Rockchip HDAEC算法

compile

mkdir -p build cd build cmake .. -DCMAKE_TOOLCHAIN_FILE=~/video/rv1109/buildroot/output/rockchip_puma_toolchain/host/share/buildroot/toolchainfile.cmake make

优化选项： -O3 -mfpu=neon -mfloat-abi=hard

资源占用情况

测试环境

• RV1808 EVB

• cpu: 关闭ARM核保留一个核，定频 1Ghz

  echo userspace > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

  echo 1008000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed

  echo 0 > /sys/devices/system/cpu/cpu1/online

• ddr : LPDDR3 933MHz

Test

• 内存占用情况：RSS 1.5M

• 计算耗时 cpu 9%

  • ./test_hdaec_file txin.pcm rxin.pcm txout.pcm rxout.pcm

    elapse 4 ms //50ms数据 elapse 5 ms //50ms数据

• 稳定性测试 * 多实例循环压力测试通过：没有内存泄露，可以稳定长时运行
