FX2 FPGA & ARM boards

The FX2 FPGA & ARM boards development boards are based on Xilinx/Altera FPGAs and Philips's ARM processor.
See for example“Xylo-LM”, “Saxo-Q”and “Dragon-E”.


Features
  • FPGA + optional ARM processor + digital IOs.
  • All boards: Controlled from USB-2 - no JTAG cable or power supply required.
  • Saxo-Q only: add four high-speed analog inputs and two high-speed analog outputs.
  • Dragon-E only: add a PCI Express interface. Check also this page.
  • Come with documentation, tutorials, source files and tools.
  • In addition of being development boards, they can be used as logic analyzers (using Chipscope or SignalTap) or analog acquisition systems (using a FlashyD daughterboard).

There are currently eight boards available.

(note 5)

Note 1: Boards are FlashyD ready (two high-speed analog inputs). FlashyD is sold separately.
Note 2: Not native, but FPGA JTAG-over-USB possible by soldering 4 wires on the boards.
Note 3: Five VGA IOs are shared with the IOs of the main board header.
Note 4: Micron SDRAM 16 Mbits (MT48LC1M16A1) and 64 Mbits (MT48LC4M16A2), or equivalents.
Note 5: Dimensions don't include the PCI Express connector.

Here's the family block diagram.
