Embodiment Construction

[0022] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0023] like Figures 1a-1d As shown, firstly introduce various thread synchronization methods, among the various operations of a program, often only part of the order is required, there are both parallel execution parts and serial execution parts. In this embodiment, the situation of using UML technology to design a synchronous timing relationship for a multi-threaded software is shown. In the figure, 'S' and 'F' represent the start and end respectively, and P1-P7 represent each thread.

[0024] UML activity diagrams can contain forking control of concurrent threads. Concurrent threads represent activities that can be performed concurrently by different objects and people in the system. Usually concurrency originates from aggregation, where each object has its own thread, and these th...

Abstract

The invention discloses a multi-thread software concurrent design method, which comprises the following steps of: 1, designing a user interface (UI) lane, a downloading thread lane and a java virtual machine thread lane; 2, downloading a java application program in the downloading thread lane through a browser, and transmitting a uniform resource locator (URL) of a java archive (JAR) to the browser in the java virtual machine thread lane in a call-back mode; and 3, downloading the JAR in the downloading thread lane by using the browser, and calling a third party asynchronous interface to install the java application program after the JAR is downloaded. In the software concurrent design method, threads are divided into different lanes, and steps which are needed to be executed in the lanes are designed in the lanes, so that synchronization and mutex relationships among the threads can be comprehensively designed; and severe phenomena such as crash, black screen, fixed screen, restart and the like due to improper processing are avoided.

Description

technical field [0001] The invention relates to a multi-thread software concurrent design method, in particular to a multi-thread software concurrent design method based on UML technology. Background technique [0002] In the prior art, there are many software platforms supporting multithreading, such as Datang ARENA, and there are complex synchronization and mutual exclusion relationships between software based on this platform. The high-level business software part of the mobile phone also interacts more with the network, and network programming generally adopts four calling methods: asynchronous, synchronous, blocking, and non-blocking. At the same time, the platform notifies the upper layer software of various interruptions in the form of channel messages, such as closing the cover, rotating the screen, PUSH messages, alarm clocks, etc. [0003] High-level business software such as WAP, MMS, JAVA, and streaming media mostly use LIB libraries provided by third parties. T...
