When the compressed files are used, they need to be decompressed online so that they can be correctly read and used by the application.
[0003] In the related art, decompression is achieved through software services. The performance of software decompression is limited by the processor capability, and software decompression will increase the power consumption and utilization of the processor.
[0004] Therefore, how to reduce the utilization rate of the processor during the decompression process is one of the problems that those skilled in the art need to solve urgently. Summary of the invention
[0005] The embodiment of the present application provides an online decompression device and method for reducing the utilization rate of the processor during the decompression process. To achieve the above purpose, the embodiment of the present application adopts the following technical solutions:

The file control module is also used to send a first message to the decompression module. The decompression module is used to decompress the data blocks to be decompressed in the first decompression queue to the internal memory according to the first information. The decompression module is also used to send a second message to the file control module.

[0007] In the related art, decompression needs to be performed by software on the processor, that is, the processor must participate in the entire decompression process. In the solution provided by the embodiment of the present application, the processor only needs to send a decompression request to the file control module of the online decompression device, and the subsequent decompression process is performed by the online decompression device, thereby reducing the utilization rate of the processor during the decompression process.

[0014] It can be seen that in the solution provided in the embodiment of the present application, the file control module of the online decompression device can divide the file to be decompressed into multiple data blocks to be decompressed, so there is no need to decompress the entire file at one time, thereby improving the decompression performance.
[0015] In a possible implementation, the above N is an integer greater than 1.
[0016] It can be understood that, if N is an integer greater than 1, it means that there are multiple decompression queues, and the multiple decompression queues can perform decompression operations simultaneously, thereby improving the decompression performance and reducing the decompression time.

[0020] It can be seen that in the solution provided in the embodiment of the present application, the communication between the modules between the online decompression devices can be realized through the collaborative module. Compared with realizing the communication between the modules between the online decompression devices through the processor, realizing the communication between the modules between the online decompression devices through the collaborative module can further reduce the utilization rate of the processor during the decompression process.

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the embodiments of the present application.
[0042] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.
[0045] It should be noted that in the description of the embodiments of the present application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplarily" or "for example" in the embodiments of the present application should not be interpreted as having priority or advantage over other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a specific way.
[0046] Due to the limited storage space, files need to be compressed, especially for files that are not frequently used and occupy a large amount of space, which need to be stored after compression to save the limited external storage space of electronic devices. When the compressed files are used, they need to be decompressed online so that they can be correctly read and used by the application.
[0047] To this end, the embodiment of the present application provides an online decompression device 100 for reducing the utilization rate of the processor during the decompression process. Figure 1 As shown, the online decompression device 100 includes a file control module 101 and a decompression module 102 .
[0048] The file control module 101 is used to receive a decompression request from a processor, where the decompression request is used to instruct decompression of the file to be decompressed.
[0049] The file control module 101 is further configured to move the data blocks to be decompressed in the external memory to N decompression queues according to the decompression request, wherein the data blocks to be decompressed are data blocks of the file to be decompressed.
[0050] The file control module 101 is further used to send first information to the decompression module, where the first information is used to instruct to perform a decompression operation on the to-be-decompressed data blocks in the first decompression queue, where the first decompression queue is any one of the N decompression queues.
[0051] The decompression module 102 is used to decompress the to-be-decompressed data blocks in the first decompression queue into an internal memory according to the first information.
[0052] The decompression module 102 is further used to send second information to the file control module, where the second information is used to indicate that the data blocks to be decompressed in the first decompression queue have been decompressed into the internal memory.
[0053] In the related art, decompression needs to be performed by software on the processor, that is, the processor must participate in the entire decompression process. In the solution provided by the embodiment of the present application, the processor only needs to send a decompression request to the file control module of the online decompression device, and the subsequent decompression process is performed by the online decompression device, thereby reducing the utilization rate of the processor during the decompression process.
[0054] In a possible implementation, the file control module 101 is further used to: send third information to the decompression module, wherein the third information is used to indicate that a decompression operation is performed on the data block to be decompressed in the first decompression queue and that the data block to be decompressed in the first decompression queue is the last data block of the file to be decompressed.
[0055] In a possible implementation, the file control module 101 is further used to: send fourth information to the processor, where the fourth information is used to indicate that the file to be decompressed has been decompressed.
[0056] In a possible implementation, the file control module 101 is further configured to generate a plurality of data blocks to be decompressed according to the file to be decompressed.
[0057] Exemplarily, the file control module 101 may divide the to-be-decompressed file into a plurality of to-be-decompressed data blocks according to a preset compression granularity, wherein the preset division granularity may be 4KB, 16KB, 64KB, 1MB or others.
[0058] It can be understood that during the decompression process, through the collaboration of software and hardware, the application running on the processor does not need to be blocked waiting for the decompression to be completed, thereby achieving concurrency between the decompression and the application.
[0059] Exemplarily, the decompression queue may be a circular buffer.
[0060] It is understandable that if the file to be decompressed needs to be fully or partially loaded into the memory, and then the decompression module is notified to decompress it, it is impossible to effectively work in parallel between file loading and decompression. The file decompression data adopts a circular buffer method to achieve concurrent decompression, data loading, data use, etc., and realize online real-time use.
[0061] Exemplarily, the decompression module 102 may be a data compression unit (DCU).
[0062] In a possible implementation, the above N is an integer greater than 1.
[0063] It can be understood that, if N is an integer greater than 1, it means that there are multiple decompression queues, and the multiple decompression queues can perform decompression operations simultaneously, thereby improving the decompression performance and reducing the decompression time.
[0064] In the related art, decompression needs to be performed by software on the processor, that is, the processor must participate in the entire decompression process. In the solution provided by the embodiment of the present application, the processor only needs to send a decompression request to the file control module of the online decompression device, and the subsequent decompression process is performed by the online decompression device, thereby reducing the utilization rate of the processor during the decompression process.
[0065] Compared with executing file decompression through software on the processor, executing file decompression through a hardened decompression module can achieve processor load offloading and improve processor computing energy efficiency.
[0066] like Figure 2 As shown, the online decompression device 100 may further include a coordination module 103 .
[0067] The above-mentioned cooperation module 103 is used to receive the above-mentioned first information from the file control module.
[0068] The above-mentioned cooperation module 103 is further used to send the above-mentioned fifth information to the above-mentioned decompression module, and the above-mentioned fifth information is used to instruct to perform a decompression operation on the to-be-decompressed data blocks in the first decompression queue.
[0069] The above-mentioned cooperation module 103 is also used to receive the above-mentioned second information from the decompression module.
[0070] The above-mentioned collaboration module 103 is also used to send the above-mentioned sixth information to the above-mentioned file control module, and the above-mentioned sixth information is used to indicate that the data blocks to be decompressed in the above-mentioned first decompression queue have been decompressed to the internal memory.
[0071] The above-mentioned collaborative module 103 is also used to receive third information from the file control module, and the above-mentioned third information is used to indicate that a decompression operation is performed on the data block to be decompressed in the above-mentioned first decompression queue and the data block to be decompressed in the above-mentioned first decompression queue is the last data block of the file to be decompressed.
[0072] The above-mentioned collaborative module 103 is also used to send the above-mentioned seventh information to the above-mentioned decompression module, and the above-mentioned seventh information is used to indicate that a decompression operation is performed on the data block to be decompressed in the above-mentioned first decompression queue and the data block to be decompressed in the above-mentioned first decompression queue is the last data block of the file to be decompressed.
[0073] Exemplarily, the above-mentioned collaboration module 103 may be a heterogeneous taskschedule (HTS).
[0074] It is understandable that the coordinated control functions between file loading and decompression require the processor to complete the control scheduling, and the processor cannot be put into sleep mode, which results in high energy consumption. The hardened file control module supports the control of loading files to be decompressed, driving decompression, and data movement, which can reduce the overhead of processor computing resources.
[0075] like Figure 3 As shown, the N decompression queues may be arranged in the online decompression device 100 .
[0076] In a possible implementation, the N decompression queues may also be set in the internal memory.
[0077] The present application also provides an electronic device, such as Figure 4 As shown, the electronic device 400 includes an online decompression device 100 , a processor 401 , an internal memory 402 and an external memory 403 .
[0078] Exemplarily, the electronic device in the embodiments of the present application may be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, a vehicle-mounted device, an ultra-mobile personal computer (UMPC), a netbook, and a cellular phone, etc. The embodiments of the present application do not impose any special restrictions on the specific form of the device.
[0079] Exemplarily, the processor 401 may be a central processing unit (CPU), a graphics processing unit (GPU), a general-purpose processor network processor (NP), a digital signal processor (DSP), a microprocessor, a microcontroller, a programmable logic device (PLD), or any combination thereof. The processor 401 may also be other devices with processing functions, such as circuits, devices, or software modules, without limitation.
[0080] Exemplarily, the internal memory 402 may be a random access memory (RAM). By way of example and not limitation, many forms of RAM are available, such as static RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), synchronous link DRAM (SLDRAM), and direct RAM bus RAM (DRRAM).
[0081] Exemplarily, the external memory 403 may be a universal flash storage (UFS), an embedded multi media card (EMMC), a solid state drive (SSD), a hard disk drive (HDD), or other external memory.
[0082] Figure 5 An online decompression method provided by an embodiment of the present application is shown, and the method includes:
[0083] S501: The processor sends a decompression request to the file control module.
[0084] Accordingly, the file control module receives a decompression request from the processor.
[0085] The decompression request is used to instruct decompression of the file to be decompressed.
[0086] Exemplarily, the above-mentioned file to be decompressed can be a compressed file in 7z, Rochelle archive (RAR), zip or other formats, which is not limited in this embodiment of the present application.
[0087] Exemplarily, the user application (application, APP) running in the processor can specify the online decompression file according to the scenario and specify the target memory address after decompression, as well as call the corresponding software interface and specify the parameter implementation (such as the parameters can include decompression Decompress, file name Filename, path DecAddr). The file system module of the operating system running in the processor, after receiving the file name and path to be decompressed sent by the APP, performs a parsing query to determine the block address of the file in the external memory, and further converts it into a call command for block input output (Block IO) reading, and sends it to the file control module through the driver module of the external memory.

[0097] S504: The decompression module decompresses the to-be-decompressed data blocks in the first decompression queue into the internal memory according to the first information.
[0098] Exemplarily, the decompression module may decompress the to-be-decompressed data blocks in the first decompression queue according to the first information, and after the decompression is completed, the decompressed data blocks may be moved to the internal memory according to the target memory address.
[0099] In a possible implementation, the decompression module may also decompress the to-be-decompressed data blocks in the first decompression queue into the internal memory according to the first information, that is, the decompressed data may be stored in the internal system cache or the internal memory.
[0100] S505: The decompression module sends second information to the file control module.
[0101] Correspondingly, the file control module receives the second information from the decompression module.
[0102] The second information is used to indicate that the data blocks to be decompressed in the first decompression queue have been decompressed into the internal memory.
[0103] Exemplarily, the decompression module may send second information to the file control module to notify the file control module that the to-be-decompressed data block may continue to be loaded.
[0104] Exemplarily, the second information may be an E7 event, and the rule corresponding to the E7 event may be “notify the decompression queue No. x that the data has been decompressed and that the decompression can continue.”
[0105] It can be understood that the above steps are repeated until the file to be decompressed is completely decompressed.
[0106] In a possible implementation, the file control module may also send third information to the decompression module, wherein the third information is used to indicate that a decompression operation is performed on the data block to be decompressed in the first decompression queue and that the data block to be decompressed in the first decompression queue is the last data block of the file to be decompressed.
[0107] Exemplarily, the third information may be an E2 event, and the rule corresponding to the E2 event may be "the last block of data to be decompressed is loaded into the decompression queue No. x, decompression can be started, and there is no subsequent data."
[0108] In a possible implementation, the file control module may further send fourth information to the processor, where the fourth information is used to indicate that the file to be decompressed has been decompressed.

[0119] Accordingly, the decompression module receives the fifth information from the cooperation module.
