Booting the 56371 via serial EEPROM
Hello, I'm using the 56371 DSP and I have to boot it with serial EEPROM in I2C-Mode. The Procedure is described in the manual, but I do not know how to make a boot image from the *.cld file. I managed to make a .s file using srec.exe and then I converted that to intel hex format. Now, I don't know how to put the... 21 Sep 2006 12:44

ping: Jim Thompson
Jim, I was perusing your website and happened upon your patent regarding demodulating of FSK. Is this the currently easiest/best way to decode FSK? Or would I be better off doing with SW and microcontroller? I was thinking that a comparator with hysteresis to minimize noise could be used to 'square up' the inp... 26 Apr 2006 16:12

FFT in OpenCV
I use the function cvDFT in Visual C++. But i don't find the same Matlab 's result with the function fft2. Why? for the vector [0 0 1], Matlab return [1, -0.5+0.866i, -0.5-0.866i], and with the function cvDFT in OpenCV i have [1, 1, -0.5-0.86i] for the same vector. I don' t understand why. Please help me. ... 13 Mar 2006 09:15
