檢視作業系統是 32 位還是 64 位

dpkg --print-architecture
           

檢視記憶體狀态

sudo ./tegrastats

RAM – 記憶體占用
cpu – 當然就是CPU占用率了，TX2一共6個核
EMC – external memory controller, 外存控制器 機關 bus%@MHz
AVP – audio/video processor, TX2 自帶的音頻視訊ASIC處理器 機關 processor%@MHz
VDE – video decoder engine, TX2 帶有視訊編解碼hevc的加速器 %MHz
GR3D – GPU, processor， GPU的主頻 %@MHz
