Implementation of a PC-based motion controller/robot controller with USB interface [4]

USB Comminication speed between a host computer/board and the motion-control FPGA.

1. Experiment setup.  

  • 1530-byte round-trip test.
  • Asynchronous FIFO mode of the FT2232H.

2. Experiment results.

  • PC running a plain Linux: about 50 Mbits/sec.
  • Raspberry Pi 2 running a realtime Linux:  at least 30 Mbits/sec.
