FFT compute resource used - Software in ARM processor only, NEON SIMD, or PL Accelerated (See yellow status window for average compute time)
Compute Type - Normal / Multiple - multiple reads and computes 1000 FFTs and then displays the last computed value. This is useful for seeing relative update performance and CPU loading.
Status Window - displays average compute time for the FFT - depends on FFT Type selected.
Performance - shows the CPU loading and use of the HP ports bewteen the PS and PL.
Block Diagram shows the data flow in the application - changes based on selected input and FFT Type.
Usage - graphically shows CPU and AXI bus loading
This demonstration clearly shows the power of the Zynq 7000 AP Soc in action. Observers can see the FFT being performed and displayed and compare the different methods of performing the complex FFT calculations. The graphics are performed with the Qt system in conjunction with the hardware display controller used in the video base Targeted Reference Design, demonstrating the power of the Vivado / SDK development environment and compatibility with standard ARM / Linux system components that users might access in building their Zynq based systems.
