The Video Processing Subsystem uses three clocks that are derived through a clock generator from the 200 MHz system clock that is available on the AMD Kintex™ 7 KC705 board. The memory subsystem is running at this system clock at 200 MHz. This system clock feeds into the clock wizard IP, which derives a 300 MHz and 100 MHz clock at the output. The 300 MHz clock drives the AXI4-Stream video interfaces. The 100 MHz clock drives the AXI4-Lite control interface, and also drives the processor.
