5-3-3 RFI_AM Board
(cont’d)
5-3-3-4 FPGA Download
The FPGAs contain no configuration upon power-ON; FGPA Download proceeds as follows:
1.) The actual FPGA contents (bit-streams) are written into DSP memory from the Host.
2.) The DSP configures serial port 0 to aid configuration.
3.) The DSP writes the bit-streams to serial port 0.
4.) The DSP verifies that the FPGAs are configured correctly.
5-3-3-5 PCI Connection
The RFI_AM Board interfaces directly to the PCI bus via the DSP PCI to the local bus bridge.
