interfaces that help increase performance, reduce system cost, and lower the power
consumption of digital signal processing (DSP) systems. Cyclone IV devices, either
alone or as DSP device co-processors, are used to improve price-to-performance ratios
of DSP systems. Particular focus is placed on optimizing Cyclone IV devices for
applications that benefit from an abundance of parallel processing resources, which
include video and image processing, intermediate frequency (IF) modems used in
wireless communications systems, and multi-channel communications and video
systems.

multiplier or two 9 × 9 multipliers. For multiplications greater than 18 × 18, the

are no restrictions on the data width of the multiplier, but the greater the data width,
the slower the multiplication process.
