Hello,
I have a simulink model processing data for EEG analysis and I need to have the results in real-time outside the PC to be inserted into an FPGA (Cyclone V by Altera). In particular I have 8 24-bit resolution signals out from simulink. How can I manage this interfacing?
What is the FPGA bus? How many channels, boud-rate (bps, bits second-¹), bit resolution and digital or analog?
A utopia would be a perfect match between your out-channels (from Simulink) to in-channels (Cyclone). That rarely happens. If that's your case, we'd need to design and develop a bridge bus to accomodate your data and hand-walk it to the other side.
I think you could use some NI DaqMx modul. They are quite easy to use because MAtlbab already implement toolbox for that.
However you have to well choose the modul according to the output frequencies of your signals. In addition with that kind of modul, you can use, in real time, an input feedback (from FPGA toward your simulink model) in order to make your model close loop style.
Hi,
You can cnvert your simulink code to HDL or VHDL code:
