Behavior or fir_vec

Question asked by Tom00 on May 19, 2010

Hello

 

I have a question about the "Implications of Using SIMD Mode" for fir_vec.

 

Is my understanding correct?

            The number of input samples must be even.

                        Odd samples are processed in SIMD.

            The number of TAB's must be even.

                        Odd samples are processed in SIMD.

            All vectors must start with an even address.

                        Odd start addresses cause an error.

 

I found out the output of the fir filter was wrong, because the delay line started with an odd address.

 

-best regards

Thomas
