The application development begins with the FrameWork Logic code for the product you are

using. In many cases, the example application code provides a good starting point for your

application logic. In most cases the application logic shows a basic data flow between the IO

devices, such as A/D and D/A converters, to the logic and DSP or system. You can then build on

top of the example logic by inserting your algorithms into the data flow along with unique

triggering and other application-specific logic.

The FrameWork Logic provides a library of components for the hardware interfaces as well as

others functions, an example application showing IO interfacing and data flow, design constraints,

a simulation testbench, and a Xilinx ISE project or each example. This gives you the basic

foundation to begin work. After you install the FrameWork Logic on your system, you should be

able to recreate the logic and verify its operation. Once that is complete, you are ready to begin

development.

At this point, you should have a look at the example logic and determine the best place to insert

your logic and how you can best use the example in your development. If you can preserve many

of the basic memory mappings, controls and system interfaces, you will then be able to use the

example application software delivered with the product. That saves time for both you and the

software developers.

In most cases, you will see that the logic is organized as a hardware interface layer composed of

components that directly interface to the hardware and an application layer that is composed of

the analysis, data handling and triggering functions. The application layer is on a single clock

domain so that it is easy to integrate functions into the design.
