example designs for Xilinx System Generator ?

[Timo Dammes]

Hello

As I'm a beginner with the Simulink tool, I'm very interrested in example
designs for System Generator. Can anyone post a link or something ?

I want to design filters which should run on a fpga (Xilinx Spartan 2
Xc2s200). But there are questions that the manual doesn't answer... (like :
how do I access data from the fpga board sram to put it to the filter)

Hello Timo

When you install Sysgen there are many demos that are included in
the install directory:
%my_matlab_install%\toolbox\sysgen62\xilinx\sysgen\examples
%my_matlab_install%\toolbox\sysgen62\xilinx\sysgen\examples\demos
There are a number of different filters included in the examples.

If you are trying to read data from external sram (?) then you could
use a memory controller to read data into the FPGA. If you are building
a parallel filter then the data is usually applied directly to the filter after
a
couple pipeline stages for performance. If you are using a MAC
structure then often you will want to use memory buffers to align your
data with your coefficients.

Xilins offers a classes that cover these topics in detail:

The classes are available in Germany and other places in Europe.

Cheers,
Elliot
