3.4.4. Internal Coefficient for Fixed-Point Arithmetic

The Intel® Arria® 10 variable precision DSP block has the flexibility of selecting the multiplicand from either the dynamic input or the internal coefficient.

The internal coefficient can support up to eight constant coefficients for the multiplicands in 18-bit and 27-bit modes. When you enable the internal coefficient feature, COEFSELA/COEFSELB are used to control the selection of the coefficient multiplexer.
