(1) The benchmark application was built using BIOS.LibType_Custom with the following BIOS.customCCOpts settings: "-mcpu=cortex-m3 -mthumb -mabi=aapcs -mapcs -mcpu=cortex-m3 -mthumb -mabi=aapcs -mapcs-frame -ffunction-sections -fdata-sections -O3 -combine".
Timings were obtained using the Stellaris Blizzard LM4FSXLH5BB board running at 40MHz.
(2) The M3 target also supports zero latency interrupts. See ti.sysbios.family.arm.m3.Hwi cdocs for details.
