Problems solved by technology

like figure 1 As shown, when process A and process B are actually running, the time of data access is interleaved, so in fact, when accessing data in the memory, the continuous action of the address will be easily broken, resulting in a time delay during data access. waste

Abstract

The invention discloses a method and device for dynamically allocating a physical address and an electronic device. The method comprises the following steps: detecting whether an event of dynamicallyallocating a physical address of data accessed by an application program occurs; According to the detection results of events, the time order of accessing data in the process of application program running is obtained; Obtaining a logical address of the data stored in advance in the application program according to the detection result of the event; According to the time order and logical addressof the data, the physical address is assigned to the data so that the physical address of the data corresponds to the time order. As such, that proportion of time the system spend accessing the storage as a contiguous physical address increase during the running of the application, thereby increasing the efficiency of the system storage access to the storage.

Description

technical field [0001] The present invention relates to the technical field of physical address allocation, and more specifically, the present invention relates to a method, device and electronic equipment for dynamically allocating physical addresses. Background technique [0002] At present, traditional storage (such as memory, flash memory) is usually accessed after the software code is compiled, and the data access address is usually fixed. For example, writing and reading of DRAM (memory) or Flash (flash memory). The way to determine the access address is usually closely related to code programming, but the design of the memory is usually the most efficient when the address is continuous, so the ratio of access data in the address continuous (burst mode) when the program is running has a significant impact on memory access performance. [0003] In the traditional approach, when the program is executed, the spatial arrangement of data access on the physical address is c...
