32位数据转8位数据和8位数据转32位数据

1。32位数据转换为8位数据 UINT32 m_num32[512];//32里面有参数 UINT8 m_num8[2048]; UINT8 m_temp; memset(m_num8,2048); for(int i = 0; i < 512; i++) { m_temp = m_num32[i] >> 24; m_num8[i] = m_temp; m_temp = m_num32[i] >> 16; m_num8[i + 512] = m_temp; m_temp = m_num32[i] >> 8; m_num8[i + 1024] = m_temp; m_temp = m_num32[i]; m_num8[i + 1536] = m_temp; }
2.8位数据转换位32位数据 UINT32 m_num32[512]; UINT8 m_num8[2048];//8里面有数据 UINT8 m_temp; memset(m_num32,512); for(int i = 0; i < 512; i++) { m_temp = m_num8[i]; m_num32[i] |= m_temp << 24; m_temp = m_num8[i + 512]; m_num32[i] |= m_temp << 16; m_temp = m_num8[i + 1024]; m_num32[i] |= m_temp << 8; m_temp = m_num8[i + 1536]; m_num32[i] |= m_temp; }
