Is it possible to get a copy of the FX3 firmware sourcecode used in this performance video ?

   

Thanks.

Hi,

   

I agree - it would be a good idea  to get the throughput firmware. With the existing SlaveFifo firmware the maximum bandwidth I have seen is 127MBs. It would be good to compare the two.

Youn can simply change the Slave FIFO example to 16 packets per Burst and DMA Auto Mode to achieve transfer rates of ~320MB/s (on PCI 2.0 Host controller and 100MHz PCLK).

Chris_R,

   

I tried what you suggested and I still could only get around 127MBs. I will try this on a x64 Win 7 machine  sometime, but for now my limit is 127MBs. So it would be good to get a look at the throughput performance firmware.

Do you have a PCI 2.0 USB 3.0 host controller installed? With my HP (PCIe 1.1) machine I also can reach only ~130MB/s.

I mean PCIe 2.0

In a PCIe 1.0 computer I was getting 90MBs while on a PCIe 2.0 computer I got the 127MBs. I had other problems with the FX3 and did not have time to look further at the data bandwidth issue - also 127MBs is enough for now but I would like to see how far this can be pushed. It would be good to know what data bandwidths other people are seeing.

It was a beta code used just for that testing. I've raised a request to add this part of the SDK. Will keep you guys posted on when it'll be available for download.
