Hi, I am working on doing background subtraction with DE2 development board and I want to do a noise filtering using the median filter 2D megacore function which comes with the quartus II 11.1sp1 Web Edition. Somehow, I couldn't get the things work. Thus, I have a few questions as below and really hope if there is someone who can help me on this cause I am already lack behind of the development progress.
1. Does it need a specific license to generate the median filter 2D file(verilog) properly?
2. How does the module really works with its input and output signal? There is an output signal DIN_ready which I suppose it should signifies the module when it is ready for input but somehow it is always 0.
3. I got the median filter 2D verilog file generated but it starts with a comments
generation: deferred. Is this normal? The comments are as shown below.
// megafunction wizard: %Median Filter 2D v11.1%
// generation: deferred // synthesis translate_off
Really there is anyone who can help me on this. Thank you in advanced!:)
