Arm Cortex-R series is intended to very hard real-time, and do branch prediction only if explicitly enabled > However, the Cortex-R7 and Cortex-R8 do not enable branch prediction automatically at reset. This means software must enable branch prediction to get the maximum hardware performance. https://community.arm.com/arm-community-blogs/b/architectures-and-processors-blog/posts/measuring-the-impact-of-branch-prediction-for-cortex-r7-and-cortex-r8 https://community.arm.com/arm-community-blogs/b/architecture... Its still OoO but idk how much that impacts anything Edit: apparently only r7/8 were ooo, r52/82 are in-order again
