All Arria II GX memory blocks support shift register mode. Embedded memory block
configurations can implement shift registers for digital signal processing (DSP)
applications, such as finite impulse response (FIR) filters, pseudo-random number
generators, multi-channel filtering, and auto- and cross-correlation functions. These
and other DSP applications require local data storage, traditionally implemented with
standard flipflops that quickly exhaust many logic cells for large shift registers. A
more efficient alternative is to use embedded memory as a shift-register block, which
saves logic cell and routing resources.
The size of a shift register (w × m × n) is determined by the input data width (w), the
length of the taps (m), and the number of taps (n). You can cascade memory blocks to
implement larger shift registers.
