Problems solved by technology

Since the electronic map itself occupies a large amount of memory, it will generate a high CPU (central processing unit) occupancy rate when rendering the map, consuming a lot of CPU resources, which will cause the system to freeze

Abstract

The invention relates to a resource allocation method and device of a map engine and electronic equipment. The method comprises the steps that a specified event is detected, wherein a preset number offrames and preset time for rendering are pre-allocated to the specified event; rendering is carried out according to the specified event, and if the number of frames run by the CPU is greater than the allocated preset number of frames and / or the running time is greater than the allocated preset time, the number of frames run by the CPU is reduced to a preset lowest number of frames. According tothe method, the preset number of frames and the preset time for rendering are allocated in advance for the specified event, so that the CPU performs rendering according to the preset number of framesand the preset time. In this way, on one hand, the running frame number of the CPU is controlled, and the situation that too many CPU resources are occupied due to the too large frame number is avoided; and on the other hand, the rendering duration is controlled, and the situation that CPU resources are continuously occupied due to long-time rendering is avoided.

Description

technical field [0001] The present application relates to the field of navigation technology, and in particular to a resource allocation method, device and electronic equipment of a map engine. Background technique [0002] The electronic map brings great convenience to people's life. The electronic map is installed on the terminal. By viewing the electronic map, it is convenient for the user to know the geographical location, plan the route, and navigate. The user can control the electronic map on the terminal through gesture operations such as sliding or zooming, and the electronic map displays map data on the terminal screen according to the instruction. [0003] When events such as user position changes, dragging the interface, or changing the zoom ratio of the map occur, the range of the electronic map displayed on the screen also changes, and the electronic map needs to be reloaded and rendered. Since the electronic map itself occupies a large amount of memory, it wil...
