13 The TI K3 family of SoCs usually have one or more dual-core Arm Cortex R5F
14 processor subsystems/clusters (R5FSS). The dual core cluster can be used
15 either in a LockStep mode providing safety/fault tolerance features or in a
16 Split mode providing two individual compute cores for doubling the compute
20 AM64x SoCs do not support LockStep mode, but rather a new non-safety mode

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.
