ABSTRACT:
In an extended buffer memory shared among a plurality of processors and operable to carry out a data transfer operation to and from one of the plurality of processors which is logically connected to the extended buffer memory, each of a plurality of connection information indicating means indicates whether or not each of the plurality of processors is logically connected to the extended buffer memory. Test information indicating means indicates, by test information having a predetermined logic value, that one of the processors is capable of carrying out a test. The test information having the predetermined logic value is capable of setting the test information indicating means when all of the plurality of connection information indicating means indicates that all of the plurality of processors are logically disconnected from the extended buffer memory. One of the data processors can automatically carry out the test for the extended buffer memory when the test information indicating means has the test information having the predetermined logic value.
