WebbIf that is useful I dunno. Like with the double buffers around the ffts is an extra 4k on the stack . I'm not using the TCM on the device either yes, and then the data access would be have to go through the cache. perhaps another 10%.... out of interest, my old sweetheart the ADI SHARC would do the 512 pt complex fft in perhaps 8000 cycles ?

Webb目前 ADI 主流的 DSP 是 Sharc 系列,其中的 ADSP-2146x 系列性能达到 2700MFLOPS, 与 TI 的 C674x 在 1k 点 复数FFT 的耗时都是 24us,针锋相对,旗鼓相当。 而 SC58x 的双核 DSP 里的 FFT 硬核加速器,只需要 5.5us 就可以完成了,比 TI 1GHz 的高性能 C66x 的速度 … Webbsharcは古くからある浮動小数点dspのせいか、複数のfft関数が用意されています。fft関数が複数あるのは、simd化で最適化されていたり、過去の互換性を保つためかと思うのですが、こういう声も聞こえてきます。「いったい何を使えばいいのねん!」そりゃ確かに。 WebbThe ADSP-SC58x and ADSP-2158x series consume less than 2 watts, making the new processor line-up more than 5x more power efficient than previous SHARC products. This advantage provides industry leading digital signal processing performance for applications where thermal management sets the limit for power consumption, or where the higher … northern lights whistler
