摘要： Embodiments of the present invention disclose an ATCA data exchange system, an exchange board and a data exchange method. The ATCA data exchange system includes: a backboard, at least one exchange board and at least one service board. The exchange board includes at least one Fabric port group, and each Fabric port group is connected to a service board through the backboard to form a first exchange channel for broadband service data exchange, where the Fabric port group includes four difference sending and receiving port pairs, and each difference sending and receiving port pair includes a pair of difference receiving ports and a pair of difference sending ports. A connector 20 in the Fabric interface of the exchange board includes at least one difference sending and receiving port pair, and each difference sending and receiving port pair is connected to a service board through the backboard to form a second exchange channel that is independent of the first exchange channel, for narrowband service data exchange that is independent of the broadband data exchange through the second exchange channel separately. Through the embodiments of the present invention, processing of narrowband data is simplified, and time delay is decreased.

摘要： A device suspend method and a computing device are provided. In the method, before a device enters a suspend state, memory space occupied by a background process that is unrelated to a foreground process is released. In this way, the background process that is unrelated to the foreground process is not saved in a memory of the device. In other words, data stored in the memory when the device is suspended is reduced. Therefore, when the device needs to be woken up, only a relatively small amount of data needs to be read from the memory, and a working state can be rapidly restored. This can reduce a delay of reading data from the memory when the device is woken up, thereby accelerating a wakeup speed of the device. In addition, the data is stored in the memory when the device is suspended. Therefore, in the suspend state, power needs to be supplied only to the memory of the device, thereby ensuring low power consumption of the device.
