In an embodiment, an execution body of the information obtaining method according to the embodiment of the present application may be a Central Processing Unit (CPU).

In the embodiment of the application, the information to be acquired has identification information for distinguishing different information to be acquired. It should be noted that the types of the information to be acquired and the identification information are not limited too much.

In an embodiment, in an application scenario of image transformation, the information to be acquired may include pixel information of a pixel point in the image, and the identification information may include position information of the pixel point.

In an embodiment of the present application, a cache memory cache has a plurality of sub-caches. It should be noted that the number of the sub-caches is not limited too much, for example, the number of the sub-caches may be 2.

In one embodiment, the cache includes a first sub-cache and a second sub-cache, where the first sub-cache is a memory on the chip and the second sub-cache is a hardware register on the chip.

Optionally, the storage capacity of the first sub-cache is greater than that of the second sub-cache, the first sub-cache acquires and stores the cache information of the first storage unit from the memory at one time, and the second sub-cache acquires 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 larger than that of the second storage unit, and the sizes of the first storage unit and the second storage unit are not limited too much, for example, the first storage unit is 64 bits (bit), and the second storage unit is 8 bits.

In one embodiment, the information to be stored can be obtained from the memory, the information to be stored is stored in the first sub-cache, and part of the information to be stored is stored in the second sub-cache. For example, 64-bit pixel information of the pixel point a can be acquired from the memory, the 64-bit pixel information of the pixel point a is stored into the first sub-cache, 8-bit pixel information is screened out from the 64-bit pixel information of the pixel point a, and the screened 8-bit pixel information of the pixel point a is stored into the second sub-cache.

In the embodiment of the application, the information to be acquired can be queried in parallel based on a plurality of sub-caches of the identification information in the cache, that is, the information to be acquired can be queried simultaneously in the plurality of sub-caches based on the identification information. Continuing to take the example that the cache comprises the first sub-cache and the second sub-cache, the information to be acquired can be parallelly queried in the first sub-cache and the second sub-cache based on the identification information.

In one embodiment, the identification information of the information to be acquired and the storage position of the information to be acquired in the sub-cache have a corresponding relationship. It can be understood that the storage locations of the same sub-cache corresponding to the identification information of different information to be acquired may be different, and the storage locations of different sub-caches corresponding to the identification information of the same information to be acquired may be different.

In the embodiment of the application, the sub-cache may store information to be acquired or may not store the information to be acquired.

In the embodiment of the application, the priority can be set for the sub-caches in advance, and the priority of the sub-caches is inversely related to the stored information amount. And continuing taking the example that the cache comprises a first sub-cache and a second sub-cache, wherein the information quantity stored by the first sub-cache is larger than that stored by the second sub-cache, and the priority of the second sub-cache is higher than that of the first sub-cache.

In the embodiment of the 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 is acquired, and the candidate sub-cache with the highest priority is determined as the first target sub-cache, that is, the candidate sub-cache with the least amount of stored information is determined as the first target sub-cache, and the first target sub-cache stores the information to be acquired.

It is understood that the number of candidate sub-caches may be one or more, and is not limited herein.

And S104, obtaining the information to be obtained from the first target sub-cache.

In the embodiment of the application, the information to be acquired can be acquired from the first target sub-cache, that is, the information to be acquired is acquired from the candidate sub-cache with the least amount of stored information.

Continuing to take the example that the cache comprises a first sub-cache and a second sub-cache, wherein the priority of the second sub-cache is higher than that of the first sub-cache, if the information to be acquired is stored in response to the first sub-cache and the second sub-cache, determining the second sub-cache as a first target sub-cache, and acquiring the information to be 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, so that the operation times of the first sub-cache can be reduced, and the power consumption is reduced.

Or, if the information to be acquired is stored in response to the first sub-cache and the information to be acquired is not stored in the second sub-cache, determining that the first sub-cache is the first target sub-cache, and acquiring the information to be acquired from the first target sub-cache. Therefore, the method can acquire the information to be acquired from the first sub-cache when the first sub-cache stores the information to be acquired and the second sub-cache does not store the information to be acquired.

In one embodiment, the identification information of the information to be acquired and the storage position of the information to be acquired in the sub-cache have a corresponding relationship. And obtaining the information to be obtained from the first target sub-cache, which may include determining a storage position of the first target sub-cache corresponding to the identification information of the information to be obtained based on the correspondence, and obtaining the information to be obtained at the storage position of the first target sub-cache.

To sum up, according to the information acquisition method of the embodiment of the application, the information to be acquired can be queried in parallel by a plurality of sub-caches in the cache based on the identification information of the information to be acquired, the query speed of the caches is effectively improved by parallel query, the candidate sub-cache with the highest priority can be determined as the first target sub-cache, the candidate sub-cache is the sub-cache storing the information to be acquired, 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, the information acquisition duration is effectively shortened, the power consumption required by information acquisition is reduced, and the information acquisition is more convenient and faster.

On the basis of any of the above embodiments, after the information to be acquired is acquired from the first target sub-caches in step S104, the information to be acquired may be stored into each second target sub-cache, where the second target sub-caches are sub-caches that do not store the information to be acquired.

And continuing taking the example that the cache comprises a first sub-cache and a second sub-cache, responding to the condition that the first sub-cache stores information to be acquired and the second sub-cache does not store the information to be acquired, determining that the first sub-cache is a first target sub-cache and the second sub-cache is a second target sub-cache, acquiring the information to be acquired from the first sub-cache, and storing the information to be acquired into the second sub-cache.

Therefore, the method can store the information to be acquired into each sub-cache which does not store the information to be acquired, can update the cache information of the sub-caches in real time, and is beneficial to improving the query hit rate of the sub-caches.

On the basis of any of the above embodiments, as shown in fig. 2, after the information to be acquired is acquired from the first target sub-cache in step S104, the method may include:

s201, determining the candidate sub-cache with the lowest priority as a third target sub-cache.

In the embodiment of the application, the candidate sub-cache with the lowest priority can be determined as the third target sub-cache, that is, the candidate sub-cache with the largest information storage amount is determined as the third target sub-cache, and the third target sub-cache stores information to be acquired.

Taking the example that the caches include 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 sequentially increased, if the information to be acquired is stored in response to the first sub-cache and the second sub-cache, and the information to be acquired is not stored in the third sub-cache and the fourth sub-cache, it may be determined that the first sub-cache and the second sub-cache are candidate sub-caches at this time, and the first sub-cache is a third target sub-cache.

S202, inquiring information to be stored in the third target sub-cache based on the identification information, wherein the information to be stored at least comprises information to be acquired.

In the embodiment of the 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 comprises the information to be acquired. For example, the information to be acquired may be 8-bit pixel information of the pixel point a, 64-bit pixel information of the pixel point a may be queried in the third target sub-cache based on the position information of the pixel point a, and the 64-bit pixel information of the pixel point a includes the 8-bit pixel information of the pixel point a, and the 64-bit pixel information of the pixel point a is used as the information to be stored.

In one embodiment, the identification information of the information to be acquired and the storage position of the information to be stored in the sub-cache have a corresponding relationship. 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 can be understood that the storage positions of the information to be stored corresponding to the identification information of different information to be acquired in the same sub-cache may be different, and the storage positions of the information to be stored corresponding to the identification information of the same information to be acquired in different sub-caches may be different. Querying the information to be stored in the third target sub-cache based on the identification information, which may include determining a storage location of the information to be stored corresponding to the identification information of the information to be obtained in the third target sub-cache based on the correspondence, and querying the information to be stored in the storage location of the third target sub-cache.

S203, storing the inquired information to be stored into each second target sub-cache, wherein the second target sub-caches are sub-caches which do not store the information to be acquired.

Continuing to take the example that the caches include a first sub-cache, a second sub-cache, a third sub-cache and a fourth sub-cache, wherein the priorities of the first sub-cache, the second sub-cache, the third sub-cache and the fourth sub-cache are sequentially increased, if the information to be acquired is stored in response to the first sub-cache and the second sub-cache, and the information to be acquired is not stored in the third sub-cache and the fourth sub-cache, the first sub-cache and the second sub-cache can be determined as candidate sub-caches at the moment, and the first sub-cache is a third target sub-cache, and the third sub-cache and the fourth sub-cache can be determined as a second target sub-cache.

Further, information to be stored can be queried in the first sub-cache based on the identification information, the information to be stored at least comprises information to be acquired, and the information to be stored is stored in the third sub-cache and the fourth sub-cache.

Therefore, the method can determine that the candidate sub-cache with the lowest priority is the third target sub-cache, and query information to be stored in the third target sub-cache based on the identification information, wherein the information to be stored at least comprises information to be acquired, store the queried information to be stored into each sub-cache which does not store the information to be acquired, and update more cache information into the sub-caches compared with the situation that the information to be acquired is only stored into each sub-cache which does not store the information to be acquired, thereby being beneficial to improving the query hit rate of the sub-caches.

On the basis of any of the above embodiments, after the information to be acquired is concurrently queried by the multiple sub-caches in the cache memory based on the identification information in step S102, the method may further include, in response to that any sub-cache does not store the information to be acquired, querying the information to be acquired in the memory based on the identification information, and acquiring the queried information to be acquired.

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 can be understood that the storage locations of the memories 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 a storage location of the memory corresponding to the identification information of the information to be acquired based on the correspondence, and querying the information to be acquired at the storage location of the memory.

Therefore, when any sub-cache does not store the information to be acquired, the method can inquire the information to be acquired in the memory based on the identification information and acquire the inquired information to be acquired from the memory.

On the basis of any of the above embodiments, after the queried information to be obtained is obtained, the queried information to be obtained may also be stored in each sub-cache.

Continuing to take the example that the cache comprises the first sub-cache and the second sub-cache, if the first sub-cache and the second sub-cache do not store the information to be acquired in response to the response, querying the information to be acquired in the memory based on the identification information, acquiring the queried information to be acquired, and storing the queried information to be acquired into the first sub-cache and the second sub-cache respectively.

In the embodiment of the application, the information to be stored can be queried in the memory based on the identification information, and the information to be stored at least comprises the information to be acquired. For example, the information to be acquired may be 8-bit pixel information of the pixel point a, 64-bit pixel information of the pixel point a may be queried in the memory based on the position information of the pixel point a, and the 64-bit pixel information of the pixel point a includes the 8-bit pixel information of the pixel point a, and the 64-bit pixel information of the pixel point a is used as the information to be stored.

In one embodiment, the identification information of the information to be acquired and the storage position of the information to be stored in the memory have a corresponding relationship.

Therefore, the method can store the information to be stored, which is queried from the memory, into each sub-cache, and can update more cache information into the sub-caches compared with the method that the information to be acquired is only stored into each sub-cache, thereby being beneficial to improving the query hit rate of the sub-caches.

On the basis of any of the above embodiments, storing the queried information to be stored into each sub-cache may include sorting the plurality of sub-caches from low to high according to priority, storing the queried information to be stored into a first sub-cache, storing part of the queried information to be stored as first information to be stored into a second sub-cache, storing part of the first information to be stored as second information to be stored into a third sub-cache, and ending the storage of the last sub-cache, where the first information to be stored and the second information to be stored at least include information to be acquired.

Continuing to take the example that the cache comprises 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 sequentially increased, if the first sub-cache, the second sub-cache, the third sub-cache and the fourth sub-cache do not store the information to be acquired, the information to be stored can be inquired in the memory based on the identification information, and the information to be stored at least comprises the information to be acquired.

Further, the sub-caches can be sorted from low to high according to the priority, the sorting results are a first sub-cache, a second sub-cache, a third sub-cache and a fourth sub-cache, the inquired information to be stored can be stored in the first sub-cache, part of the inquired information to be stored is stored in the second sub-cache as the first information to be stored, part of the first information to be stored is stored in the third sub-cache as the second information to be stored, and part of the second information to be stored is stored in the fourth sub-cache as the third information to be stored.

Or, if the information to be acquired is stored in response to the first sub-cache and the second sub-cache, and the information to be acquired is not stored in the third sub-cache and the fourth sub-cache, it may be determined that the first sub-cache and the second sub-cache are candidate sub-caches, the first sub-cache is a third target sub-cache, and it may also be determined that the third sub-cache and the fourth sub-cache are second target sub-caches, the information to be stored may 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 acquired.

Further, the third sub-cache and the fourth sub-cache can be sorted from low to high according to the priority, and the sorting result is the third sub-cache and the fourth sub-cache, so that the inquired information to be stored can be stored into the third sub-cache, and part of the inquired information to be stored is stored into the fourth sub-cache as the first information to be stored.

Therefore, the method can store the inquired information to be stored into the sub-caches according to the priorities of the sub-caches, and can ensure that the information amount stored by the sub-caches is negatively related to the priorities.

On the basis of any of the above embodiments, after the queried information to be acquired or information to be stored is stored in each sub-cache, the step S102 of parallelly querying the information to be acquired and the subsequent steps thereof in the cache based on the identification information may be returned to continue to be executed. Therefore, after the information to be acquired or the information to be stored, which is inquired from the memory, is stored in each sub-cache, the method can continue to inquire the information to be acquired in the sub-caches in parallel based on the identification information, and further acquire the information to be acquired from the caches.
