What does the SDSoC #pragma mean??

Jump to solution

Hi 

 

I am studying an example of SDSoC.
I would like to know the meaning of the #pragma syntax of the HW function in the filter2d example.

 

#pragma SDS data buffer_depth("inoutUV.data":32768)

#pragma SDS data mem_attribute("inoutUV.data":NON_CACHEABLE|PHYSICAL_CONTIGUOUS)

#pragma SDS data copy("inoutUV.data"[0:"inoutUV.size"])

#pragma SDS data access_pattern("inoutUV.data":SEQUENTIAL)

#pragma SDS data mem_attribute("outLuma.data":NON_CACHEABLE|PHYSICAL_CONTIGUOUS)

#pragma SDS data copy("outLuma.data"[0:"outLuma.size"])

#pragma SDS data access_pattern("outLuma.data":SEQUENTIAL)

 

What documents should I look at to see what this phrase means?

 

thanks.
