(1) The benchmark application was built using BIOS.LibType_Custom with the following BIOS.customCCOpts settings: "-v28 -DLARGE_MODEL=1 -ml -mo --program_level_compile -o3".
Timings were obtained using the ezdsp28335 development board.
(2) The C28x targets also supports zero latency interrupts. See ti.sysbios.family.c28.Hwi cdocs for details.
