Xilinx’s Zynq UltraScale+ MPSoC Diagrams are Wrong

find_all_the_bugs_1

This post presents a bug in the Zynq UltraScale+ MPSoC diagrams at xilinx.com.

All of the diagrams on the Zynq UltraScale+ MPSoC Product Landing Page share a common problem.

Here’s the Application Processing Unit excerpt from a larger block diagram at link:

application_processing_unit_excerpt_2

Look at where they put the ARM Cortex-A53 text:

arm_cortex_a53_location_3

Are there 4 ARM Cortex-A53’s? There are not. There is _one_ Cortex-A53 with four cores that contain one Armv8-A CPU each.

Arm documents the Cortex-A53 more accurately at the Cortex-A53 site:

cortex_a53_accurate_documentation_4

So the diagram from Xilinx should look like:

corrected_xilinx_diagram_5

Xilinx makes the same mistake with the R cores as well.
