The Cyclone
combination of on-chip resources and external interfaces that help to increase
performance, reduce system cost, and lower the power consumption of digital signal
processing (DSP) systems. The Cyclone III device family, 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 III and Cyclone III LS
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.
