Gold Code Generator

Hi,

I am a student looking for help with creating a gold codes on my nios 2 evaluation kit. I want to set it up so that it generates 8 codes simultaneously, but have very little experience with quartus or FPGA's so have not been very successful. I would really appreciate some advice.

Thanks

    Gold Codes are efficiently generated using Linear Feedback Shift Registers (LFSR) which generated pseudo-random sequences. Some time ago I have found lots of free literature about this topic on the web, I suggest you to try a search.

    After you have found the proper LFSR arhcitecture, you may implement it by using a Verilog or VHDL implementation of the LFSR and the job is done.
