<P>PROBLEM TO BE SOLVED: To reduce overheads by exclusive processing in a multiprocessor system, and to output data generated as a result of I/O control onto a screen of a terminal by using an exclusive control program without using a general purpose OS. <P>SOLUTION: The multiprocessor system includes a plurality of processors, a memory shared by the plurality of processors, and an I/O, and is capable of executing the I/O control by executing a plurality of first programs in the plurality of processors under the operation of a general purpose OS. The multiprocessor system includes a plurality of buffers for storing data generated by the processing of the first program secured in the memory corresponding to each of the plurality of first programs, and a second program to be executed in one of the processors under the situation that the general purpose OS is not operated, and by the execution of the second program, the data generated by the processing of the first programs and stored in the plurality of buffers is selected and outputted to a screen of the terminal. <P>COPYRIGHT: (C)2013,JPO&INPIT |
