Memory Bandwidth Can Be and Issue

Acceleration via FPGAs in a simple form factor with easy to use software can be a real enabler for a wide range of computationally challenging algorithms. In many cases the memory bandwidth needed to keep the accelerator running can be the bottleneck. Hopefully this implementation provides some high-bandwidth memory interfaces that can keep the computation running at full speed.

Simulation vs implementation

Good to learn about the tool that assists in understanding how well the hardware acceleration would run by doing a simulation. I have not used such tools before, sorry for asking a dumb question. I understand it does simulation, but how does it also create the program files for FPGA, or does it support in creating the HDL code for implementing the code for the actual FPGA hardware also?

It would be interesting to hear from anyone with hands on experience with this tool. What's your application? How well does this serve it?

I wonder about the cost of the system?  It seems to be an interesting concept but I am not sure that it would be aimed at capturing a huge market.  I would think that the many FPGA development boards available from the vendors would provide a lower cost more portable design platform, but maybe at the cost of needing to learn VHDL or Verilog.  Seems to be a niche market product but it would be interesting to see how it compares cost and performance wise against a GPU board.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
