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%
