[0002] At present, cache memory has advantages such as fast access speed and is widely used to store memory information. When the central processing unit (CPU) needs to obtain memory information, it can first query in the cache. If the cache stores the memory information to be obtained, the memory information is obtained from the cache, and the information can be obtained without accessing the memory. However, the information acquisition method in the related art has the problem of long information acquisition time and high power consumption. Summary of the invention

[0042] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0043] The following describes the information acquisition method, device, electronic device and storage medium of the embodiments of the present application with reference to the accompanying drawings.

[0044] Figure 1 The figure is a flowchart of an information acquisition method according to an embodiment of the present application.

[0045] like Figure 1 As shown, the information acquisition method of the embodiment of the present application includes:

[0046] S101, obtaining identification information of information to be obtained.

[0047] It should be noted that the execution subject of the information acquisition method of the embodiment of the present application may be an information acquisition device, and the information acquisition device of the embodiment of the present application may be configured in any electronic device so that the electronic device can execute the information acquisition method of the embodiment of the present application. Among them, the electronic device may be a personal computer (PC), a cloud device, a mobile device, etc., and the mobile device may be, for example, a mobile phone, a tablet computer, a personal digital assistant, a wearable device, a vehicle-mounted device, and other hardware devices with various operating systems, touch screens, and / or display screens. In one embodiment, the execution subject of the information acquisition method of the embodiment of the present application may be a central processing unit (CPU).

[0048] In the embodiment of the present application, the information to be acquired has identification information for distinguishing different information to be acquired. It should be noted that there are no excessive restrictions on the types of the information to be acquired and the identification information.

[0049] In one implementation, in an image transformation application scenario, the information to be acquired may include pixel information of pixels in the image, and the identification information may include position information of the pixels.

[0050] In one implementation, in a speech synthesis application scenario, the information to be acquired may include text information, and the identification information may include speaker identification information (such as speaker name, account number, etc.).

[0051] S102, querying multiple sub-caches in the cache memory cache in parallel for information to be acquired based on the identification information.

[0052] In the embodiment of the present application, the cache memory cache has a plurality of sub-caches. It should be noted that there is no excessive limitation on the number of sub-caches, for example, the number of sub-caches may be 2.

[0053] In one implementation, the cache includes a first sub-cache and a second sub-cache, the first sub-cache is a memory on a chip, and the second sub-cache is a hardware register on the chip.

[0054] Optionally, the storage capacity of the first sub-cache is greater than the storage capacity of the second sub-cache, the first sub-cache obtains and stores the cache information of the first storage unit from the memory at one time, and the second sub-cache obtains and stores the cache information of the second storage unit from the memory or the first sub-cache at one time. The size of the first storage unit is greater than the size of the second storage unit, and the sizes of the first storage unit and the second storage unit are not excessively limited, for example, the first storage unit is 64 bits (bit) and the second storage unit is 8 bits.

[0055] Optionally, the amount of information stored in the first sub-cache is greater than the amount of information stored in the second sub-cache. In one embodiment, the information to be stored may be obtained from the memory, and the information to be stored may be stored in the first sub-cache, and part of the information to be stored may be stored in the second sub-cache. For example, the 64-bit pixel information of pixel point A may be obtained from the memory, the 64-bit pixel information of pixel point A may be stored in the first sub-cache, 8-bit pixel information may be filtered out from the 64-bit pixel information of pixel point A, and the filtered 8-bit pixel information of pixel point A may be stored in the second sub-cache.

[0056] In an embodiment of the present application, multiple sub-caches in the cache may be queried in parallel for information to be acquired based on identification information, that is, multiple sub-caches may be queried in parallel for information to be acquired based on identification information. Continuing with the example of a cache including a first sub-cache and a second sub-cache, information to be acquired may be queried in parallel in the first sub-cache and the second sub-cache based on identification information.

[0057] In one embodiment, the identification information of the information to be obtained has a corresponding relationship with the storage location of the information to be obtained in the sub-cache. It is understandable that the storage locations of the same sub-cache corresponding to different identification information of the information to be obtained may be different, and the storage locations of different sub-caches corresponding to the identification information of the same information to be obtained may be different. Querying the information to be obtained in the sub-cache based on the identification information may include determining the storage location of the sub-cache corresponding to the identification information of the information to be obtained based on the above-mentioned corresponding relationship, and querying the information to be obtained at the storage location of the sub-cache.

[0058] S103, in response to the existence of at least one candidate sub-cache storing information to be obtained, obtaining priorities of the candidate sub-caches, and determining the candidate sub-cache with the highest priority as the first target sub-cache, wherein the priority of the sub-cache is negatively correlated with the amount of stored information.

[0059] In the embodiment of the present application, the sub-cache may store the information to be obtained, or may not store the information to be obtained.

[0060] In an embodiment of the present application, a priority may be set for a sub-cache in advance, and the priority of the sub-cache is negatively correlated with the amount of information stored. Continuing to take the example that the cache includes a first sub-cache and a second sub-cache, the amount of information stored in the first sub-cache is greater than the amount of information stored in the second sub-cache, and the priority of the second sub-cache is higher than the priority of the first sub-cache.

[0061] In an embodiment of the present application, in response to the existence of at least one candidate sub-cache storing information to be acquired, the priority of the candidate sub-cache can be obtained, and the candidate sub-cache with the highest priority can be determined as the first target sub-cache, that is, the candidate sub-cache storing the least amount of information can be determined as the first target sub-cache, and the first target sub-cache stores the information to be acquired.

[0062] It is understandable that the number of candidate sub-caches may be one or more, and no further limitation is given here.

[0063] S104: Obtain the information to be obtained from the first target sub-cache.

[0064] In the embodiment of the present application, the information to be acquired may be acquired from the first target sub-cache, that is, the information to be acquired may be acquired from the candidate sub-cache storing the least amount of information.

[0065] Continuing with the example that the cache includes the first sub-cache and the second sub-cache, the priority of the second sub-cache is higher than the priority of the first sub-cache. If the first sub-cache and the second sub-cache store information to be acquired, the second sub-cache is determined to be the first target sub-cache, and the information to be acquired is acquired from the first target sub-cache. Therefore, when the first sub-cache and the second sub-cache both store information to be acquired, the method preferentially acquires the information to be acquired from the second sub-cache, which can reduce the number of operations on the first sub-cache and help reduce power consumption.

[0066] Alternatively, in response to the first sub-cache storing the information to be obtained and the second sub-cache not storing the information to be obtained, the first sub-cache is determined to be the first target sub-cache, and the information to be obtained is obtained from the first target sub-cache. Thus, when the first sub-cache stores the information to be obtained and the second sub-cache does not store the information to be obtained, the method can obtain the information to be obtained from the first sub-cache.

[0067] In one embodiment, the identification information of the information to be obtained has a corresponding relationship with the storage location of the information to be obtained in the sub-cache. Acquiring the information to be obtained from the first target sub-cache may include determining the storage location of the first target sub-cache corresponding to the identification information of the information to be obtained based on the corresponding relationship, and acquiring the information to be obtained at the storage location of the first target sub-cache.

[0068] In summary, according to the information acquisition method of the embodiment of the present application, the information to be acquired can be queried in parallel in multiple sub-caches in the cache memory cache based on the identification information of the information to be acquired. The parallel query effectively improves the query speed of the cache, and can determine the candidate sub-cache with the highest priority as the first target sub-cache. The candidate sub-cache is the sub-cache that stores the information to be acquired, and the information to be stored is acquired from the first target sub-cache. The information to be acquired can be acquired from the candidate sub-cache with the least amount of stored information, which effectively shortens the time for information acquisition, reduces the power consumption required for information acquisition, and makes it more convenient and quick to acquire information.

[0069] Based on any of the above embodiments, after obtaining the information to be obtained from the first target sub-cache in step S104, the step may include storing the information to be obtained in each second target sub-cache, where the second target sub-cache is a sub-cache that does not store the information to be obtained.

[0070] Continuing with the example of a cache including a first sub-cache and a second sub-cache, in response to the first sub-cache storing information to be obtained and the second sub-cache not storing the information to be obtained, it can be determined that the first sub-cache is the first target sub-cache and the second sub-cache is the second target sub-cache, and the information to be obtained is obtained from the first sub-cache and stored in the second sub-cache.

[0071] Therefore, the method can store the information to be obtained in each sub-cache that does not store the information to be obtained, and can update the cache information of the sub-cache in real time, which helps to improve the query hit rate of the sub-cache.

[0072] Based on any of the above embodiments, Figure 2As shown, after obtaining the information to be obtained from the first target sub-cache in step S104, the following may be included:

[0073] S201: Determine a candidate sub-cache with the lowest priority as a third target sub-cache.

[0074] In an embodiment of the present application, the candidate sub-cache with the lowest priority may be determined as the third target sub-cache, that is, the candidate sub-cache storing the largest amount of information may be determined as the third target sub-cache, and the third target sub-cache stores the information to be acquired.

[0075] Taking the cache including the first sub-cache, the second sub-cache, the third sub-cache and the fourth sub-cache as an example, the priorities of the first sub-cache, the second sub-cache, the third sub-cache and the fourth sub-cache are increased in sequence. If, in response to the first sub-cache and the second sub-cache storing information to be obtained, and the third sub-cache and the fourth sub-cache do not store information to be obtained, then at this time, it can be determined that the first sub-cache and the second sub-cache are candidate sub-caches, and the first sub-cache is the third target sub-cache.

[0076] S202: Search the third target sub-cache for information to be stored based on the identification information, where the information to be stored at least includes information to be obtained.

[0077] In an embodiment of the present application, the information to be stored can be queried in the third target sub-cache based on the identification information, and the information to be stored at least includes the information to be acquired. For example, the information to be acquired can be 8-bit pixel information of pixel point A, and the 64-bit pixel information of pixel point A can be queried in the third target sub-cache based on the position information of pixel point A, and the 64-bit pixel information of pixel point A includes the above-mentioned 8-bit pixel information of pixel point A, and the 64-bit pixel information of pixel point A is used as the information to be stored.

[0078] In one embodiment, the identification information of the information to be acquired has a corresponding relationship with the storage location of the information to be stored in the sub-cache. For example, the identification information of the information to be stored is the same as the identification information of the information to be acquired. It is understandable that the information to be stored corresponding to the identification information of different information to be acquired may have different storage locations in the same sub-cache, and the information to be stored corresponding to the identification information of the same information to be acquired may have different storage locations in different sub-caches. Querying the information to be stored in the third target sub-cache based on the identification information may include determining the storage location of the information to be stored corresponding to the identification information of the information to be acquired in the third target sub-cache based on the above-mentioned corresponding relationship, and querying the information to be stored at the storage location of the third target sub-cache.

[0079] S203: Store the retrieved information to be stored in each second target sub-cache, where the second target sub-cache is a sub-cache that does not store the information to be obtained.

[0080] Continuing with the example of a cache including a first sub-cache, a second sub-cache, a third sub-cache, and a fourth sub-cache, the priorities of the first sub-cache, the second sub-cache, the third sub-cache, and the fourth sub-cache are increased in sequence. If, in response to the first sub-cache and the second sub-cache storing information to be acquired, and the third sub-cache and the fourth sub-cache not storing information to be acquired, then at this time, the first sub-cache and the second sub-cache can be determined as candidate sub-caches, and the first sub-cache can be determined as the third target sub-cache, and the third sub-cache and the fourth sub-cache can also be determined as the second target sub-cache.

[0081] Further, the information to be stored may be searched in the first sub-cache based on the identification information, the information to be stored at least includes the information to be obtained, and the information to be stored is stored in the third sub-cache and the fourth sub-cache.

[0082] Therefore, the method can determine that the candidate sub-cache with the lowest priority is the third target sub-cache, and query the information to be stored in the third target sub-cache based on the identification information, where the information to be stored at least includes the information to be obtained, and store the queried information to be stored in each sub-cache that does not store the information to be obtained. Compared with only storing the information to be obtained in each sub-cache that does not store the information to be obtained, more cached information can be updated to the sub-cache, which helps to improve the query hit rate of the sub-cache.

[0083] Based on any of the above embodiments, after the multiple sub-caches in the cache memory cache are searched in parallel for the information to be obtained based on the identification information in step S102, it may also include, in response to any sub-cache not storing the information to be obtained, searching the memory for the information to be obtained based on the identification information, and obtaining the queried information to be obtained.

[0084] Continuing with the example that the cache includes a first sub-cache and a second sub-cache, if the first sub-cache and the second sub-cache do not store the information to be obtained, the information to be obtained can be queried in the memory based on the identification information, and the queried information to be obtained can be obtained.

[0085] In one embodiment, the identification information of the information to be acquired has a corresponding relationship with the storage location of the information to be acquired in the memory. It is understandable that the storage location of the memory corresponding to the identification information of different information to be acquired may be different. Querying the information to be acquired in the memory based on the identification information may include determining the storage location of the memory corresponding to the identification information of the information to be acquired based on the above-mentioned corresponding relationship, and querying the information to be acquired at the storage location in the memory.

[0086] Therefore, when any sub-cache does not store the information to be obtained, the method can query the information to be obtained in the memory based on the identification information, and obtain the queried information to be obtained from the memory.

[0087] On the basis of any of the above embodiments, after obtaining the queried information to be obtained, the method may further include storing the queried information to be obtained in each sub-cache.

[0088] Continuing with the example of a cache including a first sub-cache and a second sub-cache, if in response to the fact that neither the first sub-cache nor the second sub-cache stores the information to be obtained, the information to be obtained can be queried in the memory based on the identification information, and the queried information to be obtained can be obtained, and the queried information to be obtained can be stored in the first sub-cache and the second sub-cache respectively.

[0089] Therefore, the method can store the information to be obtained from the memory in each sub-cache, and can update the cache information of the sub-cache in real time, which helps to improve the query hit rate of the sub-cache.

[0090] Based on any of the above embodiments, Figure 3 As shown, after obtaining the queried information to be obtained, it also includes:

[0091] S301, searching the memory for information to be stored based on identification information, where the information to be stored at least includes information to be obtained.

[0092] In an embodiment of the present application, the information to be stored can be queried in the memory based on the identification information, and the information to be stored includes at least the information to be acquired. For example, the information to be acquired can be the 8-bit pixel information of pixel point A, and the 64-bit pixel information of pixel point A can be queried in the memory based on the position information of pixel point A, and the 64-bit pixel information of pixel point A includes the above-mentioned 8-bit pixel information of pixel point A, and the 64-bit pixel information of pixel point A is used as the information to be stored.

[0093] In one embodiment, the identification information of the information to be acquired has a corresponding relationship with the storage location of the information to be stored in the memory. For example, the identification information of the information to be stored is the same as the identification information of the information to be acquired. It is understandable that the storage locations of the information to be stored in the memory corresponding to the identification information of different information to be acquired may be different. Querying the information to be stored in the memory based on the identification information may include determining the storage location of the information to be stored in the memory corresponding to the identification information of the information to be acquired based on the above-mentioned corresponding relationship, and querying the information to be stored at the storage location in the memory.

[0094] S302: Store the retrieved information to be stored in each sub-cache.

[0095] Continuing with the example of a cache including a first sub-cache and a second sub-cache, if in response to the fact that neither the first sub-cache nor the second sub-cache stores information to be obtained, the information to be stored can be queried in the memory based on the identification information, and the information to be stored at least includes the information to be obtained, and the queried information to be stored is stored in the first sub-cache and the second sub-cache, respectively.

[0096] Therefore, this method can store the information to be stored retrieved from the memory in each sub-cache. Compared with only storing the information to be obtained in each sub-cache, more cache information can be updated to the sub-cache, which helps to improve the query hit rate of the sub-cache.

[0097] Based on any of the above embodiments, storing the queried information to be stored in each sub-cache may include sorting multiple sub-caches from low to high priority, storing the queried information to be stored in the first-ranked sub-cache, and storing part of the queried information to be stored as first information to be stored in the second-ranked sub-cache, and storing part of the first information to be stored as second information to be stored in the third-ranked sub-cache, until the storage of the last-ranked sub-cache is completed, wherein the first information to be stored and the second information to be stored at least include information to be obtained.

[0098] Continuing with the example that the cache includes the first sub-cache, the second sub-cache, the third sub-cache, and the fourth sub-cache, the priorities of the first sub-cache, the second sub-cache, the third sub-cache, and the fourth sub-cache are increased in sequence. If, in response to the first sub-cache, the second sub-cache, the third sub-cache, and the fourth sub-cache not storing information to be obtained, the information to be stored can be queried in the memory based on the identification information, and the information to be stored at least includes the information to be obtained.

[0099] Furthermore, multiple sub-caches can be sorted from low to high according to priority, and the sorting result is the first sub-cache, the second sub-cache, the third sub-cache, and the fourth sub-cache. The queried information to be stored can be stored in the first sub-cache, and part of the queried information to be stored can be stored in the second sub-cache as the first information to be stored, and part of the first information to be stored can be stored in the third sub-cache as the second information to be stored, and part of the second information to be stored can be stored in the fourth sub-cache as the third information to be stored.

[0100] Alternatively, in response to the first sub-cache and the second sub-cache storing information to be obtained, and the third sub-cache and the fourth sub-cache not storing information to be obtained, then at this time it can be determined that the first sub-cache and the second sub-cache are candidate sub-caches, and the first sub-cache is the third target sub-cache, and it can also be determined that the third sub-cache and the fourth sub-cache are the second target sub-cache, then the information to be stored can be queried in the first sub-cache based on the identification information, and the information to be stored at least includes the information to be obtained.

[0101] Furthermore, the third sub-cache and the fourth sub-cache may be sorted from low to high priority, and the sorting result is the third sub-cache and the fourth sub-cache. The queried information to be stored may be stored in the third sub-cache, and part of the queried information to be stored may be stored in the fourth sub-cache as the first information to be stored.

[0102] Therefore, the method can store the queried information to be stored in the sub-cache according to the priority of the sub-cache, and can ensure that the amount of information stored in the sub-cache is negatively correlated with the priority.

[0103] Based on any of the above embodiments, after the queried information to be obtained or to be stored is stored in each sub-cache, the method can return to continue to perform step S102 of querying the information to be obtained in parallel in multiple sub-caches in the cache memory based on the identification information and subsequent steps. Thus, after the information to be obtained or to be stored queried from the memory is stored in each sub-cache, the method can continue to query the information to be obtained in parallel in multiple sub-caches based on the identification information, and then obtain the information to be obtained from the cache.

[0104] In order to make those skilled in the art understand this application more clearly, Figure 4 is a flowchart of an information acquisition method according to a specific example of the present application, such as Figure 4 As shown, the information acquisition method may include the following steps:

[0105] S401, obtaining identification information of information to be obtained.

[0106] S402, querying multiple sub-caches in the cache in parallel for information to be acquired based on the identification information.

[0107] S403: Determine whether there is at least one candidate sub-cache storing information to be obtained.

[0108] If yes, execute step S404; if no, execute step S407.

[0109] S404, obtaining priorities of candidate sub-caches, and determining the candidate sub-cache with the highest priority as the first target sub-cache, wherein the priority of the sub-cache is negatively correlated with the amount of stored information.

[0110] S405: Obtain the information to be obtained from the first target sub-cache.

[0111] S406: Store the information to be acquired in each second target sub-cache, where the second target sub-cache is a sub-cache that does not store the information to be acquired.

[0112] S407, searching the memory for information to be obtained based on the identification information, and obtaining the found information to be obtained.

[0113] S408, storing the queried information to be obtained in each sub-cache, and returning to continue executing step S402 and subsequent steps.
