The benchmark application was built using BIOS.LibType_Custom with the following BIOS.customCCOpts settings:
“-mcpu=cortex-m3 -mthumb -mabi=aapcs -O3 -Wunused -Wunknown-pragmas -ffunction-sections -fdata-sections -Dti_sysbios_Build_useHwiMacros -Dfar= -D__DYNAMIC_REENT__”.
The M3 target also supports zero latency interrupts. See ti.sysbios.family.arm.m3.Hwi cdocs for details.
See the SYS/BIOS User’s Guide for more information regarding how interrupt latency is calculated.
