Sundance SMT381 2007 - Manual (Page 21)

7 Support Packages
The SMT381 can be coupled with several base modules. Example applications are
provided for each base module.
The examples are developed with 3L Diamond DSP and FPGA design tool.
Source code for the software and firmware tasks is provided. The tasks can be re-used
by users to implement their own applications.
The following sections describe the examples provided for each one of the base boards
available with the SMT381.
7.1 SMT368A
The FPGA uses a Look-Up-Table to generate a sine-wave that is then played out by the
DAC. The sampling frequency and other parameters of the SMT381 are controlled via
software.
The example uses a DSP module to run the software tasks. The base module is a
SMT368A.
In the example, the FPGA sends the samples for a sine-wave to the DAC. The DSP is
used to configure and control the SMT381 and its base module.
The diagram shows the tasks used in the example and their interconnection.
The task in yellow runs on the DSP of the SMT395; the tasks in blue run on the FPGA of
the base module.
