Hi All,
Now, I try to play wav file with libopenal and libault in a project on omap3530.So, I porting openal and alut librarys to omap3530.
I wrote a demo to play wav based on libopenal and libault, However, I found that the demo takes up about 30% cpu! In contrast,
the aplay just takes up 5%-6% cpu.
I'm using GCC 4.3.3 (CodeSourcery 2009q1). These are my current compiler flags:"CFLAGS = -O2"
and I also try "CFLAGS = -s -save-temps -Wall -O3 -march=armv7-a -mtune=cortex-a8 -mcpu=cortex-a8 -mfloat-abi=softfp
-mfpu=neon -ftree-vectorize -fomit-frame-pointer -ffast-math", the problem is still.
Can anyone tell me, what happened? If my porting has problems? please forgive my poor English,
Thanks in advance for any assistance.
