Discussion on Technology of Real-time Exception Handling

After analyzed status quo of exception handling technology of no real-time systems, advantages and disadvantages of mechanisms based on programming language and operating system are compared in this paper, followed this, the essential requirements, desirable requirements and performance goals in real-time systems are discussed. In order to design an exception handling mechanism adaptive to real time systems, discussed exception expression, criticality management and reliability check and so on, they will become guidelines for designing real time exception handling mechanism. At last, real-time exception handling technologies are summarized, at the same time, related work and future trends of research in this field are listed.
