(1) The benchmark application was built using BIOS.LibType_Custom with the following BIOS.customCCOpts settings: "-me -mv5e --abi=eabi -ms --opt_for_speed=2 --program_level_compile -o3".

Timings were obtained using the OMAP-L138

The Timestamp Provider used for this test runs at 24Mhz with the core at 300Mhz. Figures could be off by +- 12.5 cycles.
