Serial Configuration of the User FPGA
The HERON-IO5 usually has the configuration of the User FPGA downloaded using the
HERON module’s serial configuration bus. This allows the use of “standard”
configurations as supplied on the HUNT ENGINEERING CD, or of user defined
configurations without the need to return the module to the factory.
It is imagined that as the “standard” set of functions grows, that they be made available to
users of HERON-FPGA and IO modules via the HUNT ENGINEERING web site or
CD update requests. Also HUNT ENGINEERING will have the possibility to provide
semi-custom configurations for a charge via email.
Boot ROM
As an alternative to the serial configuration download, it is possible to configure the FPGA
from a Flash based configuration PROM. It is an advantage when the DSP system will be
ROM booted, as it removes the need for the DSP FLASH ROM to store the configuration
for the FPGA too. However, if a system is being deployed with a host machine such as a
PC, it might be preferable to continue to use the serial configuration method, as this will
make in field upgrades and bug fixes simpler to deploy.
The PROMS fitted to the HERON-IO5 are Flash based, and can be programmed (and reprogrammed) using a Xilinx JTAG cable (such as Xilinx parallel cable 4, or USB cable).
