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 ?

WebbThe DAGs in the SHARC DSPs are also designed to efficiently carry out the Fast Fourier transform. In this mode, the DAGs are configured to generate bit-reversed addresses into the circular buffers, a necessary part of the FFT algorithm. Webb目标跟踪histogram是一个24位的灰度数组，长度是2的24次方。此函数用于统计24位彩色图像的直方图（但这并不是一个能够独立使用的函数，有全局变量）， 方法是定义了一个移动的跟踪窗口（trackwinwidth x trackwinheight). greffe nanterre telephone
