Heterogeneous computing on CORTEX A53 via TrustZone


The pages 19 and 22 of https://www.xilinx.com/support/documentation/sw_manuals/ug1228-ultrafast-embedded-design-methodology-guide.pdf indicate that heterogeneous computing on the APUs (CORTEX A53) is unsupported. However pages 138/139 indicate that a Trusted Execution Environment is possible on that board. Since it is possible to run a secure OS in the TEE and that secure OS may be totally unrelated to the OS/hypervisor that runs outside the TEE, how can I have the insurance that this type of heterogeneous computing on the APUs will actually work correctly on this board. As an information, our system runs on the ARM Juno R2 board today.

Thanks in advance.
