9. Functional Description of the Drive-On-Chip Design Example

The design consists of two main elements: Qsys, DSP Builder for Intel FPGAs, IP, and RTL sources compiled into an FPGA programming file; and C source code compiled to run on an Arm Cortex-A9 in the HPS in the FPGA.

The Qsys system consists of:

  • Processor subsystem
  • DC link monitors
  • DC-DC converter
  • FOC subsystem
  • FFTs
  • Two motor drive axes comprising the following motor control peripheral components:
    • 6-channel PWM
    • Drive system monitor
    • Quadrature encoder interface
    • Resolver SPI interface
    • ADC interface
