FSL link beginner question

Hello

I have added manually the Peripherial described in the following document to my system. And there were really output results, so it worked quite good.

The next step was, that I altered the entity iDCT, so that it only performs a simple xor operation.This was the only change! But unfortunately the output value is always 0, so can somebody perhaps tell me what went wrong in this example? The IP should be added correctly to the Microblaze processor, is it perhaps possible that I have to set the Data_Out_Valid signal

You have to handle the other signals in the protocol like the data_in_valid,... You also have to set the Data_Out_Valid when you actually have valid data.

Hi

Thanks for your answer

Well I am a real newbie, so I have a ask again what do you mean exactly. So I need a state machine to manage this simple operation?

First of all I have to set the data_in_valid You also have to set the Data_Out_Valid when you actually have valid data.

You should download EDK 6.3i where you can do this automatically in the tools. The tools will insert a dummy function where you can change one line for this type of function you want to do.
