(1) The benchmark application was built using BIOS.LibType_Custom with the following compiler options:
"-mcpu=cortex-a15 -mfpu=neon -mfloat-abi=hard -mabi=aapcs -O3 -Wunused -Wunknown-pragmas -ffunction-sections -fdata-sections -Dti_sysbios_Build_useHwiMacros -Dfar= -D__DYNAMIC_REENT__".
Timings were obtained using the sdp5430 evaluation board.
The A15 core was running at 800MHz, with L1 & L2 caches enabled, and all code & data placed in External RAM starting at 0x80000000.
