The benchmark application was built using BIOS.LibType_Custom with the following compiler options: “–endian=little -mv7A8 –abi=eabi –neon –float_support=vfpv3 -q -ms –opt_for_speed=2 –program_level_compile -o3”.

Timings were obtained with the cache enabled.

See the SYS/BIOS User’s Guide for more information regarding how interrupt latency is calculated.
