Signal Name
Variable Precision DSP Block Control Signals
The Stratix V variable precision DSP block has a total of 14 dynamic control signal
inputs. The variable precision DSP block dynamic signals are user-configurable and
can be set to toggle or not at run time.
Table 3–5 on page 3–22
Stratix V variable precision DSP block supports 18-bit and 27-bit input cascading.
