(1) The benchmark application was built using BIOS.LibType_Custom with the following BIOS.customCCOpts settings: "--endian=little -mv7M3 --abi=eabi -ms --embed_inline_assembly --opt_for_speed=2 --program_level_compile -o3".
Timings were obtained using the Stellaris evmLM3S8962 board running at 80MHz.
(2) The M3 target also supports zero latency interrupts. See ti.sysbios.family.arm.m3.Hwi cdocs for details.
