Hello, I spent some time working with the F765 chip evaluating Codec2 (everything above 700). Did you try putting all memory used by Codec2 into the TCM RAM? It made a huge difference when I was testing.

After being stopped for while by a bug in the STM supplied data cache init code I was able to get the OVI40 TRX to transmit for a brief moment the FreeDV sound to my RX. But unfortunately the STM32F7 is not fast enough to transmit 700D continuously. It is simply not able to produce a 160ms frame fast enough. Can't say anything about receive yet, but I can see also a serious load when in RX. Next up is to run the same code on a STM32H7, I have some hope that this one is fast enough with the code as it is (it is about twice as fast the STM32F7 clockwise). 73 Danilo ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Freetel-codec2 mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/freetel-codec2 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Freetel-codec2 mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/freetel-codec2
