The RTG004 is a self contained system combining FPGA hardware and a programmable embedded PowerPC. It also offers two banks of DDR SDRAM with a 3.2Gbytes total memory bandwidth. VHDL support is included for connecting this DDR memory to the Embedded PowerPC processor AND your VHDL design at the same time.

16Mbytes of FLASH memory is connected to the FPGA - intended for PowerPC code storage.

The system can be used stand alone or connected to a PC via the USB 2.0 connection.

The FPGA can be programmed with your own design, allowing whatever function you need, and connectivity to the embedded PowerPC processor. This allows you to develop an embedded design that uses FPGA hardware and PowerPC processor in the correct mix for your particular needs.

The USB connection is supported via the HUNT ENGINEERING Host-API software. This allows software applications and tools on the Host PC to access the hardware using a consistent software interface without the need to understand or program the hardware or USB directly.

The FPGA program can be loaded over the USB connection using a software tool that directly accepts the output from development tools for the Xilinx FPGA. Alternatively a Xilinx JTAG cable (Parallel or USB) can be used to load the FPGA and or program the on board configuration PROM. The PowerPC program can be downloaded as part of the FPGA design or after the FPGA configuration using the GNU debugger or the HERON FIFOs or can be loaded from the FLASH memory provided on the module.

The FIFO connections can be used to stream data between the PC and the FPGA. They are capable of up to 50Mbytes/second in each direction, but the Host PC, its USB controller and the operating system will all impose their own limits to this speed.

The system is delivered ready to go with a power supply (requires an IEC lead specific to your country), USB cable, I/O cables and a CD with all of your documentation, software tools and examples. The only other thing you need are development tools for the Xilinx FPGA, for example Xilinx Foundation ISE from www.xilinx.com and  Xilinx EDK for programming the PowerPC.

Technical Specification

• FPGA

  Xilinx XC2VP7 Virtex-II Pro - FPGA logic with PowerPC hard core 
  With no heatsink fitted (standard) the FPGA can dissipate 2.4 Watts at 50deg C ambient temperature.
  The power circuits are capable of delivering more than this, so a heatsink may be required for your design.
  If that is the case a larger 5V Power Supply Unit may also be necessary

• Memory

  DDR SDRAM 256Mbytes organised as two banks of 32M x 32 at 200Mhz
  Flash 16Mbytes - byte wide

• Host Bus

  USB 2.0 capable of up to 50Mbytes/second dependent on host PC and USB configuration.

• Maximum Dimensions:

  160mm x 110mm x 21mm.

• Power requirements

  5V Max: 1.55A plus the power taken by the FPGA. Typ: 1.15A plus FPGA
  The Mains Power Supply Unit included can supply up to 4A, which is enough to power an FPGA design that is less than the 2.4W bare package maximum dissipation.
