hi,

 

"Iircas5.asm file in the standard library dsplib_2.40.00 from Texas Instruments is not working, if the coefficients a1, a2 used in the file is more than one.
are you planning to correct this mistake and update this library file?

    I would suggest you utilize a subject that is a little more descriptive of the issue than your name.

     

    Please take a look at the TMS320C55x DSP Library User's Guide found on the product folder for the TMS320C55x DSP Library.

    You will find that the DSP library is implement in Q0.15 format where Qm.n is defined as m=represents the 2's compliment integer portion of the number and n=represents the 2's compliment fractional portion.

    This means the 16-bit number expresses a signed number between positive and negative 1.
