4. Embedded Multipliers in the

Cyclone III Device Family

The Cyclone® III device family (Cyclone III and Cyclone III LS devices) includes a

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.
