hellow,
i want to connect FPGA with DSP(TMS320C6678) using EMIF16.But here i have a qustion.The IO stand of emif16 is LVCOMS18(0V~1.8V).I can configue the IO standard of fpga IO pins to identify this kind of IO stand in adress lins.
But in terms of data lines, my fpga(virtex4 XC4VSX25) can only output the voltage of i3.3V and 0V .It means that i can configure the fpga to identify the data that DSP transmit to fpga.But if I want to transmit data from fpga to DSP,the fpga outputs the voltage of 3.3V and 0V,which is higher than the emif inerface IO standard.I want to knwo how to solve this problem?Or can I ignore this qustion by connect them directly.
thanks,
Corbin luo
