Abstract:

commercial symmetric multi-processor (SMP) operating system mutex strategy,focusing on three key issues mutually exclusive strategies:Spinlocks design,long-term mutually exclusive failure,and deadlock issues.Learn advanced commercial analysis of the characteristics of the different types of shared resources and design an efficient spin lock and research deadlock competitive conditions produce conditions based on a clear solution.Finally,in the MPC7410 platform on system performance measurement,the results proved mutually exclusive strategies,small time overhead cost of effectively improve the processing speed of a computer system,a wide range of applications in the the airborne embedded computer field.

Key words: multi-operating system;short-term mutually exclusive;spinlock;Long-term mutually exclusive
