HERON-FPGA12 is supplied without cables as standard. However, some cables can be supplied included in the hardware price, if required. Please specify at time of ordering either up to two FPGA50 or up to two FPGA50-CameraLink-IN cables. See HERON-FPGA12 cables for more information.

The HERON-FPGA12 provides a user programmable element for a HERON system that combines FPGA hardware and a programmable PowerPC. The PowerPC can be connected as part of the FPGA design allowing users to choose the best mix of hardware and software to perform the signal processing they need.

The module offers 128Mbytes of DDR SDRAM with 1.6Gbyte/sec total memory bandwidth. This off chip memory can be accessed by the PowerPC processor core and also from FPGA logic at the same time (arbitrated). The provided Hardware Interface Layer (HIL) VHDL includes a DDR memory controller that can be connected to user FPGA logic and the PowerPC ODB at the same time.

There is a 16Mbytes FLASH memory connected to the FPGA which is intended for storing boot code for the PowerPC. There is a Xilinx provided Core that allows this to be connected to the PowerPC directly, but the user can choose to connect their own VHDL to the FLASH memory if their application requires.

The module offers 60 bits of digital I/O, which can have series resistors fitted at build time to allow 5V tolerance. these I/Os can be configured by the FPGA design to use any Virtex-4 format that uses 3.3V Vcco. It should be noted that this means LVDS inputs are an option but not LVDS outputs. 

HERON-FPGA modules must be fitted to a HERON module carrier that provides power and control signals to the module. Most module carriers also offer FIFO based connections between modules and possibly between the modules and a host PC. Normally the configuration program for the FPGA is sent from a host PC via the Heron Serial Bus, allowing fast development, test, debug cycles as well as in-field upgradeability. Alternative ways of configuring the FPGA are the on-board FLASH based configuration PROM, and the JTAG header that accepts standard Xilinx JTAG cables such as Xilinx Parallel cable 4 or USB-JTAG cable.

After configuration the Heron Serial Bus can be used for inter-module messages allowing FPGA registers to be read and written to control the operation of the module as defined in the FPGA design

The PowerPC program can be downloaded as part of the FPGA design, or after the FPGA configuration using the GNU debugger (via the JTAG cable) or the HERON-FIFOs, or can be loaded from the FLASH memory provided on the module.
