What the difference from Altera-SoCFPGA-HardwareLib-DMA-CV-GNU ?

[ranshalit]

Hello,

I see in readme that example Altera-SoCFPGA-HardwareLib-DMA-CV-GNU is mentioned (though could not find it in my 14.1 EDS).
So, what is the difference between the above example and this GIT example ?

Thanks!

I do not remember from where I downloaded example. I think it was from https://rocketboards.org/ but I do not remember. I rememeber that i split DMA preparation and transfer so it the transfer for my example should be faster (in the original example the DMA controller microcode is prepared in every transfer).
