Publication number: 20170082989Abstract: A transport control system divides a series of data-processing operations into mutually independent processes, and causes the process execution units to execute the respective processes. The data input or output by each process execution unit is stored in the data storage separate from the process execution unit, and transfer of the data between the respective process execution units is performed via the data storage instead of being performed directly between the process execution units. By separating the processes from each other and also separating the processes from the data in this manner, without affecting process execution units other than a process execution unit to be changed and the data storage, the process execution unit to be changed can be changed to a different process execution unit.Type: ApplicationFiled: January 30, 2015Publication date: March 23, 2017Applicant: Murata Machinery, Ltd.Inventors: Kenji KUMAGAI, Hisato YONEDA
