The benchmark application was built using BIOS.LibType_Custom with the following compiler options:
“-mcpu=cortex-a15 -mfpu=neon -mfloat-abi=hard -mabi=aapcs -O3 -Wunused -Wunknown-pragmas -ffunction-sections -fdata-sections -Dti_sysbios_Build_useHwiMacros -Dfar= -D__DYNAMIC_REENT__”.
See the SYS/BIOS User’s Guide for more information regarding how interrupt latency is calculated.
