Where can I find the source code for the FPGA board?
The NDI Advanced SDK contains the VHDL source that is available for the NDI codec cores. The low-level encode and decode functions are currently provided as an encrypted library.
To properly implement the FPGA codecs in the NDI Advanced SDK requires:
- ARM (or x86) CPU running Linux for the NDI software libraries
- Shared memory between the CPU and FPGA for communicating the compressed NDI data
- Register access to the FPGA from the CPU
- Frame buffer memory for the FPGA to store uncompressed video data (does not need to be visible to the CPU)
For these reasons the examples provided all target SoC+FPGA parts from Xilinx and Altera. Using an SoC+FPGA part is not mandatory, but anything else will require additional development effort and similar system performance (eg: a PCIe link to the FPGA could work well for transferring NDI compressed data and register I/O).
