ABSTRACT:
An information processing system comprises: plural processors; a shared memory connected to the plurality of processors for enabling communication between the processors; a unit disposed in the shared memory for storing information for specifying a processor connected thereto; and a unit for checking, when a first processor communicates with a second processor, whether or not the first and second processors are connected to the shared memory for direct access thereto by referring to the information storing means. A method of communication between processors used with a multiprocessor system, comprises the steps of: storing information for specifying a processor connected to the shared memory for direct access thereto in a predetermined register of the shared memory; feeding a communication instruction for instructing a first processor to communicate with a second processor via the shared memory; checking, in response to the communication instruction, whether or not the first and second processors are connected to the shared memory to enable direct access; storing communication information from the first processor in the shared memory, in response to confirmation that the first and second processors are connected to the shared memory; feeding a communication read interruption from the shared memory to the second processor; and reading out, in response to the communication read interruption, the communication information from the shared memory to feed the communication information to the second processor.
