4–13:
In the high-precision multiplier adder, the DSP block can implement 2 two-multiplier
adders, with a multiplier precision of 18 × 36 (one two-multiplier adder per half-DSP
block). This mode is useful in filtering or fast Fourier transform (FFT) applications
where a datapath greater than 18 bits is required, yet 18 bits is sufficient for coefficient
precision. This can occur in cases where data has a high dynamic range. If the
coefficients are fixed, as in FFT and most filter applications, the precision of 18 bits
provides a dynamic range over 100 dB, if the largest coefficient is normalized to the
maximum 18-bit representation.
