The benchmark application was built using BIOS.LibType_Custom with the following BIOS.customCCOpts settings: “–endian=little -mv7M4 –float_support=vfplib –abi=eabi -q -ms –opt_for_speed=2 –program_level_compile -o3”.
To minimize the effects of wait states, the performance measurements are collected at optimal CPU clock speeds on MSP432 and Tiva devices.
See the SYS/BIOS User’s Guide for more information regarding how interrupt latency is calculated.
