Infinite Impulse Response (IIR) Filters
7–38
Stratix Device Handbook, Volume 2
The first DSP block in
adder mode, and the second DSP block is in the four-multipliers adder
mode. For an 18-bit input to the IIR filter, each biquad requires five
multipliers and five adders (two DSP blocks). One of the adders is
implemented using logic elements. Cascading several biquads together
can implement more complex, higher order IIR filters. It is possible to
insert registers in between the biquad stages to improve the performance.
