Can't this be done on the Metlino (where it *might* make more sense to have a MPSoC) or with gateware?

There is no shortage of general purpose FPGA boards for Zynq users. Do we really want to compete in this market? Sébastien ___ ARTIQ mailing list https://ssl.serverraum.org/lists/listinfo/artiq

On the DSP/"Sayma" boards, a hard SoC could have use for reducing the time it takes to perform feedback calculations (e.g. shifts of output signal frequency based on ADC readings). My comment in the previous email about "users" wanting this also pertains to the idea that people not using ARTIQ might want to buy these boards and use them for their own purposes. For many of them, having a hard SoC on board may make it faster/easier for them to get the boards doing what they want.
