Cyclone III Device Family
December 2011
CIII51005-2.3
CIII51005-2.3
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.
