Lesson 1 - Design Creation Basics
The Xilinx DSP Blockset
The Xilinx DSP blockset is accessed via the Simulink Library browser which can be launched from the standard
MATLAB toolbar. The blocks are separated into sub-categories for easier searching. One sub-category, “Index”
includes all the block and is often the quickest way to access a block you are already familiar with. Over 90 DSP
building blocks are available for constructing you DSP system.
NOTE: It is important that you don’t name your design the same as a Xilinx block. For example, if you name your design
shared_memory.mdl, it may cause System Generator to issue an error message.
Each block has a background color that indicates the following:
Background
Color
Meaning
Blue Block Goes into the FPGA fabric and is free!!
Green
Block Goes into the FPGA fabric and is a Pay Core/Licensed. Go to the
Xilinx web site to purchase the Core license.
Yellow
Blocks on the boundary of your design like Gateway, Shared Memory
Read, Shared Memory Write, VDMA, etc
