    DMA transactions in FX3LP

    nik.nj70_2746846

      Hello guys, I am new to Cypress FX3LP firmware making.

      I am basically developing a memory controller which uses Cypress FX3LP board to act as bridge between design and the host

      In the firmware, I have call_dmaMscOutBuffer16 and then call_dmaMscOutBuffer512

       

      My question is, while these DMAs are executed, how much time does each DMA take? and also how much time is consumed in switching from 1st DMA call to 2nd DMA call? is that time configurable? I am targetting high speed data transfer.

       

      Kindly suggest some solution.

      Also, can we determine how much time is spent in between DMA callbacks? Is there any way to reduce those callbacks?
