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”.
The C28x targets also supports zero latency interrupts. See ti.sysbios.family.c28.Hwi cdocs for details.
See the SYS/BIOS User’s Guide for more information regarding how interrupt latency is calculated.
