摘　　要：Nucleus PLUS是新一代的嵌入式实时多任务操作系统内核。在多核操作系统环境下,同一时刻多任务同时访问内核,自旋锁可以很好地处理不同处理器之间存在的同步与互斥问题,但自旋锁如果使用不当,极易产生死锁,造成应用层功能无法实现,所以很有必要对自旋锁展开重点测试。通过对自旋锁机制的研究,提供了一种针对自旋锁的测试方法,避免自旋锁在使用中产生死锁。Nucleus PLUS is a new generation of embedded real-time multitasking operating system kernel. In the multi-core operat-ing system environment, multiple tasks simultaneously access the kernel at the same time, and the spin lock can handle the synchro-nization and mutual exclusion that exist between different processors. However, if the spin lock is used improperly, that can easily cause a deadlock, and the application layer function can not be realized. So the spin lock test is very necessary. Through the study of the spin lock mechanism, this paper provides a test method for the spin lock to avoid the spin lock in the use of deadlock.
