Programming and Libraries
The System Generator is a DSP design tool from Xilinx that enables the use of The Mathworks
model-based design environment Simulink for FPGA design. Over 90 DSP building blocks are
provided in the Xilinx DSP blockset for Simulink. These blocks include the common DSP building
blocks such as adders, multipliers and registers. Also included are a set of complex DSP building
blocks such as forward error correction blocks, FFTs, filters and memories.
