UFO Operation

Timeouts

  • The DMA timeout is at least 50ms
  • The bellow is explained how long it takes to read frame by hardware. We also need to add DMA timeout + PCIe transfer time on top of that before we can expect to acquire frame
    Full readout time = exposure time + fot + readout time
    FOT = (reg73 + 2*(16/number_outputs))*129*clk_per
    
    Readout time = (129 * clk_per * 16/number_outputs) * num_lines,
    
    where:
    
    reg73= 7 (I think, just check this)
    number_outputs = 16 -for 10bit, 4 - for 12bit
    clk_per=25ns
    num_lines = 1088 or 2047 or 1, depends what you set....
