(1) The benchmark application was built using BIOS.LibType_Custom with the following compiler options: "--neon --endian=little -mv7A8 --abi=eabi -ms --embed_inline_assembly --opt_for_speed=2 --program_level_compile -o3 -g --optimize_with_debug".
Timings were obtained using the evmDM8168 development board.
The A8 core was running at 987MHz, with L1 & L2 caches enabled, and all code & data placed in OCMC0.
Unlike other target benchmarks that are collected using flat memory simulators or hardware with zero wait-state memory and no cache, these A8F numbers are collected on a real board with cache enabled and no-attempt to pre-fill the cache. These numbers are effected by varying amounts of cache filling depending on the dynamics of the cache and the previous function calls.
