基于Xilinx的分频器设计

说明：  SimpleVOut (SVO) is a simple set of FPGA cores for creating video signals in various formats. The cores connect using AXI-streams. Most configurations (resolution, framerate, colordepth, etc.) are set at compile-time using Verilog parameters. See svo_defines.vh for details on those parameters.
