main memory stack
主存栈;［主记忆堆叠］
Some systems permit an unlimited number of stacks to reside in main memory with two of them operational at any moment. The operating system has access to all stacks simply by placing new stack addresses in the current stack pointers. Each operational stack has its own stack pointer, its individual upper and lower limit detectors, as well as it s stack fault vector which points to the user's diagnostic and recovery program.
有些系统允许任意多个栈常驻主存, 其中两个在任何时候均可操作。只要将新栈址送入当前栈指示器,操作系统就可存取所有的栈。 每个操作的栈都有自己的栈指示器,各自专用的上、下限检测器,以及指向用户的诊断和恢复 程序的栈故障向量。 |
