Terminal resource management system for multi-application process embedded system and method

Abstract

The invention provides a terminal resource management system for a multi-application process embedded system and a method. All application processes need to call specific application program interfaces to access terminal resources; the terminal resources are a set of capabilities provided by a terminal hardware platform and comprise a CPU (Central Processing Unit), a memory, a hard disk, a decoder, a demultiplexer, a graphic engine, and the like; when a plurality of applications are simultaneously operated, dynamic priorities for the application processes are set up according to the types of the applications and a statistical regularity that users use the applications; when some kind of terminal resources is overloaded or is in a conflict because more applications are operated in a system, the terminal resources are optimally allocated and dispatched by combining an application process status control method and the priorities so as to preferably ensure the reliable operation of applications with high priorities. The terminal resource management system for the multi-application process embedded system and the method have the advantages that: the controllability and the safety for accessing shared terminal resources are improved; and the terminal resource management based on user experience is achieved, the reliable and efficient operation of applications which users pay more attention to can be preferably guaranteed so as to improve the user experience.

Description

technical field [0001] The present invention relates to an embedded system multi-application support technology, mainly to implement an application process-oriented embedded system terminal resource management method under the scenario of supporting multiple applications running simultaneously, and specifically relates to a multi-application process embedded system terminal resource management system and method. Background technique [0002] Terminal resource management is an important part of embedded systems. Terminal resource management provides access methods for terminal resources, such as CPU, memory, network bandwidth, decoder, demultiplexing channel, graphics, etc., for each application program running on the embedded system. In an environment where multiple applications are running at the same time, the limited embedded system terminal resources are prone to certain terminal resource overload, or due to the mutual exclusion of shared terminal resources such as deco...
