PitchNancy Posted February 28, 2005 Report Share Posted February 28, 2005 Hello, With my pxi FPGA and RT 8186 controller I obtain only 20 kHZ of loop rate. I use IRQ method and acquire 8 analog input. I make for the moment no processing on FPGA and RT. Can you say me if you have similar results or better ? Quote Link to comment

I have used the real time system manager to evaluate the CPU usage. I have acquired 8 analog Input with FPGA and transmitted them to RT by the IRQ method. I did the test for cluster, array, and 8 single channel transmission. After 20000 Hz the RT CPU usage was superior than 100 %, and bug. I attach my VI and my results.
