Abstract
PURPOSE: To make an operation load of CPU uniform, by constituting a request task is interrupted to the CPU lower in running level.
CONSTITUTION: The running level of CPU-A, CPU-B corresponding to the registers RG-A and RG-B are rewritten. When the interruption processing request signal is produced externally, the comparison circuit CMP1 compares the registers to find out CPU executing lower level. On the other hand, the level relating to the task is displayed on the register RDL, and when the task ready state, the comparator CMP-2 is operated, and the level of the register RDL and that found with the comparator CMP1 are compared. As the result of comparison, if the level at CPU side is lower, an interruption signal is given to this CPU to start the operation. Thus, interruption is given without fail to the CPU of low running level, the task is made uniform.
