The benchmark application was built using BIOS.LibType_Custom with the following BIOS.customCCOpts settings: “–endian=little -mv7M3 –abi=eabi -ms –opt_for_speed=2 –program_level_compile -o3”.
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.
