This paper presents the evaluation of the memory subsystem of the Xilinx Ultrascale+ MPSoC. The characteristics of various memories in the system are evaluated using carefully instrumented micro-benchmarks. The impact of micro-architectural features like caches, prefetchers and cache coherency are measured and discussed. The impact of multi-core contention on shared memory resources is evaluated. Finally, proposals are made for the design of mixed-criticality real-time applications on this platform.
