So… I was wondering why dCS would use such a high-capacity FPGA on the Lina; made sense when I looked properly at the Lina DAC Circuit boards;
Unlike the rest of the dCS families, Lina doesn’t have a separate Control board with FPGAs, so it would appear this one big FPGA is actually doing all DSP duties, though now in conjunction with an XMOS chip; input processing, filters, mapper, etc. etc.
All of which suggests Lina has quite a different evolutionary firmware stream from the rest of the dCS families.
Interesting times
