2.2. Pipeline Registers for Fixed-Point and Floating-Point Arithmetic

In addition to the input and output registers, there are 2 columns of pipeline registers for fixed-point arithmetic. Pipeline registers are used to get the maximum Fmax performance. The pipeline registers can be bypassed if high Fmax is not needed.

The following variable precision DSP block signals control the pipeline registers within the variable precision DSP block:
  • CLK[2..0]
  • ENA[2..0]
  • CLR[1]

Floating-point arithmetic has 3 latency layers of pipeline registers. You can bypass all latency layers of the pipeline registers or use any one, two or three layers of pipeline registers.
