Cortexa53 AARCH64 context switch

I have been trying to do a preemptive context switch on interrupt on the Cortexa53 but it isn't working can anyone spot an error in the code. The code has no FPU use so it is supposed to be just a lazy...

Optimization of Neon Intrinsics on ARM cortexa53

I am using ARMv8 GCC compiler and I would like to optimize Neon Intrinsics code for better execution time performance. I have already tried loop unrolling and I am using look up table for the computation...

How can I confirm how fast the Cortex-A57 and CortexA53 cores are being clocked at on my Juno board?

I'm using the standard firmware with an OpenEmbedded filesystem on a Juno Development Platform
