This routine implements a DF 2 transposed structure of the biquad filter
@param x Pointer to input samples
@param b Pointer to Nr coefs b0, b1, b2
@param a Pointer to Dr coefs a1, a2
@param delay Pointer to filter delays
@param y Pointer to output samples
@param nx Number of input/output samples
- Algorithm:
- DSPF_sp_biquad_cn.c is the natural C equivalent of the optimized linear assembly code without restrictions. Note that the linear assembly code is optimized and restrictions may apply.
- Assumptions:
- The value of nx is >= 2.
- Implementation Notes:
- Interruptibility: The code is interruptible.
Endian Support: The code supports both big and little endian modes.
