Development Board Ideas:

  • A/D and D/A module
  • Audio and Video module
    • Low impedance speaker connection (Positive and Negative Banana Outputs).
    • Phono jack for headphones, personal computer (PC) speakers, or external audio mixer.
    • Analog HD-15 RGB Video Output Connector for interface to analog crt monitors or projectors.
    • Analog HD-15 RGB Video Output Connector for interface to camcorder, VCR, or other video source.
    • Digital DVI Video Output Connector and DVI Transmitter for interface to digital flat panel/lcd monitors or projectors.
    • Digital DVI Video Input Connector and DVI Receiver for interface to a PC graphics card, digital camcorder, or other digital video source.
  • MP3 module
  • IEEE-488 General Purpose Interface Bus (GPIB) module
  • USB 2.0 module
  • Fire-wire (IEEE-1394) module
    • The specifications for this interface are located on the group file server. For more information contact me, and I'll give you directions on how to access the spec's.
  • Integration with purchased demo boards:
    • If we purchased a Xilinx ML310 demo board, then we could design our own personality module with AsAP processors/chips on it for interface with SDRAM, PCI, and USB. This would allow us to test multiple AsAP chips using the same host test system. We could even design different variations of the personality modules.
      • For example, we could have one board that had Low-Speed / High-Precision A/D and D/A, and another that had the High-Speed / Low-Precision A/D and D/A.
      • We could make it even more efficient if we designed a single board that had different stuffing options. This would save in the fabrication costs. We could have the AsAP processor loaded on all fabricated boards, and then load the desired A/D and D/As on the boards locally in the VCL lab.
      • We would need to verify power consumption requirements of future personality modules, and compare against the provided power (voltage/current) from the Xiliinx ML310 board.
    • One problem with this design is that it would force us into using the ML310 boards; however, we could design in other hooks to power the board independently of the ML310 board.
      • For example, we could have dc power connections, local regulation, USB/Fire-wire interface (with included FPGA/controller), and a switch that allows us to switch between ML310 and individual operation.
    • The ML310 interface provides a convenient connection to SDRAM and PCI. We could use the Virtex-II Pro on the ML310 for all interface control between a host system (PC running Linux or Windows OS).
