14   The Xilinx platforms include a pair of Cortex-R5F processors (RPU) for
15   real-time processing based on the Cortex-R5F processor core from ARM.
16   The Cortex-R5F processor implements the Arm v7-R architecture and includes a
17   floating-point unit that implements the Arm VFPv3 instruction set.
