[0002] In common embedded systems, the startup speed is often an important indicator affecting user experience. The startup methods are generally divided into cold startup and warm startup. Cold startup refers to the startup process of the product from complete power-off to power-on. Warm startup refers to the process of restarting when the product is not completely powered off but in a low-power sleep state upon receiving a user instruction. During cold startup, the device needs to read out the data files stored in the memory and use these data files to control the device startup. The time-consuming of the cold startup process mainly lies in the loading and verification processes of these data files. Common operations to improve the cold startup time-consuming include increasing the reading / loading speed, improving the device running performance, optimizing the startup process, compressing the data files to reduce the data transmission volume, etc. Among the above means, limited by the conditions of the device system itself and the rigid requirements such as process needs, data compression, as a low-cost and high-benefit solution, has become a relatively mainstream technical means to accelerate the startup speed. However, in the conventional data compression startup method, the reading and compression of data are executed serially. Summary of the Invention

[0026] Refer to Figure 1 , Figure 1 which is a schematic flowchart of the first embodiment of the method for starting up the device of the present application. This method is applied to an electronic device, and the electronic device is provided with a controller and a storage device. This method includes but is not limited to the following steps.

[0027] S11: In response to the power-on of the electronic device, the controller reads the compressed data block in the compressed data from the storage device, and the compressed data block in the compressed data is obtained by compressing the startup data of the electronic device.

[0028] When the electronic device is powered on, data reading usually starts from the default reading address of the storage device. During the upgrade process of the electronic device, the electronic device stores the compressed data obtained by compressing the startup data of the electronic device in the storage device for reading when powered on.

[0029] The startup data of the electronic device may include a read-only startup program, a startup boot program, etc. This startup data is used to control the startup of the electronic device.

[0030] The obtained compressed data includes multiple compressed data blocks.

[0031] S12: While the controller decompresses the current compressed data block, it reads the next compressed data block until all compressed data blocks are decompressed.

[0032] After the controller reads the current compressed data block, it starts to read the next compressed data block while starting to decompress the current data block.

[0033] For example, the compressed data includes several compressed data blocks A, B, C, D, etc. The electronic device first reads the compressed data block A. After reading the compressed data block A, it decompresses the compressed data block A. When starting to decompress the compressed data block A, it starts to read the next compressed data block B. After reading the compressed data block B, when starting to decompress the compressed data block B, it starts to read the next compressed data block C. Then when starting to decompress the compressed data block C, it starts to read the next compressed data block D, and so on.

[0034] S13: The controller reads and decompresses all the compressed data blocks in the compressed data to obtain the startup data, and uses the startup data to control the startup of the electronic device.

[0035] When all the compressed data blocks in the compressed data are decompressed, the startup data can be obtained, and the controller executes the startup data to control the startup of the electronic device.

[0036] In this embodiment, when the electronic device is powered on and started, it starts to read the compressed data in the storage device of the electronic device. When reading the compressed data blocks in the compressed data, the decompression and reading processes of the compressed data blocks are executed in parallel, and the next compressed data block is read while the current compressed data block is being decompressed. Through parallel processing, the acquisition speed of the startup data obtained by the controller is improved, the startup speed of the electronic device is increased, the time consumed by the user for startup is reduced, and the user experience is improved.

[0037] Under normal circumstances, during the process of decompressing and reading the compressed data blocks, affected by the reading performance of the storage device, the decompression performance of the controller, and some other related factors, there may still be a difference in the decompression time of the current compressed data block and the reading time of the next compressed data block. Even when the reading speed of the storage device and the decompression speed of the controller are similar and the data volume of each compressed data block is equal, the decompression time of each compressed data block may still vary, and there is still a difference in the time difference between the maximum decompression time and the minimum decompression time, and there may also be a certain difference from the data reading time of the compressed data block. Therefore, in order to further make full use of the transmission and decompression performance of the electronic device, the present application uses the following method to perform dynamic compression on the compressed data to obtain multiple compressed data blocks.

[0038] In some embodiments, the compressed data block is obtained by compressing the startup data based on the data reading time and the data decompression time.

[0039] During the data reading process, the data reading speed is usually stable. It is related to the hardware performance of the device. The data reading speed can be obtained through testing the storage device. For example, when reading 100 MB of data from the storage device and it takes 1 second, the data reading speed of this electronic device is 100 MB / s. Then the data reading time is correspondingly stable, that is, when reading different 100 MB of data at a reading speed of 100 MB / s, the time may be around 1 second.

[0040] However, during the data decompression process, the data decompression speed is variable, which is related to the data content in the decompressed data block. Therefore, there will be differences in the decompression times of compressed data blocks with the same data volume. Taking the decompression speed of the electronic device as 100 MB / s (the decompression speed under macroscopic conditions, the average speed obtained by decompressing a large amount of data) as an example, when decompressing 100 MB of data, some may take 1.5 seconds, some 1 second, and some 0.5 seconds. The difference between these is much larger than the difference between the reading times.

[0041] When performing parallel reading and decompression on compressed data blocks with the same data volume, due to the large difference between the decompression time and the reading time of the data block, it may cause delays in data processing, that is, waiting for the data block to be decompressed before transmission or waiting for the data block to be read before decompression.

[0042] The above is a description when the data reading speed and decompression speed (under macroscopic conditions) of the electronic device are equal. When the data reading speed and decompression speed of the electronic device are not equal, the gap between the decompression time and the reading time of compressed data blocks with the same data volume may be even larger.

[0043] Therefore, in order to reduce this gap, this application selects to divide the compressed data block according to the data reading time and data decompression time of the compressed data block. Specifically, refer to the following embodiments.

[0044] Refer to Figure 2 , Figure 2 is a schematic flowchart of the second embodiment of the device startup method of this application. This method is a further limitation of the above embodiment. This method includes but is not limited to the following steps.

[0045] S21: Divide the startup data into multiple data sub - blocks.

[0046] When compressing the startup data into compressed data blocks based on the data reading time and data decompression time, first divide the startup data into multiple data sub - blocks.

[0047] S22: Compress each of the multiple data sub - blocks respectively to obtain corresponding multiple compressed data sub - blocks.

[0048] Each data sub-block is compressed respectively by using a compression algorithm to obtain a corresponding compressed data sub-block.

[0049] S23: Divide multiple compressed data sub-blocks to obtain at least two compressed data blocks, where the start data corresponding to the compressed data sub-blocks in a compressed data block is continuous, and both the data reading time and the data decompression time of the compressed data block are within a preset range centered on a preset time.

[0050] After obtaining multiple compressed data sub-blocks, according to the data reading time and the data decompression time, divide the multiple compressed data sub-blocks into at least two compressed data blocks, so that both the data reading time and the decompression time of these compressed data blocks are within a preset range centered on a preset time.

[0051] The start data corresponding to the compressed data in the obtained compressed data block is continuous. That is, when obtaining the compressed data block, the corresponding compressed data sub-blocks are divided and compressed in the order of the start data.

[0052] Similar to the above description, since the reading speed is usually stable, the data reading times of compressed data sub-blocks with the same data volume do not differ much.

[0053] The data decompression time of the compressed data sub-block needs to be determined according to the actual decompression situation of the compressed data sub-block.

[0054] Therefore, in the process of parallel processing of reading and decompressing compressed data, in order to further reduce the difference in reading and decompression times of the compressed data block, the present application first divides the compressed data sub-blocks to reduce the difference between the decompression time and the reading time, and then through the combination adjustment of the compressed data sub-blocks, and then according to the different decompression times of the compressed data sub-blocks, combines and divides them, so that the data reading time and the data decompression time of the obtained compressed data block are closer, thereby reducing the difference between the reading time and the decompression time during parallel processing and reducing the waiting time during parallel processing.

[0055] When the data reading speed and the data decompression speed of the electronic device differ greatly, since the difference is already large, the division of the compressed data block in the present application may not be particularly obvious in reducing the waiting time during the parallel process. However, when the data reading speed and the data decompression speed of the electronic device are similar, dividing the compressed data block according to the above embodiments of the present application can reduce more waiting time during the parallel process.

[0056] Refer to Figure 3 , Figure 3This is a schematic diagram of obtaining compressed data blocks based on data reading time and data decompression time. Taking the startup data including Image_P1 as an example, assuming the size of Image_P1 is 10MB, it is divided into units of 1MB for processing. The preset time is set to 10ms, and the corresponding preset range is set to 9 - 11ms. The size of the compressed data of the first 1MB of data (labeled ①) is 512KB, and it takes 5ms to decompress; the size of the compressed data of the second 1MB of data (labeled ②) is 480KB, and it takes 4ms to decompress. Then, the first 1MB and the second 1MB are combined into the first split compressed block Image_Z1_1. This split block compresses the first 1MB of data and the second 1MB of data. The size of the compressed data is 512KB + 480KB = 992KB, and it takes 5ms + 4ms = 9ms to decompress this data. It is expected to take (992KB) / (100MB / S) = 9.5ms to read 992KB from the storage device. In this way, the reading time and the decompression time are basically equivalent and within the preset range of the preset time. By analogy, the same processing is performed on the remaining 8 1MB of data. According to the above method, the selection and compression of 1MB data sub - blocks are carried out. The second split compressed block Image_Z1_2 can be composed of ③④⑤⑥, and the size of the compressed data is 1001KB. The third split compressed block Image_Z1_3 is composed of ⑦⑧⑨⑩, and the size of the compressed data is 1020KB, so that the data reading time and data decompression time of the obtained split compressed blocks also meet the above requirements.

[0057] In this embodiment, when obtaining the compressed data block, the startup data is divided into multiple parts to obtain multiple compressed data sub - blocks, and then they are combined to obtain the compressed data block, so that the reading time and decompression time of the obtained compressed data block are within the preset range centered on the preset time. Taking the reading time and decompression time as constraints, the size of the compressed data block is dynamically adjusted, so that during the parallel execution of reading and decompressing the compressed data block, the matching degree between the decompression time and the reading time of the compressed data block is higher and the gap is smaller, thereby further optimizing the startup process of the electronic device and reducing the startup time consumption of the electronic device.

[0058] In some embodiments, the startup data is divided into multiple data sub - blocks with a preset fixed data volume. Dividing the startup data with a fixed data volume to obtain data sub - blocks can make the data volumes of the obtained compressed data sub - blocks not differ too much, and their data reading times will not differ too much, which is convenient for the subsequent process of obtaining the division of the compressed data block.

[0059] The fixed data volume can be set according to the actual situation. For example, if the fixed data volume is 1MB, when dividing the startup data, it is divided into multiple 1MB data sub-blocks. If the fixed data volume is 2MB, when dividing the startup data, it is divided into multiple 2MB data sub-blocks. The smaller the fixed data volume, the larger the adjustment space of the compressed data sub-blocks in the compressed data block when dividing the compressed data block. Therefore, the gap between the data reading time and the data decompression time of the obtained compressed data block is smaller.

[0060] In some embodiments, before the controller reads a compressed data block from the storage device, it includes: obtaining compression parameters for decompressing the compressed data block, where the compression parameters include at least one of the following: compression algorithm type, the number of compressed data sub-blocks in each compressed data block, the offset and data volume of the compressed data block in the compressed data, the offset and data volume of the original data corresponding to the compressed data block in the startup data.

[0061] Referring to Figure 3 , after the controller obtains the compressed data block, it stores the compression parameters related to the compressed data block in the storage device together for subsequent reading and decompression of the compressed data block. The Header is used to record the compression parameters of the compressed data blocks in Image_Z1. Taking Image_Z1_1 as an example, the compression algorithm type is the compression algorithm type used to obtain the compressed data block Image_Z1_1. The offset in the compressed data is the offset position of the compressed data block Image_Z1_1 in the compressed data Image_Z1. The data volume in the compressed data is the data size of the compressed data block Image_Z1_1. The offset and data volume of the original data corresponding to the compressed data in the startup data, that is, the offset and data volume of that part of the startup data corresponding to the compressed data in the entire startup data. The offset of the original data in the startup data is the offset position of the original data ①② of the compressed data block Image_Z1_1 in the startup data Image_P1. The data volume of the original data in the startup data is the data size of the original data ①②.

[0062] The information included in the Header is the compression algorithm used and the number of compressed data blocks is 3. Assume the data capacity of the Header is 1 KB. The information included in the Header for the first compressed data block Image_Z1_1 is the offset position of Image_Z1_1 in Image_Z1, which is 1 KB, the data size of Image_Z1_1, which is 992 KB, the offset position of the corresponding original data ①② in Image_P1, which is 0, and the data size of the corresponding original data ①②, which is 2 MB. The information included in the Header for the second compressed data block Image_Z1_2 is the offset position of Image_Z1_2 in Image_Z1, which is 993 KB, the data size of Image_Z1_1, which is 1001 KB, the offset position of the corresponding original data ①② in Image_P1, which is 2 MB, and the data size of the corresponding original data ①②, which is 4 MB. The information for the remaining compressed data blocks can be inferred in this way.

[0063] Refer to Figure 4 , Figure 4 which is a schematic flowchart of the third embodiment of the device startup method of the present application. This method is a further limitation of the above embodiment. This method includes but is not limited to the following steps.

[0064] S31: When the controller reads and decompresses the compressed data blocks in the compressed data, read the compressed data blocks based on the offset and data volume of the compressed data blocks in the compressed data, and store the original data corresponding to the decompressed compressed data blocks in the running memory based on the offset and data volume of the original data corresponding to the compressed data blocks in the startup data.

[0065] The controller of the electronic device is provided with a running memory. When the controller reads and decompresses all the compressed data blocks in the compressed data to obtain the startup data, it will decompress and store the data in the running memory according to the offset and data volume in the decompression parameters.

[0066] According to the offset and data volume of the current compressed data block, the sum of the two can obtain the offset of the next compressed data block to be read. That is, the next compressed data block to be read can be determined according to the offset.

[0067] For example, the electronic device reads the Header of Image_Z1, parses out the compression algorithm used, the number of compressed data blocks, and the information of each compressed data block. According to the information of the first compressed data block Image_Z1_1, compressed data Image_Z1_1 with a data size of 992 KB is read from the offset position 1K of Image_Z1. The data ①② is decompressed from Image_Z1_1 to the 0 offset position of Image_P1. At the same time, according to the information of the second segmented compressed segment Image_Z1_2, compressed data Image_Z1_2 with a data size of 1001 KB is read from the offset position 993K of Image_Z1. The data ③④⑤⑥ is decompressed from Image_Z1_2 to the 2MB offset position of Image_P1. At the same time, according to the information of the third segmented compressed segment Image_Z1_3, compressed data Image_Z1_3 with a data size of 1020 KB is read from the offset position 1994K of Image_Z1. And so on for the decompression order of subsequent compressed data blocks.

[0068] The decompressed data is stored in the running memory in order according to the offset and data size in Image_P1.

[0069] S32: When all the compressed data blocks in the compressed data are decompressed, the startup data stored in the running memory is obtained.

[0070] After decompressing all the compressed data blocks, complete startup data can be obtained in the running memory. Using this startup data, the startup of the electronic device can be completed.

[0071] In some embodiments, the startup data includes multiple image files. The startup of an electronic device usually requires file data with multiple functions. Different image files correspond to different functions. When the startup data includes multiple image files, the startup data is divided into multiple data sub-blocks, including dividing each image file in the startup data into multiple data sub-blocks, and separately dividing the data compression blocks for each data sub-block corresponding to each image file. Each of the multiple compressed data blocks obtained from each image file has corresponding compression parameters.

[0072] Refer to Figure 5 , Figure 5 which is a schematic diagram of parallel decompression and reading of compressed data blocks in this application.

[0073] Taking the startup data including two image files Image_P1 and Image_P2 as an example, the corresponding compressed data after compression is Image_Z1 and Image_Z2. Image_Z1 and Image_Z2 have their respective compression parameters placed in the Header. In the storage device, Image_Z1 and Image_Z2 are stored in sequence, with Image_Z1 having a lower address and Image_Z2 having a higher address. When reading, the controller first reads Image_Z1. After reading the compression parameters in the Header of Image_Z1, the controller reads and decompresses the corresponding compressed data block to the operating memory according to the information of the compression parameters. Read Image_Z1_1. While decompressing Image_Z1_1, read Image_Z1_2. While decompressing Image_Z1_2, read Image_Z1_3. When all of Image_Z1 has been read, read the next image file Image_Z2. The Header of Image_Z2 can be read after Image_Z1_3 has been decompressed. Or the Header of Image_Z2 can be read when Image_Z1_3 starts to be decompressed, which is faster and improves the startup speed of the electronic device. Reading and decompressing Image_Z2 is similar to the above.

[0074] Referring to Figure 6 , Figure 6 is a schematic structural diagram of an embodiment of the startup device of the present application.

[0075] The startup device includes a storage module 110 and a control module 120.

[0076] The storage module 110 is used to store compressed data, and the compressed data includes compressed data blocks, and the compressed data blocks in the compressed data are obtained by compressing the startup data of the startup device.

[0077] The control module 120 is used to, in response to the startup device being powered on, read the compressed data blocks in the compressed data from the storage module 110, read the next compressed data block while decompressing the current compressed data block, until all compressed data blocks are decompressed, read and decompress all compressed data blocks in the compressed data to obtain startup data, and use the startup data to control the startup of the startup device.

[0078] In some embodiments, the compressed data blocks are obtained by compressing the startup data based on the data reading time and the data decompression time.

[0079] In some embodiments, when the control module compresses the startup data based on the data reading time and the data decompression time, it first divides the startup data into multiple data sub-blocks, then compresses the multiple data sub-blocks separately to obtain corresponding multiple compressed data sub-blocks, and then divides the multiple compressed data sub-blocks to obtain at least two compressed data blocks. The startup data corresponding to the compressed data sub-blocks in the compressed data block is continuous, and the transmission time and decompression time of each compressed data block are both within a preset range centered on a preset time.

[0080] In some embodiments, the control module divides the startup data into multiple data sub-blocks with a preset fixed data volume. Dividing the startup data into data sub-blocks with a fixed data volume can make the data volumes of the obtained compressed data sub-blocks not differ too much, and their transmission times will not differ too much, facilitating the subsequent process of dividing the compressed data blocks.

[0081] In some embodiments, before the control module reads the compressed data block in the compressed data from the storage device, it includes: obtaining compression parameters for decompressing the compressed data block. The compression parameters include at least one of the following: compression algorithm type, the number of compressed data sub-blocks in each compressed data block, the offset and data volume of the compressed data block in the compressed data, and the offset and data volume of the original data corresponding to the compressed data block in the startup data.

[0082] In some embodiments, when the control module reads and decompresses the compressed data block in the compressed data, it reads the compressed data block based on the offset and data volume of the compressed data block in the compressed data, and stores the original data corresponding to the decompressed compressed data block in the operating memory of the control module based on the offset and data volume of the original data corresponding to the compressed data block in the startup data. When all the compressed data blocks in the compressed data are decompressed, the startup data stored in the operating memory is obtained.

[0083] In some embodiments, the startup data includes multiple image files. The startup of the startup device usually requires file data for multiple functions. Different image files correspond to different functions. When the startup data includes multiple image files, dividing the startup data into multiple data sub-blocks includes dividing each image file in the startup data into multiple data sub-blocks separately, and dividing the data compression blocks corresponding to the data sub-blocks of each image file separately. Each image file has corresponding compression parameters for the obtained multiple compressed data blocks.

[0084] As Figure 7 shown, Figure 7 is a schematic structural diagram of an embodiment of an electronic device according to the present application.

[0085] The electronic device includes a processor 210 and a memory 220.

[0086] The processor 210 controls the operation of the electronic device. The processor 210 may also be referred to as a CPU (Central Processing Unit).
