Policy mode based multi-thread management method for signal generator

Abstract

The invention proposes a policy mode based multi-thread management method for a signal generator. According to the method, thread management modules are divided into a signal source thread base class, functional thread derived classes and a thread management class, wherein the signal source thread base class is in charge of defining and maintaining basic information of threads and establishing a thread processing framework; the functional thread derived classes inherit from the signal source thread base class and are in charge of specifically realizing specific functions, and each specific function corresponds to a functional thread derived class; and the thread management class is in charge of defining and maintaining objects of the functional thread derived classes, distributing index numbers to the threads, and providing corresponding thread management interfaces for external users of the thread management modules through unique and global thread management class objects. According to the method, the development efficiency of software research and development is improved, the development cost is reduced, the consistency of the threads in use is improved, the extendibility of the functions and the security and reliability of synchronism and mutual exclusion relationships among the threads are enhanced, and rich thread debugging information supports full-life-cycle thread monitoring.

Description

technical field [0001] The invention relates to the application field of computer software, in particular to a multi-thread management method of a signal generator based on a strategy mode. Background technique [0002] With the development of computer technology, signal generators have more and more functions, the relationship between functions is more and more complex, the user experience fluency requirements are getting higher and higher, and the number of threads used in instrument control software is increasing. When developing and maintaining multi-threaded software, the use, management and debugging of threads has become an extremely important issue, which is directly related to the stability of the working state of the signal generator, the correctness of functions and the fluency of user interaction experience, as well as the time of software maintenance. The related issues are localization efficiency and functional scalability. [0003] At present, the usage metho...

AI Technical Summary

Problems solved by technology

[0004] Disadvantage 1: There are many and scattered global resources related to threads, and there is no unified management. The software reusability is poor, which increases the difficulty of software maintenance;

[0005] Disadvantage 2: The interface used by the thread is not uniform, there are many branches, and the coupling is large, resulting in poor consistency and confusion in the use of threads, which increases the probability of software developers making mistakes;

[0006] Disadvantage 3: The relationship between thread synchronization and mutual exclusion is leaked, unsafe, and unreliable, which affects the scalability and correctness of functions;

[0007] Disadvantage 4: Lack of thread debugging functions, thread life cycle cannot be monitored, making it difficult to locate thread-related problems, increasing R&D time and maintenance costs
