Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.
Fig. 1 is a flowchart illustrating a file transfer method according to an exemplary embodiment, where the file transfer method is used in a first terminal, which may be a mobile phone, a tablet computer, an electronic reader, a personal digital assistant (personal digital assistant, PDA), a vehicle-mounted device, a wearable device, etc., and is connected to a second terminal, such as a Personal Computer (PC), an OTG device, or other intelligent home appliance, through a universal serial bus (Universal Serial Bus, USB) interface for performing a file-related operation. The file-related operations may be, for example, operations to list folders, download files, upload files, query file attributes, delete files, and the like.
For convenience of description, in the following description of the present disclosure, the first terminal is taken as a mobile terminal, and the second terminal is taken as a PC as an example. When the mobile terminal is connected with the PC through the USB interface, the media transmission protocol (Media Transfer Protocol, MTP) protocol is used for transmitting data with the computer so as to realize file transmission.
As shown in fig. 1, the file transfer method includes the following steps.
In step S101, an operation to increase the file transfer speed is asynchronously triggered based on the received file transfer job request information of the second terminal.
The user initiates file transfer task request information at the PC, for example, uploads or downloads a file to the mobile terminal, and communicates with the mobile terminal through USB. The MTP protocol specifies all information of the USB device, such as file reading mode, transmission mode, application program interface naming mode, etc., when the mobile terminal and the PC communicate through the USB based on MTP transmission. In file-related operations, only the contents specified in the MTP protocol need be invoked through the application program interface. When the terminal receives the file transmission task request information, the hardware triggers the interrupt, and the file transmission task is processed by the USB drive and the MTP drive of the kernel space of the mobile terminal. The MtpServer thread of the mobile terminal user space polls/dev/MTP nodes until readable, and reads the file transfer task Request content of the MTP Request.
The MtpServer thread inquires metadata of a file system from a system service MediaProvider through MtpDatabase, finds an actual file of the file system according to the metadata, reads the actual file, writes back the actual file into a USB layer and transmits the actual file to a kernel space MTP driver/dev/MTP of the mobile terminal. And the PC receives the corresponding file data and displays the file data to a user according to logic.
The mobile terminal triggers an operation of increasing a file transfer speed (boost) in order to increase the file transfer speed based on the received file transfer task request information. The boost operation is called in the file transmission MtpServer thread, the call between threads is time-consuming operation, the MTP transmission speed is reduced, and the improvement of the file transmission speed is not facilitated. And asynchronously triggering the operation of improving the file transmission speed, avoiding the influence of boost on the main thread of the MtpServer file transmission, and further improving the file transmission speed in the file transmission process.
In step S102, file transfer is performed with the second terminal based on the operation and the file transfer task request information.
And carrying out file transmission based on the operation of improving the file transmission speed and the file transmission task request information.
According to the embodiment of the disclosure, the first terminal asynchronously triggers the operation of improving the file transmission speed based on the received file transmission task request information of the second terminal, and the second terminal performs file transmission based on the improved file transmission speed and the file transmission task request information, so that the speed of the first terminal performing file transmission with the second terminal through USB is effectively improved, and the efficiency of file transmission is improved.
In one embodiment of the present disclosure, the operation of increasing the file transfer speed includes at least one of increasing an operating frequency of a central processor of the first terminal, increasing an operating frequency of a memory of the first terminal, and executing a file transfer task on a large core of the central processor.
During file transmission, a certain load is applied to the central processor of the first terminal, the memory of the first terminal and the system bus, so that the working frequency of the central processor of the first terminal can be increased, and the working frequency of the memory of the first terminal can be increased for the purpose of improving the file transmission speed.
When a Central Processing Unit (CPU) of the mobile terminal is multi-core, namely the CPU comprises a plurality of cores, the cores comprise a plurality of large cores and a plurality of small cores, the running performance of the large cores is high, and the running performance of the small cores is low. The file transfer task is executed on the big core of the central processing unit, so that the speed of the file transfer task can be increased.
Fig. 2 is a flowchart illustrating a file transfer method according to still another exemplary embodiment of the present disclosure. As shown in fig. 2, the operation of asynchronously triggering to increase the file transfer speed includes:
in step S201, upon receiving the file transfer task request information, a file transfer thread is started, and an asynchronous thread is created.
Based on MTP transmission between the mobile terminal and the PC, when receiving file transmission task request information, starting a file transmission thread MtpServer thread, and when the MtpServer thread is started to realize asynchronous triggering of boost, creating an asynchronous thread to realize boost in the asynchronous thread.
Asynchronous threads, for example, may be loop (Looper) threads, or other threads that may asynchronously trigger boost. The Looper thread is a cyclic thread, and once a new task exists, the execution is finished and the next task is waited. When the asynchronous thread is a Looper thread and the MtpServer thread receives a file transmission request, the MtpServer thread sends a request for starting a boost to the Looper thread except for executing a file transmission task, and the asynchronous triggering of the boost is realized in the Looper thread. The Looper thread alternately inquires that a file transmission task request exists in the message queue, and when a new file transmission task request exists, the file transmission task is executed, and the executed file transmission task continues to wait for the new file transmission task.
In step S202, an operation to increase the file transfer speed is invoked in the asynchronous thread.
When the file transmission MtpServer thread receives the file transmission task request, a boost request is sent to the asynchronous thread to asynchronously trigger the boost, namely, the operation of improving the file transmission speed is called in the asynchronous thread, so that the time loss of the boost to the file transmission MtpServer thread is reduced, and the effective improvement of the file transmission speed is ensured.
Taking an asynchronous thread as a Looper thread as an example, when the Looper thread receives a boost request sent by the MtpServer thread. In the Looper thread, the perfect is called to the PerfService thread by the Binder, and the PerfService thread is a service for actively regulating the system capacity in the user space of the mobile terminal, namely, the frequencies of devices of the mobile phone are increased by calling the PerfService thread in the Looper thread, so that the file transmission speed is improved.
In one embodiment, increasing the operating frequency of the memory of the first terminal includes: closing an automatic frequency reduction function of a storage space of the first terminal and/or improving the transmission bandwidth of a memory of the first terminal system.
The method comprises the steps that the working frequency of a memory of the mobile terminal is improved, the automatic frequency reducing function of an embedded multimedia memory (Embedded Multi Media Card, eMMC) or a universal flash memory (Universal Flash Storage, UFS) of a storage space of the mobile terminal is closed, the eMMC is a nonvolatile memory, data can be stored no matter in an electrified state or an outage state, the method is mainly used for storing the data in the mobile terminal, so that the frequency of a memory can not be reduced along with the progress of a transmission task in the process of file transmission of the mobile terminal through USB, the working frequency of the memory of the mobile terminal is ensured, and the file transmission speed is improved.
Increasing the operating frequency of the memory of the mobile terminal further includes increasing the bandwidth of a system memory, such as a Double Data Rate (DDR), to enable the system of the mobile terminal to achieve a higher Data transmission operating frequency.
Fig. 3 is a flowchart illustrating a file transfer method according to still another exemplary embodiment of the present disclosure. As shown in fig. 3, the file transfer method includes the following steps.
In step S301, an operation to increase the file transfer speed is asynchronously triggered based on the received file transfer job request information of the second terminal.
In step S302, file transfer is performed with the second terminal based on the operation and the file transfer task request information.
In step S303, after the completion of the file transfer, it is determined to perform an operation of canceling the increase in the file transfer speed.
When the mobile terminal is in the process of file transmission, the MtpServer thread receives file transmission task request information, the MtpServer thread is started, and a request for starting Boost is sent to an asynchronous thread, so that the Boost is triggered asynchronously. When the mobile terminal performs boost, the working frequency of devices such as a mobile terminal CPU and a memory is continuously improved, and when the time for file transmission is long, the mobile terminal device is high in frequency, so that the mobile phone is heated seriously, and bad user experience is brought. At the MtpServer thread polling/dev/mtp node, no new file transmission request is queried, and transmission is stopped, at this time, the MtpServer sends a request for canceling Boost to cancel Boost, so that the frequency during the mobile terminal is reduced to be the normal working frequency, and the influence of temperature rise on the service life of mobile terminal devices is avoided.
Based on one inventive concept, the present disclosure also provides a display device of a terminal interface theme.
