PURPOSE:To obtain the continuation of data and to shorten a data transfer time, by providing storage element which are accessed by mutually independent processors in a storage device, and replacing data among those element groups instantaneously. CONSTITUTION:The storage device 19 is accessed by both data processors 20 and 21 and its storage elements are separated into storage elements 22 and 23 for data processors 20 and 21; they are further divided into storage elements 22-a and 23-a for writing and storage elements 22-b and 23-b for reading. When processing completion signals 33 and 34 are outputted from the data processors 20 and 21, a both-processing completion signal 47 is generated to disconnect the storage device 19 from the processors 20 and 21; and then all data in the storage element 22-a are transferred to the element 23-b and data in the element 23-a are transferred to the element 22-b by data replacement signals 48 and 49. Therefore, while the continuation of data processing is secured, the data are transfered together at a time, so that the high-speed data transfer is realized. |
