The benchmark application was built using BIOS.LibType_Custom with the following BIOS.customCCOpts settings: “-mv6740 -mi10 -mo -pdr -pden -pds=238 -pds=880 -pds1110 –program_level_compile -o3”.
As the timer used to run these benchmarks is run at 1/25 the CPU frequency, a deviation of +-25 cycles is to be expected.
See the SYS/BIOS User’s Guide for more information regarding how interrupt latency is calculated.
