Obviously, the embodiments described are only 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 making creative efforts should fall within the scope of protection of the present invention.

[0036] The terms "first," "second," and "third," etc., in the specification and claims of the present invention and the accompanying drawings are used to distinguish between different objects, not to describe a specific order. Furthermore, the terms "comprise," "comprising," and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or modules is not limited to the listed steps or modules, but may optionally include steps or modules not listed, or may optionally include other steps or modules inherent to the process, method, product, or apparatus.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0038] The specific implementation of the data read / write processing method of the present invention is described below with reference to the accompanying drawings.

[0039] In at least one embodiment of the present invention, the data read / write processing method is applied to a data read / write processing device 100 (eg Figure 2 The data read / write processing method specifically includes the following steps. According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted.

[0040] Step S10: receiving a data read / write request.

[0041] In at least one embodiment of the present invention, the data read and write request may include a command type, data, address, resource identifier, and priority. In at least one embodiment of the present invention, the data read and write request may be executed by the processor 106 (e.g., Figure 2 shown) is produced.

[0042] Step S11, determining whether the data read / write request is a read request.

[0043] Step S12: When the data read / write request is a read request, determine whether the data read / write request satisfies a first placement rule.

[0044] In at least one embodiment of the present invention, the first placement rule is that the address corresponding to the data read / write request does not conflict with the address corresponding to the write request in the write command queue.

[0045] Step S13: When the data read / write request does not satisfy the first placement rule, directly read the data corresponding to the write request with the address conflict.

[0046] Step S14: When the data read / write request satisfies the first placement rule, determine whether the data read / write request satisfies the second placement rule.

[0047] In at least one embodiment of the present invention, the second placement rule is that the resource identifier corresponding to the data read / write request does not conflict with the resource identifier corresponding to the write request in the write command queue.

[0048] Step S15 : When the data read / write request does not satisfy the second placement rule, the data read / write request is stored in the read command queue according to the reception time.

[0049] Step S16: When the data read / write request satisfies the second placement rule, insert the data read / write request into the read command queue according to a third placement rule.

[0050] In at least one embodiment of the present invention, the third placement rule is to insert the data read / write request into the read command queue according to the priority level corresponding to the data read / write request.

[0051] Step S17: When the data read / write request is a write request, determine whether the data read / write request satisfies a fourth placement rule.

[0052] In at least one embodiment of the present invention, the fourth placement rule is that the address and resource identifier corresponding to the data read and write request do not conflict with the address or resource identifier corresponding to any read request in the read command queue.

[0053] Step S18: When the data read / write request does not satisfy the fourth placement rule, the data read / write request is stored in the write command queue according to the reception time.

[0054] Step S19: When the data read / write request satisfies the fourth placement rule, insert the data read / write request into the write command queue according to the fifth placement rule.

[0055] In at least one embodiment of the present invention, the fifth placement rule is to insert the data read / write request into the current write command queue according to the priority level corresponding to the data read / write request.

[0056] The above-mentioned data read / write processing method compares the address corresponding to the read request with the address corresponding to the write request in the write command queue, and directly obtains the corresponding data from the write command queue in the event of a conflict, thereby reducing the delay of the read operation and maintaining data consistency. At the same time, the processing efficiency of data read and write requests is optimized by detecting address conflicts, resource identification conflicts, data conflicts, etc. In addition, the enabling and disabling of multiple placement rules can be set according to needs to achieve flexible adjustment of placement rules. When the second placement rule is effective, when multiple read or write requests access the same address, they are sorted according to the reception time, and the order will not be adjusted due to priority, thereby ensuring data integrity.

[0057] Please also refer to Figure 2 and Figure 3 , Figure 2 The present invention provides an architecture diagram of a data read / write processing device 100. Figure 3This is a block diagram of a data read / write processing system 10 provided by the present invention.

For example, the data read / write processing device 100 can be a mobile device such as a personal computer, tablet computer, smart phone, personal digital assistant (PDA), game console, interactive network television (Internet Protocol Television, IPTV), smart wearable device, navigation device, etc., or a fixed device such as a desktop computer, digital TV, etc. The data read / write processing device 100 includes a memory 102, a communication bus 104, and a processor 106.

[0058] The memory 102 is used to store program code. The memory 102 can be a circuit with a storage function that does not have a physical form in an integrated circuit, such as a memory stick, a TF card (Trans-flash Card), a smart media card (smart media card), a secure digital card (secure digital card), a flash memory card (flash card) and other storage devices. The memory 102 can communicate data with the processor 106 via a communication bus 104. The memory 102 may include an operating system and a data read / write processing system 10. The operating system is a program that manages and controls the hardware and software resources of the data read / write processing device 100, and supports the operation of the data read / write processing system and other software and / or programs.

[0059] The processor 106 may include one or more microprocessors or digital processors. The processor 106 may call the program code stored in the memory 102 to execute related functions. For example, Figure 2 Each module described is a program code stored in the memory 102 and executed by the processor 106 to implement a data read / write processing method. The processor 106, also known as the central processing unit (CPU), is a large-scale integrated circuit that serves as both the computing core and the control unit.

[0060] In at least one embodiment of the present invention, the data read / write processing system 10 includes one or more modules, and the one or more modules are executed by at least one or more processors 106 to implement data read / write processing functions.

[0061] In at least one embodiment of the present invention, the data read / write processing system 10 includes:

[0062] The receiving module 12 is configured to receive a data read / write request.

[0063] In at least one embodiment of the present invention, the data read / write request may include a command type, data, address, resource identifier, and priority. In at least one embodiment of the present invention, the data read / write request may be generated by the processor 106 .

[0064] The judgment module 14 is configured to judge whether the data read / write request is a read request. If the data read / write request is a read request, the judgment module 14 further judges whether the data read / write request satisfies a first placement rule.

[0065] In at least one embodiment of the present invention, the first placement rule is that the address corresponding to the data read / write request does not conflict with the address corresponding to the write request in the write command queue.

[0066] The acquisition module 16 is configured to directly read data corresponding to the write request with the address conflict when the data read / write request does not satisfy the first placement rule.

[0067] When the data read / write request satisfies the first placement rule, it is determined whether the data read / write request satisfies a second placement rule.

[0068] In at least one embodiment of the present invention, the second placement rule is that the resource identifier corresponding to the data read / write request does not conflict with the resource identifier corresponding to the write request in the write command queue.

[0069] The insertion module 18 is configured to store the data read / write request in the read command queue according to a reception time when the data read / write request does not satisfy the second placement rule. If the data read / write request satisfies the second placement rule, the insertion module 18 further inserts the data read / write request into the read command queue according to a third placement rule.

[0070] In at least one embodiment of the present invention, the third placement rule is to insert the data read / write request into the read command queue according to the priority level corresponding to the data read / write request.

[0071] When the data read / write request is a write request, the determination module 14 further determines whether the data read / write request satisfies a fourth placement rule.

[0072] In at least one embodiment of the present invention, the fourth placement rule is that the address and resource identifier corresponding to the data read and write request do not conflict with the address or resource identifier corresponding to any read request in the read command queue.

[0073] When the data read / write request does not satisfy the fourth placement rule, the insertion module 18 further stores the data read / write request in the write command queue according to the reception time.

[0074] When the data read / write request satisfies the fourth placement rule, the insertion module 18 further inserts the data read / write request into the write command queue according to a fifth placement rule.

[0075] In at least one embodiment of the present invention, the fifth placement rule is to insert the data read / write request into the current write command queue according to the priority level corresponding to the data read / write request.

[0076] The above-mentioned data read / write processing device 100 compares the address corresponding to the read request with the address corresponding to the write request in the write command queue, and directly obtains the corresponding data from the write command queue when there is a conflict, thereby reducing the delay of the read operation and maintaining data consistency. At the same time, the processing efficiency of data read and write requests is optimized by detecting address conflicts, resource identification conflicts, data conflicts, etc. In addition, the enabling and disabling of multiple placement rules can be set according to needs to achieve flexible adjustment of placement rules. When the second placement rule is effective, when multiple read or write requests access the same address, they are sorted according to the reception time, and the order will not be adjusted due to priority, thereby ensuring data integrity.

[0077] The present invention also provides a storage medium. The storage medium is a computer-readable storage medium. The computer-readable storage medium stores computer instructions. The computer instructions can be stored in the memory 102, and when executed by one or more processors 106, the data reading / writing processing method based on the high-precision map as described in the above method embodiment is implemented, for example Figure 1 S10-S19 shown are not repeated here.
