[0054] The core of the present invention is to provide a method, device, equipment and computer-readable storage medium for storing operation data, which can determine several cache pages in the memory device, and then when writing the operation data to the memory device, the operation data can be written into the cache page corresponding to the target module set (the module set where the functional sub-module to which the operation data to be cached belongs is located). That is, in the present invention, the functional sub-modules in the central processing unit are divided into sets, and the operation data generated by the functional sub-modules in each module set are independently cached, so that the operation data in the memory device can be used in units of module sets, eliminating the steps of manual classification and improving the convenience of using the operation data and the analysis efficiency.

[0055] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] Please refer to Figure 1 , Figure 1 A schematic flow chart of a method for storing running data provided by the present invention, wherein the method for storing running data is applied to a central processing unit of a data processing device, comprising:

[0057] S101: In a memory device, determining a plurality of cache pages for storing operating data;

[0058] Specifically, taking into account the technical problems in the above background technology, and considering the need to classify the "operation data generated by the central processing unit" when using it, that is, when faced with multiple types of operation data that are mixed together, these operation data need to be classified before they can be processed, and considering that if these operation data are automatically classified and cached in the caching stage, then it will be beneficial to directly use the classified cached operation data without classification, thereby improving work efficiency. Therefore, in an embodiment of the present invention, classified caching is intended to be performed in the caching stage of the operation data, and in an embodiment of the present invention, various types of operation data are distinguished and cached through multiple cache pages. Therefore, in this step, for the central processing unit, a number of cache pages for storing operation data can be determined in the memory device, so that the operation data can be classified and cached later.

[0059] The total number of cache pages may be set independently, and the embodiment of the present invention does not limit this.

[0060] S102: determining a cache page corresponding to a target module set from cache pages of a memory device, and using the cache page as a target cache page, wherein the target module set is: a module set where a functional submodule to which the running data to be cached belongs is located;

[0061] Specifically, considering that the operating data generated by the set (module set) formed by certain functional sub-modules running in the central processing unit is suitable for caching as a category, in an embodiment of the present invention, the functional sub-modules in the central processing unit are pre-formed into multiple module sets, each module set includes at least one functional sub-module, and then the operating data generated by the functional sub-modules in a single module set are cached in the corresponding cache page, so that the "classification of operating data according to the module set" can be realized. Therefore, when the operating data to be cached is generated, the "module set to which the functional sub-module to which the operating data to be cached belongs" can be first determined, that is, the target module set is determined, and then the cache page corresponding to the target module set can be determined from the cache page of the memory device, and it is used as the target cache page, so that in the subsequent steps, the operating data to be cached can be cached to the target cache page, thereby realizing the classified caching of the operating data.

[0062] S103: writing the running data to be cached into the target cache page, so that the running data in the memory device can be used in units of module sets.

[0063] Specifically, after determining the target cache page, the running data to be cached can be written into the target cache page, thereby realizing the classified caching of the running data. Then, when the running data is used subsequently, it can be directly utilized based on the classified cached running data without classification, which is conducive to improving the use efficiency of the running data.

[0064] The present invention provides a method for storing operation data. Considering that the "operation data generated by a central processing unit" needs to be classified when it is used, the present invention can determine a plurality of cache pages in a memory device. Then, when the operation data is written to the memory device, the operation data can be written to the cache page corresponding to the target module set (the module set to which the functional sub-module to which the operation data to be cached belongs is located). That is, the present invention divides the functional sub-modules in the central processing unit into sets, and independently caches the operation data generated by the functional sub-modules in each module set, so that the operation data in the memory device can be used in units of module sets, eliminating the step of manual classification and improving the convenience of using the operation data and the analysis efficiency.

[0065] Based on the above embodiments:

[0066] As an optional embodiment, determining a cache page corresponding to the target module set from the cache pages of the memory device and using it as the target cache page includes:

[0067] Determine whether there is a cache page that meets a first preset condition in the memory device, wherein the first preset condition is: corresponding to the target module set and having remaining storage space;

[0068] If it does not exist, select a free cache page as the cache page corresponding to the target module set, and use the selected cache page as the target cache page;

[0069] If so, the cache page meeting the first preset condition is used as the target cache page.

[0070] Specifically, in order to more efficiently utilize the existing cache pages, in the embodiment of the present invention, free cache pages can be selected as needed and a corresponding relationship between the selected cache pages and the target module set can be established. That is to say, the target module set may or may not currently have corresponding cache pages. Even if corresponding cache pages exist, it is unknown whether there is remaining storage space. The premise for successfully caching data is that "the target module set has corresponding cache pages and has remaining storage space". Therefore, the embodiment of the present invention pre-sets a first preset condition for the cache page, that is, "corresponding to the target module set and having remaining storage space", and can determine whether there is a cache page that meets the first preset condition in the memory device. If so, it means that there is currently a cache page that can cache data, and the cache page that meets the first preset condition can be used as the target cache page. If not, it means that there is currently no cache page that can cache data. In this case, a free cache page can be selected as the cache page corresponding to the target module set, and the selected cache page can be used as the target cache page, that is, the cache page corresponding to the target module set is expanded.

[0071] Among them, based on the above method of dynamically adding corresponding cache pages, a module set with a large demand for running data cache can use more cache pages, thereby improving the utilization rate of the cache pages.

[0072] As an optional embodiment, determining whether there is a cache page meeting the first preset condition in the memory device includes:

[0073] Obtain the correspondence table between the module set and the cache page from the cache page of the specified sequence number;

[0074] Determine whether there is a cache page corresponding to the target module set in the correspondence table;

[0075] If it exists, determine whether there is remaining storage space in the cache page corresponding to the target module set;

[0076] If not, determining that there is no cache page meeting the first preset condition in the memory device;

[0077] If there is remaining storage space, determining that there is a cache page meeting the first preset condition in the memory device;

[0078] If there is no remaining storage space, determining that there is no cache page meeting the first preset condition in the memory device;

[0079] If not, after selecting an idle cache page as the cache page corresponding to the target module set, the data storage method further includes:

[0080] In the correspondence table, a mapping relationship between the target module set and the newly selected free cache page is added.

[0081] Specifically, in order to efficiently manage the correspondence between module sets and cache pages, in an embodiment of the present invention, a "correspondence table between module sets and cache pages" can be maintained in a cache page of a specified serial number. Then, when determining whether there is a cache page that meets the first preset condition in the memory device, the correspondence table between module sets and cache pages can be first obtained from the cache page of the specified serial number, and then it can be determined whether there is a cache page corresponding to the target module set in the correspondence table. If not, a free cache page can be directly selected. If so, it can be further determined whether there is remaining storage space in the cache page corresponding to the target module set. If not, a free cache page can be directly selected. If so, it can be determined that there is a cache page that meets the first preset condition in the memory device. Since the correspondence changes dynamically, in an embodiment of the present invention, after selecting an idle cache page as the cache page corresponding to the target module set, the mapping relationship between the target module set and the newly selected idle cache page can be added to the correspondence table, that is, the correspondence table is updated in a timely manner.

[0082] The specific form of the correspondence table may be various, for example, a hash table, etc., which is not limited in the embodiment of the present invention.

[0083] As an optional embodiment, selecting an idle cache page as a cache page corresponding to the target module set includes:

[0084] According to each array element in a preset integer array, selecting an idle cache page as a cache page corresponding to the target module set, wherein the array element is used to represent the idle state of each cache page in the corresponding cache page set, and the idle state includes idle and non-idle;

[0085] If not, after selecting an idle cache page as the cache page corresponding to the target module set, the data storage method further includes:

[0086] An array element corresponding to a target cache page set is updated so as to indicate through the array element that the selected idle cache page is in a non-idle state, wherein the target cache page set is: a cache page set where the selected idle cache page is located.

[0087] Specifically, in order to more efficiently maintain the idle state of the cache page, an integer array is used in the embodiment of the present invention to dynamically maintain the idle state of the cache page. The integer array is composed of a number of array elements, and any array element can be used to represent the idle state of each cache page in the corresponding cache page set. Therefore, when selecting an idle cache page, an idle cache page can be selected as the cache page corresponding to the target module set according to each array element in the preset integer array. Accordingly, after selecting an idle cache page as the cache page corresponding to the target module set, the array element corresponding to the target cache page set can be updated so that the array element can represent that the selected idle cache page is in a non-idle state.

[0088] A specific integer array is expressed as: int page_mmap

[256] , where 256 represents the total number of array elements, and a single array element can represent the idle state of each cache page in the corresponding "cache page set including 32 cache pages", with 0 representing the idle state and 1 representing the occupied state (non-idle state). For example, the array element can be expressed as page_mmap[0]= 0x80000001, where 0 represents the serial number of the array element. The serial numbers of the 256 array elements can range from 0 to 255, and the right side of the equal sign is the specific value of the array element. Assuming that the 0th array element corresponds to the idle state of the "cache page set of cache pages with serial numbers 0 to 31", this specific value can indicate that the 0th and 31st cache pages are occupied, and pages 1 to 30 are idle; then by analogy, the second array element represents the idle state of the next group of 32 cache pages..., then assuming page_mmap

[10] = 0x000000FF, that is, the value of the 10th array element is 0x000000FF, which is used to indicate that pages 320 to 327 are occupied, and pages 328 to 351 are idle.

[0089] Of course, in addition to the above method, other methods may be used to “select an idle cache page as the cache page corresponding to the target module set”, which is not limited in the embodiment of the present invention.

[0090] As an optional embodiment, selecting an idle cache page as a cache page corresponding to the target module set, and using the selected cache page as a target cache page includes:

[0091] Determine whether the number of cache pages currently corresponding to the target module set reaches a preset cache page limit of the target module set;

[0092] If not reached, a free cache page is selected as the cache page corresponding to the target module set, and the selected cache page is used as the target cache page;

[0093] If reached, it ends.

[0094] Specifically, considering the importance of the functional sub-modules involved in different module sets and the differences in the amount of running data generated, it is possible to set corresponding cache page limits for different module sets, so as to more efficiently utilize the cache pages in the memory device and control the total amount of running data that can be cached by the module set. Therefore, before selecting a free cache page, the embodiment of the present invention can determine whether the number of cache pages currently corresponding to the target module set has reached the preset cache page limit of the target module set. If it has not reached the limit, it can "select a free cache page as the cache page corresponding to the target module set, and use the selected cache page as the target cache page". If it has reached the limit, it can end, that is, the selection of the free cache page and subsequent operations will not be performed, thereby achieving the purpose of limiting the total number of cache pages that can correspond to the module set.

[0095] The preset cache page limit corresponding to each module set can be independently set and modified, which is not limited in the embodiment of the present invention.

[0096] In addition, considering that if the user does not extract the cached running data for a long time, the cache page may be full, which will cause the cache work to stagnate, and considering that the longer running data generated by the functional sub-modules in some module sets have low utilization value, it is possible to set the validity period of the running data for the specified module set, and periodically check the running data located in the cache page of the specified module set. When the running data in the cache page exceeds the validity period, the expired running data will be automatically cleaned up and the corresponding cache page will be released, so that the released cache page has free cache space.

[0097] As an optional embodiment, each module set includes a single functional sub-module.

[0098] Specifically, in order to classify the operation data in a more detailed manner and to facilitate the use of the operation data, each module set in the embodiment of the present invention includes only a single functional sub-module, that is, each functional sub-module corresponds to its own cache page, that is, the operation data is divided into as many categories for caching as there are functional sub-modules.

[0099] Of course, in addition to this, the module set may also be divided in other forms, which are not limited in the embodiments of the present invention.

[0100] As an optional embodiment, the data processing device is an expansion device of a computer;

[0101] In the memory device, a plurality of cache pages for storing the running data are determined to include:

[0102] Determine, from the memory device of the host computer, a dedicated memory area allocated by the host computer for the expansion device;

[0103] The private memory area is divided into cache pages and numbered.

[0104] To better illustrate the embodiments of the present invention, please refer to Figures 2 to 5 , Figure 2 A schematic diagram of a structure of a running data storage path provided by the present invention, Figure 3 A structural diagram of another operation data storage path provided by the present invention, Figure 4 A schematic diagram of the corresponding relationship between a module set and a cache page provided by the present invention, Figure 5 A schematic diagram of the correspondence between another module set and cache pages provided by the present invention.

[0105] Specifically, in Figure 2 In the process, the operation data generated by the CPU of the expansion device can be directly cached to the cache page in the memory device of the host through the expansion interface and the expansion interface protocol, and then transferred to the hard disk by the host at regular intervals (when transferring to the hard disk, the operation data can also be partitioned and stored in units of module sets for easy distinction and use), without using the memory device, flash memory, peripheral interface and external debugging machine in the expansion device; and Figure 3 In the process, the data processing device (which can also be an expansion device) can cache the operation data through its own memory device, and then one way can be: sending the cached operation data to an external debugging machine through the peripheral interface and the serial port line, and another way is: regularly moving the cached operation data to a non-volatile memory for storage, and the non-volatile memory can be Figure 3 The flash memory in the data processing device may also be a hard disk external to the data processing device, etc., which is not limited in the embodiment of the present invention.

[0106] Specifically, considering that the memory space inside the expansion device of the computer is limited and expensive, if the expansion device supports HMB (Host Memory Buffer, host memory buffer) feature, then the host can allocate a piece of memory from its own memory space for use by the expansion device, thereby reducing the cost of the expansion device and improving the cache efficiency. Therefore, the data processing device in the embodiment of the present invention is an expansion device of the computer, then in the memory device, determining a number of cache pages for storing running data can include: from the memory device of the host of the computer, determining the dedicated memory area allocated by the host to the expansion device. This requires the host to allocate a memory area for the expansion device after identifying that the expansion device supports the HMB feature. The expansion device can obtain the starting address and size of the allocated memory area through communication with the host, and use the memory area as the running data cache area. Then, the running data cache area can be divided into several cache pages. For example, the starting address of the memory area can be 0x20000000, and the size is 32MB. The expansion device can divide the memory area into 8192 cache pages with a cache page size of 4KB and number them, and the number range is 0 to 8191.

[0107] Among them, the HMB feature is used to store the running data in the host memory device, which has higher security. During the hot plugging of expansion devices, the integrity of the running data is ensured and the risk of data loss is avoided.

[0108] Among them, Figure 4 It can be seen that there are a total of 8192 cache pages 0-8191, and the first to Nth module sets correspond to several cache pages. Since the cache page sets corresponding to a single module set are selected and used one by one, the "cache pages corresponding to the module set" can be associated in the corresponding relationship table in the form of a bidirectional linked list. Figure 4 In the figure, each cache page connected by a solid line of a bidirectional arrow corresponds to the same module set, that is, the cache pages numbered 1, 2, 5, and 8 correspond to one module set, and each cache page connected by a dotted line of a bidirectional arrow corresponds to the same module set, that is, the cache pages numbered 3 and 6 correspond to one module set; Figure 4 The cache page No. 0 in is used as the designated cache page for storing the corresponding relationship table. Figure 5 The correspondence between each module set and the cache page is also shown in the form of a hash table. Figure 5In the example, the first module set corresponds to cache pages numbered 1, 2, 5, and 8, the second module set corresponds to cache pages numbered 3 and 6, the third module set corresponds to cache page numbered 4, the fourth module set corresponds to cache pages numbered 7, 11, and 20, and the Nth module set corresponds to cache pages numbered 10, 15, 16, 22, and 23.

[0109] Specifically, the starting address of the memory area, the size of the memory area, and the size of the cache page can all be set independently, and the embodiment of the present invention does not limit this.

[0110] The expansion device may be of various types, such as a RAID (Redundant Array of Independent Disks) card, etc., which is not limited in the embodiment of the present invention.
