Beegle Board Performence
Hi,
I am using beegle board for execute my code block. As you all know beegle use the TI OMAP 35XX architecture ! My issue is i am writing the code in 2 different way One is using C and another is using Neon Intrinsics and Parallise the code and I am using the following tool chain and switches for compilation CC=arm-none-linux-gnueabi-gcc CORTEX=-march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp -flax-vector-conversions Really the issue is both code working fine. But the time to execute the code almost same. But i use the same source in Other profilers there is some significan improvement in the cycle count (ie :: Time Difference) The beegle board configuration is Advanced SIMD NEON enabled and use the angstrom linux as the OS Where i failed to get a better performence .? Please answer ! The NEON intrinsics are getting at the following link :: http://gcc.gnu.org/onlinedocs/gcc/AR...ntrinsics.html Rgds Dave |
Could be how the tools you have relate to those systems. Some tools tend to be faster since they have been more well tuned to some system or set of systems.
