Zynq fpga fabric clock speed?

Former Member

Hi,

I have seen mention of 100 Mhz in the forums.

But what would be a realistic max frequency that the zynq logic fabric could be usably clocked out on the zedboard?

Thanks

    What are you comparing against?
    The Zynq-7010 to Zynq-7020 has Artix-7 fabric, it is comparable to that.  The Zynq-7030 and above use Kintex-7 Fabric and is comparable to that.

    Are you just looking for the maximum clock rate?  You can find that in the Zynq-7000 AP SoC data sheets - again, depends on which chip you are looking at.

    Performance is a bit subjective on FPGA devices, since you can parallel the code and there is a dependence on what you are doing.  For example, "Peak DSP Performance" ranges from 100 GMACs to 2622 GMACs depending on chip selection.

    If you can tell me more about your application or what you are trying to determine as "performance" I can help guide to to your answer.
