Abstract

The invention discloses a method, a device, equipment and a medium for optimizing the starting speed of a vehicle-mounted system and an application, wherein the method comprises triggering pre-reading service according to system events of different sub-stages in the system starting stage, and loading the resource files corresponding to different sub-stages into a cache in an asynchronous loading mode, and in an application starting stage, responding to clicking operation of a user on a target application icon, and starting a main process of the target application while asynchronously triggering the pre-reading service to load the installation package resources of the target application. In the system starting stage, resources are preloaded into a memory cache through segmented triggering of a pre-reading service, so that the problem that a subsequent process is blocked due to synchronous IO waiting when the resources are needed is avoided, and IO bandwidth saturation caused by traditional one-time preloading is avoided through segmented preloading. When a user clicks an application icon, the application related resources are preloaded through asynchronous triggering of the pre-reading service, and the situation that the application is blocked to start a main thread in the preloading process is avoided.

Description

Method, device, equipment and medium for optimizing starting speed of vehicle-mounted system and application Technical Field The present invention relates to the field of vehicle technologies, and in particular, to a method, an apparatus, a device, and a medium for optimizing a starting speed of a vehicle-mounted system and an application. Background The starting speed of the vehicle-mounted system is one of key indexes affecting the user experience. In vehicle-mounted system development, optimization of the start-up process has become an important issue. The traditional starting optimization method mainly reduces the initialization load by cutting unnecessary system services and other components, thereby shortening the starting time. However, with the increasing richness and complexity of the functions of the vehicle-mounted system, the optimization mode simply relying on component clipping approaches the performance bottleneck, and further significant reduction of the starting time is difficult to achieve. This problem is particularly pronounced on low-power hardware platforms. Taking a platform with a full-lineage T527 application processor and running an Android 13 system as an example, a significant gap exists between computing resources and high-end mobile devices. On such a platform, the system starting process faces multiple challenges, namely, firstly, the CPU computing power is limited, a plurality of system services and application processes are started concurrently to cause intense CPU resource competition, secondly, memory resources are tense, frequent memory allocation requests in the starting stage are easy to cause conflict, furthermore, input/output (IO) resources become key bottlenecks, a large amount of data are required to be loaded from storage equipment when the system is started, and the traditional IO scheduling and management mechanism is difficult to process high-concurrency reading requests efficiently, and system blocking is easy to cause. After the system is started due to the comprehensive effect of the resource bottleneck, even if a user interface is presented, the underlying service and the application program still can not be ready due to resource contention, so that the system can not respond to user operation in time temporarily, and the user experience is seriously affected.
