hello ,

 

We use Arria10 on our customer board. 

 

In our System, we need implement mSGDAM Core to transfer a bundle of 128 descriptors for data moving from cpu to fpga device .  I checked " ug_embeded" user guide, but still not clear about  " HOW can mSGDMA perfetch IP realize this  "。 What's the procedure to implement this ? 

 

Is there an exampel for mSGDMA prefetched enabled  design ?  We use Linux on CPU 。

 

Thanks in advance ~
