Implementing High Performance DSP Functions in Stratix & Stratix GX Devices
Each input register of the DSP block provides a shiftout output that
connects to the shiftin input of the adjacent input register of the same DSP
block. The registers on the boundaries of a DSP block also connect to the
registers of adjacent DSP blocks through the use of shiftin/shiftout
connections. These connections create register chains spanning multiple
DSP blocks, which makes it easy to increase the length of FIR filters.
Figure 7–5
Filters with more taps can be implemented by connecting DSP blocks in
a similar manner, provided sufficient DSP blocks are available in the
device.

The input data can be fed directly or by using the shiftout/shiftin chains,
which allow a single input to shift down the register chain inside the DSP
block. The input to each of the registers has a multiplexer, hence, the data
can be fed either from outside the DSP block or the preceding register.
This can be selected from the MegaWizard
as shown in
shiftout/shiftin flip-flop chains where the multiplexers are configured to
use these chains. In this example, the flip-flops inside the DSP blocks
serve as the taps of the FIR filter.
Adding the outputs of the two DSP blocks requires an external
adder which can be implemented using logic cells.
