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 1.6M

* 计算耗时 cpu 37%

  * ./test_aec_anr_agc csq_0_1mic.wav csq_0_1mic-out.wav
    filename=csq_0_1mic.wav format=1 num_channels=2 sample_rate=16000 sample_bits=16 num_samples=128001
    mic_channel = 1, ref channel = 1
    init ch 0
    init ch 0 succeed
    init ok
    alloc ok

* 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
