3.1.2. Digital Signal Processing (DSP) Block
A digital signal processing (DSP) block implements specific support for common fixed-point and floating-point arithmetic, which reduces the need to build equivalent logic from general-purpose ALMs.
The following figure illustrates a simplified three-input DSP block consisting of a multiplier (×) and an adder (+):
The following figure illustrates a simplified DSP block:
