DSP intellectual property (IP) cores
DSP Builder interface to The Mathworks Simulink and Matlab
design environment
DSP Development Kit, Cyclone II Edition
Cyclone II devices include a powerful FPGA feature set optimized for
low-cost applications including a wide range of density, memory,
embedded multiplier, and packaging options. Cyclone II devices support
a wide range of common external memory interfaces and I/O protocols
required in low-cost applications. Parameterizable IP cores from Altera
and partners make using Cyclone II interfaces and protocols fast and easy.
