Good morning, does anyone have C code using cbrev() and rfft() functions of DSP lib? I have noticed that the example given in \examples\rfft, referred on SPRU518C, page 4-69, calls rfft() right after calling cbrev(). There is something wrong here, as cbrev(

Hello! Does someone knows how to convert a q31 value to a q15 value? I=B4m=20=20 doing a power of a vector, using the power function od DSPLib, but the=20=20 results is on q31 format. After, I need to do a sum, but the add=20=20 function only accept q15 values. Could anyone help me? Thanks a lot, Guilherme =20

hi all, I just want to implement a iir filter on 5416 dsk for i implementing lpc10 vocoder. This vocoder i have implemented on MATLAB and its time for me to port the code in target. For implementing the filter, i want to make use of dsplibrary functions, but the coefficients which i need to pass to the function is fixed point 16 bit data, matlab gives coefficients in floating point mode...

Hello Everyone!   I'm working on DSP, TMS320C5402 specifically, and I'm newbie on this subject...   I need to implement a realtime IIR filter on DSP... can I use DSPLib to realtime process the samples?   If so, why does the input (x[nx]) variable is an array? Once it uses the Direct Form 2,
