RSS Bot Posted December 21, 2009 Share Posted December 21, 2009 I've finally finished (and debugged) my Fast Discrete Hartley Transform for the Propeller. It takes 2^N signed 32 bit input samples and produces the output in the same array. I've measured the following: 16 samples in 12,496 clock cycles 64 samples in 87,648 clock cycles 256 samples in 534,656 clock cycles 1024 samples in 2,899,504 clock cycles 4096 samples in 14,668,112 clock cycles At 80MHz that's 27.5 1024 sample DHTs per second! http://www.atariage.com/forums/index.php?app=blog&blogid=7&showentry=6684 Link to comment Share on other sites More sharing options...
