(1) 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".
Timings were obtained using the Tiva Launchpad TM4C123GH6PM board running at 40MHz.
(2) The M3 target also supports zero latency interrupts. See ti.sysbios.family.arm.m3.Hwi cdocs for details.
