[0002] With the continuous development of Internet technology and display technology, people have higher and higher requirements for display scenes such as games, animations, and virtual worlds. In particular, for display objects such as special effects, the elements that need to be displayed are many and complex, and the display processing is even more complicated.

[0003] In current technology, developers often use a processing system that includes multiple display units to perform display processing on the above-mentioned complex display objects. By configuring multiple display units in the processing system, such as an emission display unit, a shape display unit, a color display unit, a collision display unit, etc., each display unit can be individually configured with display parameters, and the display of a display object can be achieved based on the display parameters configured by multiple display units.

[0004] However, since each display unit of the processing system is configured with specific display parameters, this will cause the processing system to occupy a high memory consumption. When it is necessary to display complex display objects in a large scene, many different processing systems will be called.

[0023] In addition, it should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in one or more embodiments of this specification are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0024] First, the terms involved in one or more embodiments of this specification are explained.

[0025] Display unit: A display unit is an independent module or component used in modern display technology to handle specific types of display tasks, such as particle emission, shape drawing, color rendering, and collision detection. Each unit can be configured with display parameters independently and work together to achieve complex visual effects.

[0026] Memory Move: Memory Move refers to the operation of copying or moving data from one memory location to another. This operation is very common in computer programming, especially when it is necessary to reorganize the data structure in memory or migrate data.

[0027] Memory reallocation: Memory reallocation refers to changing the size or location of allocated memory to better meet current needs.

[0028] In this specification, a memory allocation method is provided. This specification also relates to a memory allocation device, a computing device, a computer-readable storage medium, and a computer program product, which are described in detail one by one in the following embodiments.

[0029] See also Figure 1 , Figure 1 A flowchart of a memory allocation method provided according to an embodiment of the present specification is shown, which specifically includes the following steps.

[0030] Step 102: Store the display parameters of each display unit to be used into the global memory, and set the state of each display unit to be in a ready-to-use state.

[0031] The memory allocation method provided in the embodiments of this specification can be applied to various applications, websites or applets, including but not limited to: Unity development engine, 3DS Max development engine, Unreal Engine development engine, Maya development engine, Blender development engine, etc. Specifically, it can be executed by a personal computer (PC), a workstation, a game console, a personal mobile device, a server, etc., and this specification does not make specific limitations on this. Exemplarily, the memory allocation method provided in the embodiments of this specification can be applied to the Unity development engine running on a personal computer.

[0032] A display unit refers to a small software module or component in a processing system that is used to handle specific types of display tasks. Different display units can perform different display functions and achieve different display effects. For example, a speed display unit can display the moving speed of a target object that needs to be displayed. The display parameters of a display unit refer to the specific configuration parameter values ​​that control the appearance and behavior of the display unit. For example, the display parameters of a speed display unit can be 500m / s, indicating that the moving speed of the target object that needs to be displayed is 500m / s. Global memory is a piece of memory allocated in the operating system that can be read by multiple different processing systems to read the display parameters of each display unit. The pending state means that the current display unit is not called by the processing system.

[0033] For example, Figure 2 FIG. 4 shows a schematic diagram of a global shared memory construction in a memory allocation method provided in an embodiment of the present specification. Figure 2As shown: the global memory stores display parameters of the emission display unit, size display unit, shape display unit, speed display unit, color display unit, and trailing display unit, and the state of each display unit is in a standby state. The display parameters stored in the global memory are the initial parameters of the display unit. When the display unit is in a standby state, it is not called by the processing system, so its initial parameters are determined and unchanged values.

[0034] In the embodiments of the present specification, by storing the display parameters of each display unit to be used in the global memory and setting the state of each display unit to be used, the display parameters of each display unit can be uniformly managed, the access operation can be simplified, the memory copy can be reduced, and the data transmission efficiency can be improved, thereby improving the overall performance and data consistency.

[0035] Step 104: Initialize the target processing system and determine the first display unit in the target processing system that is in use.

[0036] The processing system is an architecture for managing the display unit and its display parameters. Different processing systems can be selected according to different usage scenarios or application fields, such as graphics rendering system, audio processing system, network communication system, particle system, etc. This specification does not make specific limitations on this. For example, the processing system can be a particle system (Particle System), and the display unit can include an emission display unit, a size display unit, a shape display unit, a speed display unit, a color display unit, and a trailing display unit, etc. This specification does not make specific limitations on this.

[0037] Initializing the target processing system refers to the process of setting various parameters of the target processing system before it starts running. Specifically, the reference for initialization can be preset by the user in advance or calculated by the current application. The initialization process can include creating a processing object of the target processing system, setting the initial display parameters and status of each display unit in the target processing system, etc. Exemplarily, the A particle system is initialized, and according to the display units and display parameters included in the display units that should be used in the A particle system preset by the user in advance, the emission display unit, color display unit, and size display unit included in the A particle system are set to be in use, and the shape display unit, speed display unit, and trailing display unit are set to be in a ready-to-use state, and the initial display parameters of each display unit are configured.

[0038] After the target processing system is initialized, the display unit in use is determined as the first display unit according to the states of the set display units.

[0039] In the embodiments of the present specification, the target processing system is initialized, the initial parameters and status of each display unit are set, and the display unit in use is determined to be the first display unit, thereby ensuring that the target processing system operates according to the predetermined configuration from the beginning. At the same time, the display units actually used by the target processing system can be determined, avoiding processing of unused display units, thereby improving the processing efficiency of the target processing system.

[0040] Step 106: extract the display parameters of the first display unit from the global memory and store them in the local memory corresponding to the target processing system.

[0041] The local memory is a piece of memory allocated to each processing system in the memory space, and is used to store display parameters of the display unit of each usage state of the processing system.

[0042] After determining the first display unit in use in the target processing system, various display parameters corresponding to the first display unit are extracted from the global memory, and the display parameters are stored in the local memory corresponding to the target processing system.

[0043] Exemplarily, it is determined that the first display unit in use in the A particle system is an emission display unit, a color display unit, and a size display unit, then the display parameters of these three display units are extracted from the global memory and stored in the local memory corresponding to the A particle system for the A particle system to call during processing.

[0044] In the embodiment of the present specification, by extracting the display parameters of the first display unit in use from the global memory and storing them in the local memory corresponding to the target processing system, it is ensured that the target processing system can quickly and efficiently access and use the display parameters of each display unit in use, thereby optimizing the overall performance and response speed.

[0045] In an optional embodiment of the present specification, after step 104, the following specific steps are also included: Determine a second display unit in the target processing system that is in a ready-to-use state; The pointer of the first display unit points to the local memory, and the pointer of the second display unit points to the global memory.

[0046] The pointer of each display unit in the processing system will point to the specific memory address block in the memory where the display parameters of each display unit are stored. After determining the first display unit in use and the second display unit in the waiting state, for the first display unit, since its display parameters will be extracted from the global memory and stored in the memory address block of the local memory corresponding to the processing system, the pointer of the first display unit is set to point to the memory address block of the local memory. For the second display unit, its display parameters are not extracted from the global memory, so the pointer of the second display unit is set to point to the memory address block of the global memory.

[0047] For example, Figure 3 FIG. 1 shows a schematic diagram of memory after the processing system is optimized in a memory allocation method provided in one embodiment of the present specification, such as Figure 3 As shown: the display parameters of the emission display unit, color display unit, and size display unit in use are stored in the local memory, and their pointers point to themselves (not shown by arrows in the figure); while the display parameters of the shape display unit, speed display unit, and trailing display unit in the waiting state are stored in the global memory, so their pointers point to the display parameters stored in the corresponding display units in the global memory.

[0048] In the embodiment of the present specification, by pointing the pointer of the first display unit in use to the local memory and the pointer of the second display unit in the to-be-used state to the global memory, it can be ensured that the target processing system can quickly access the display parameters of the display unit currently in use, thereby improving processing efficiency. At the same time, the parameters of the to-be-used unit are retained in the global memory for rapid switching during subsequent use, thereby optimizing overall performance and resource utilization.

[0049] In an optional embodiment of the present specification, step 106 includes the following specific steps: Extracting display parameters of the first display unit from the global memory; Determining a first target memory in a local memory corresponding to the target processing system based on a memory size occupied by display parameters of the first display unit; The display parameters of the first display unit are stored in the first target memory.

[0050] After the display parameters of the first display unit are extracted from the global memory, the size of the memory space occupied by the display parameters of the first display unit is counted, and then a first target memory of the same size is determined in the local memory of the target processing system, and the display parameters of the first display unit are stored in the first target memory. Preferably, the first target memory is a continuous memory, and the display parameters of the first display unit are continuously stored in the first target memory.

[0051] Exemplarily, taking the aforementioned particle system A as an example, after extracting the display parameters of the emission display unit, color display unit, and size display unit belonging to the first display unit from the global memory, the size of the memory space occupied by these display parameters is counted, and then in the local memory corresponding to the particle system A, a continuous and same-size memory is determined as the first target memory, and then the emission display unit display parameters, color display unit display parameters, and size display unit display parameters are continuously stored in the first target memory.

[0052] In the embodiments of the present specification, by extracting the display parameters of the first display unit from the global memory and allocating a first target memory of the same size in the local memory of the target processing system, and continuously storing the display parameters in this continuous memory, the data access speed and processing efficiency can be significantly improved, memory fragmentation can be reduced, and data integrity and continuity can be ensured, thereby optimizing the performance and response speed of the system.

[0053] In an optional embodiment of the present specification, after step 106, the following specific steps are also included: When receiving the state switching instruction, switching the state of the third display unit indicated by the state switching instruction in the target processing system; Based on the state of the third display unit, the display parameters of the third display unit are stored in the local memory corresponding to the target processing system.

[0054] After the display parameters of the first display unit are stored in the local memory, the target processing system starts the processing operation. When the application needs to display the display effect of the new target object during the processing, the state of each display unit in the target processing system will be switched as required, thereby generating a state switching instruction to instruct one or more display units in the target processing system to switch the state, and the display unit that needs to switch the state is the third display unit.

[0055] Based on the state of the third display unit after switching, the display parameters of the third display unit are stored in the local memory of the target processing system. The storage process includes storing the display parameters of the third display unit and deleting the display parameters of the third display. In actual applications, after the state switching of the third display unit is completed, for the display parameters of the third display unit, an independent memory can be reallocated in the local memory of the processing system for storage operations; or the storage operation can be performed after the memory corresponding to the first display unit that has been allocated previously; or the previously allocated memory can be released and a continuous memory can be reallocated for storage operations. This specification does not make specific limitations on this.

[0056] In the embodiments of the present specification, when a state switching instruction is received, the state of the third display unit in the target processing system is switched, and the corresponding display parameters are stored or deleted in the local memory according to the switched state. In this way, the state and parameters of the display unit can be dynamically adjusted, the flexibility and response speed of the system can be improved, and resource allocation in the processing process can be ensured to be more efficient and timely.

[0057] In an optional embodiment of the present specification, based on the state of the third display unit, the display parameters of the third display unit are stored in the local memory corresponding to the target processing system, including the following specific steps: Based on the state of the third display unit, determining a fourth display unit in the target processing system that is in use after the state switching; The display parameters of the fourth display unit are stored in a local memory corresponding to the target processing system.

[0058] After the state switching of the third display unit is completed, the display unit in the target processing system that is in use is re-determined as the fourth display unit. Specifically, the third display unit that has completed the state switching can be directly used as the fourth display unit; the third display unit that is in use after the state switching is completed and the first display unit that was originally in use can also be used together as the fourth display unit; the other display units of the first display unit that was originally in use, except for the third display unit that is in a waiting state due to the state switching, can also be used as the fourth display unit. After the fourth display unit is determined, the display parameters of the fourth display unit can be stored in the local memory corresponding to the target processing system.

[0059] In the embodiment of the present specification, after completing the state switching of the third display unit, the fourth display unit in use is re-determined, and its display parameters are stored in the local memory corresponding to the target processing system. This ensures that the display unit currently in use can quickly access its parameters, improves processing efficiency, and optimizes memory usage to ensure smooth system operation and quick response.

[0060] In an optional embodiment of the present specification, the state switching instruction is an on instruction; the fourth display unit includes a first display unit and a third display unit; and the state of the third display unit indicated by the state switching instruction in the target processing system is switched, including the following specific steps: Switching the state of the third display unit indicated by the start instruction in the target processing system to a use state; Storing the display parameters of the fourth display unit into a local memory corresponding to the target processing system includes: Extracting display parameters of the third display unit from the global memory, and extracting display parameters of the first display unit from the local memory; The display parameters of the third display unit and the display parameters of the first display unit are stored in a local memory corresponding to the target processing system.

[0061] When the state switching instruction is an on instruction, it indicates that the target processing system needs to dynamically enable the second display unit which is in the standby state, and switches the state of the second display unit from the standby state to the use state according to the state switching instruction. At this time, the switched display unit is used as the third display unit, and the fourth display unit includes the first display unit and the third display unit.

[0062] When storing the display parameters of the fourth display unit into the local memory corresponding to the target processing system, since the display parameters of the first display unit have been extracted from the global memory and stored in the local memory after initialization, it is only necessary to extract the display parameters of the third display unit from the global memory and extract the display parameters of the first display unit from the local memory. Then, the display parameters of the fourth display unit are stored into the local memory corresponding to the target processing system.

[0063] For example, Figure 4 FIG. 1 shows a schematic diagram of a target memory of an open instruction in a memory allocation method provided by an embodiment of the present specification, such as Figure 4 As shown: before the state switching, the display parameters of the emission display unit, color display unit, and size display unit in the target processing system that are in use are stored in the local memory, and the display parameters of the shape display unit, speed display unit, and trailing display unit that are in the waiting state are stored in the global memory. When the state switching instruction is an on instruction and the indicated display unit is the speed display unit, the state of the speed display unit in the target processing system is switched from the waiting state to the used state, and the display parameters corresponding to the speed display unit are extracted from the global memory and stored at the end of the display parameters of the display unit in the used state that have been stored in the local memory of the target processing system, and memory reallocation (Reallocate) is used to expand the memory allocation, and then the pointers of each display unit in the target processing system are updated.

[0064] In the embodiment of the present specification, after receiving the start-up command, the state of the third display unit is switched to the use state, and its display parameters are stored in the local memory together with the display parameters of the first display unit already in the local memory. This ensures that all currently used display units can efficiently access the display parameters, improves the processing speed and response efficiency of the system, and optimizes memory usage, making the system run more smoothly.

[0065] In an optional embodiment of the present specification, the state switching instruction is a closing instruction; and the state of the third display unit indicated by the state switching instruction in the target processing system is switched, further comprising the following specific steps: The state of the third display unit indicated by the shutdown instruction in the target processing system is switched to a standby state.

[0066] In the case where the state switching instruction is a closing instruction, it means that the target processing system needs to dynamically close the first display unit in the use state. At this time, the third display unit is the display unit to be dynamically closed, and the fourth display unit includes the display units in the first display unit except the third display unit. After determining the fourth display unit, the display parameters corresponding to the fourth display unit can be obtained and stored in the local memory of the target processing system. Specifically, because the fourth display unit is the display unit in the first display unit except the third display unit, it has been set to the use state when the target processing system is initialized, so its corresponding display parameters have been stored in the memory address block previously allocated in the local memory of the target processing system. At this time, it is only necessary to obtain the display parameters from the previously allocated memory address block, and then reallocate a new memory address block for storage according to the size of the memory space occupied by the display parameters.

[0067] For example, Figure 5 FIG. 1 shows a schematic diagram of a target memory of a close instruction in a memory allocation method provided by an embodiment of the present specification, such as Figure 5 As shown: before the state switching, the display parameters of the emission display unit, color display unit, and size display unit in the target processing system that are in use are stored in the local memory, and the display parameters of the shape display unit, speed display unit, and trailing display unit that are in the waiting state are stored in the global memory. When the state switching instruction is a closing instruction and the indicated display unit is a color display unit, the state of the color display unit in the target processing system is switched from the use state to the waiting state, and its corresponding display parameters are deleted from the local memory of the target processing system, and the display parameters of the subsequent size display units are moved forward to cover the memory of the display parameters of the original color display unit by using memory move, and the memory space occupied by the display parameters of the emission display unit and the size display unit in the open state is recalculated, and memory reallocation is used to reduce the memory allocation, and then the pointers of each display unit in the target processing system are updated.

[0068] In an embodiment of the present specification, after receiving a shutdown command, the state of the third display unit is switched to a standby state, and its display parameters are removed from the local memory, while the display parameters of other display units that are still in use are retained in the local memory. This can release memory resources that are no longer in use, optimize memory usage, improve system efficiency and response speed, and ensure that resource allocation is more reasonable and efficient.

[0069] The following combination Figure 6 , taking the application of the memory allocation method provided in this specification in the game development scenario as an example, the memory allocation method is further explained. Figure 6 A processing flow chart of a memory allocation method applied to a game development scenario provided by an embodiment of the present specification is shown, which specifically includes the following steps.

[0070] Step 602: construct a globally shared memory containing display parameters of all modules, and set all modules to a closed state. The global memory block will serve as the default memory space for unused modules; Step 604: Initialize the particle system, count the modules actually used by the particle system, calculate the memory size occupied by the display parameters of the modules used in the particle system, and apply for a continuous memory according to the occupied memory size, allocate it to the modules actually used in the particle system, and set the pointers of other unused modules in the particle system to point to the memory address blocks in the global shared memory; Step 606: when a module needs to be dynamically enabled, the dynamically enabled module is merged into the end of the enabled modules, the memory size occupied by the display parameters of the modules used in the particle system is recalculated, and according to the occupied memory size, new memory is reallocated for storage using memory reallocation technology, and the used module pointer is pointed to the newly allocated memory; Step 608: When it is necessary to dynamically close a module, the memory movement technology is used to move the module behind the deleted module forward to overwrite the memory of the dynamically closed module, and the memory size occupied by the display parameters of the module used in the particle system is recalculated. Based on the occupied memory size, the memory reallocation technology is used to reallocate new memory for storage, and the used module pointer is pointed to the newly allocated memory.

[0071] In the embodiments of the present specification, efficient memory utilization and fast state switching are achieved by constructing a global shared memory and dynamically managing the display parameters of the modules in the particle system. Specifically, unused module parameters are stored in the global memory, and continuous memory is allocated to the modules actually used, thereby reducing memory fragmentation and improving memory access efficiency. When it is necessary to dynamically open and close the module, the continuity and compactness of the memory are ensured through memory reallocation and movement technology, further optimizing memory usage and improving the response speed and overall performance of the system.

[0072] Corresponding to the above method embodiment, this specification also provides a memory allocation device embodiment, Figure 7 FIG. 2 shows a schematic diagram of the structure of a memory allocation device provided by an embodiment of the present specification.
