Abstract

PURPOSE: To carry out the life and death management of other system CPU easily and properly by performing the life and death management of other system CPU by the memory register which is possible to make access to the respective CPU commonly.
CONSTITUTION: CPU-A1 regiters the pattern of "Life" of the self-CPU to the memory register 30 which is commonly accessible at a regular interval. Viewing if the pattern of CPU-B2 is "life" or not, if it is "life", "death monitor" is carried out. If it is "death monitor", it is made to be "death". If it is "death", CPU-B is considered as the death condition and the treatment of death is carried out. Similarly, CPU- B2 registers "life" pattern of self-CPU to the memory register 30 at the same interval and moves the pattern of CPU-A from "life" to "death monitor" and from "death monitor" to "death", and if it is "death", the treatment of death of CPU-A is carried out.
