摘要

The processing system includes a central processor, memory and a number of input-output devices. Devices provide for powering-off the system. The state of all memory locations and of each of the input-output devices is saved when the powering-off devices are activated. All memory locations and each of a number of input-output devices are restored to the state held at power-off time upon powering the systemback on. The power-off devices comprises units for disabling all interrupts in the system and for halting operation of each input-output device. The memory location saving unit activates an isolated area of memory.
