【摘要】 本文从原理出发,对3700系统死机的根源进行了探索。作者认为,死机是由死循环造成的,且绝大多数死循环都与中断有关,而RACKO-TACKO菊花链及错误的返回地址则是引起死机的主要原因。通过对几个死机实例的详尽分折,作者也提出了寻找和分折死循环的一般性方法。更多还原

【Abstract】 Deng Kequan. On Lock-up Problem in 3700 System. WLT, 1993, 17(5): 381～386 Based on the principles of operation 0 the real causes of the lock-up problem in 3700 system have been detailed. The author holds that lock-up is caused by endless loops,most of which relate to interrupts,and that RACKO-TACKO daisy-chain and incorrect returned address are two major roots of the lock-up problems, By analysing several lock-up examples.some general measures for seeking and analysing endless loops are also put forward.更多还原
