problem in using optimal DSPF_dp_biquad

Started by rex...@g-tech-inst.com June 6, 2006
hi all..

Is there anyone who also has problem in using DSPF_dp_biquad?
My develop environment is Code Composer Studio 2.2, and I included dsp67x.lib and DSPF_dp_biquad.h into my project.
Then I try to execute the DSPF_dp_biquad function and compare with the result of Matlab.
While using the optimal version, it turns out different result to Matlab.
With using the dsp67x_sa.src, I could get the same result.

It is tricky. Is it a bug? Or I miss some detail setting?
I would like to develop a real-time system. The non-optimal function will be the last choice.
