FPGA-to-HPS bridge, too slow?

Hi, my co-worker is using the Cyclone V with the embedded ARM cores. I often stop by his cube and ask him his opinion of the SoC. His biggest complaint is the FPGA-to-HPS bridge which he says is a bi...

Hi and thanks for responding to my post. The FPGA will interface with a Analog Devices TigerSharc through its Link Ports. The FPGA side implements the Link Port Interface and then passes the received data to the HPS side.

Is anyone else experiencing this type of behavior over the HPS bridge?

Thanks
