Does FPGA-TO-HPS SDRAM in Cyclone V and other supported FPGASOC access SDRAM physical memory directly ?

Hi

I was wondering if the address issued by the FPGA IP on the FPGA-TO-HPS SDRAM is the physical address of the SDRAM or he virtual address ?

Can you refer to any of Intel manuals describing this information as I cannot find a definite answer in manuals?

Thanks. alot

    Hello Rana,

    I assume you are referring to F2SDRAM bridge right?

    If yes, then, the memory address here is physical. Virtual address is created and accessed via operating system (like Linux). From FPGA point of view, everything is physical.
