Abstract
PURPOSE: To automatically store, retain and update an error information in the main memory connected to several CPU's, not only by supplying a store trouble information to the accessed CPU but also by making it possible to update the error information only in case its CPU corresponds to the descrimination information.
CONSTITUTION: When an error is caused in the main memory connected to several CPU's, the discrimination No. of CPU corresponding to the error information is stored in the store means 101 of the error store control part 11. When the store contents of means 101 are read by access from CPU and are supplied to its CPU, the comparison means 109 compares CPU discrimination No. stored in the means 101 with the discrimination No. of accessed CPU, and resets the means 101 through the store control means 102 by the conforming signal at the time of conformity, by which it is made possible to update the error information of the means 101. Accordingly, the error information is stored, retained and updated automatically, an error reset cycle becomes unnecessary, and the memory access of CPU can be controlled easily.
