Hello, I am looking for the DMA driver and epics device support module for the Xilinx Zynq and Zynq ultrascal+ core. Does anyone have to experience generic DMA support for the Xilinx Zynq or Zynq ultrascal+ core or have a plan for the development? For example, we developed four channel 500 MHz digitizer for the bunch by bunch beam position monitor (performance looks good, < 300 nm turn by tune position for the NSLS-II).
Currently, prototype supports an FPGA logic block ram (BRAM, 8 K/16 K * 16bit * 4, 500MHz clock rate) .
I have plan provides at least 1 M * 16bit * 4) or 2 M points from the external DDR3/4 memory (FPGA side we implemented DMA core, but Linux part needs help) .
Because our physics group wants to minimum 1000 turns BxB position data. If we have an epics device support, that’s very valuable for many diagnostics applications, especially beam diagnostics and physics applications. Thanks, Kiman |
