Abstract

PURPOSE:To shorten the time required for transferring the storage contents of a communication processor to a central processor by executing a data transfer between storage areas divided into plural areas. CONSTITUTION:A central processing unit 1 has a secondary storage medium 3, and the secondary storage medium 3 is constituted of storage areas 31 and 32. A storage area dividing means 21 of a communication processor 2 discriminates the number of pieces of the storage areas of the secondary storage medium, and divides a storage area of the communication processor 2 into storage areas 23 and 24. An inter-area transfer means 22 transfers data of the storage areas 23 and 24 to the central processing unit 1 through an inter- system communication channel 4. An inter-area transfer means 11 discriminates a transmitting origin area of the transmitted data, and records it in the storage area 31 or 32 of the secondary storage medium 3. Subsequently, a storage area coupling means 12 couples the storage contents recorded in the storage areas 31 and 32.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the overall configuration of this embodiment. First, the configuration of this embodiment will be explained with reference to FIG. The central processing unit 1 is connected to a communication processing unit 2 via an intersystem communication path 4. The central processing unit 1 has a secondary storage medium 3, and the secondary storage medium 3 is composed of a storage area 31 and a storage area 32. Storage area 31 and storage area 3
2 are each composed of one storage device. The storage area dividing means 21 divides the storage area in the communication processing device 2 into a storage area 23 and a storage area 2 based on the number of storage areas of the secondary storage medium 3.
Divide into 4. The inter-area transfer means 22 is a storage area 23 within the communication processing device 2.
and the data in the storage area 24 are transferred to the central processing unit 1 via the intersystem communication path 4. The inter-area transfer means 11 determines the source area of the data transmitted via the inter-system communication path 4, and transfers the data to the storage area 3 of the secondary storage medium 3.
1 or the storage area 32. Storage area combining means 12
combines the storage contents of the communication processing device 2 recorded in the storage area 31 and the storage area 32.

That is, as shown in FIG. 1, this embodiment includes a central processing unit 1 connected to a secondary storage medium 3, and a central processing unit 1 connected to this central processing unit 1 via an intersystem communication path 4. The secondary storage medium 3 includes a communication processing device 2 having a storage area for storing data to be transferred to the secondary storage medium 3. Furthermore, as a feature of the present invention, the secondary storage medium 3 has two storage areas 31 and 2. 32, the communication processing device 2 has a storage area dividing means 21 that divides the storage area of the device into a number equal to the number of storage areas of the secondary storage medium 3, and a storage area division means 21 for dividing the storage area of the device into a number equal to the number of storage areas of the secondary storage medium 3, and a storage area dividing means 21 for each of the divided storage areas 23 and 24. The central processing unit 1 is equipped with storage area division transfer means 21 that sends stored data to the intersystem communication path 4, and the central processing unit 1 determines the source area of the incoming data and transfers the data to the storage area that is a secondary storage medium. The apparatus includes inter-area transfer means 11 for recording in each of storage areas 31 and 32, and storage area combination means 12 for combining the storage contents of storage areas 31 and 32, respectively.

Next, the operation of this embodiment will be explained. Although this invention depends on the number of storage areas in the secondary storage medium of the central processing unit, the case where the number of storage areas is "2" will be explained. First, processing in the communication processing device 2 will be explained. The storage area dividing means 21 determines the number of storage areas of the secondary storage medium 3 and divides the storage area of the communication processing device 2 into a storage area 23 and a storage area 24, as shown in the processing flow of FIG. Then, as shown in FIG. 3, the inter-area transfer means 22 copies the data in the storage area 23 to the buffer 25 by the size, copies one piece of data from the storage area 24 to the buffer 26 by the size, and transfers the data from the storage area 23 to the buffer 26, respectively. The data is transferred to the buffers 13 and 14 of. Next, processing in the central processing unit 1 will be explained. The inter-area transfer means 11 writes to the storage area 31 when the transfer to the buffer 13 is completed. Further, when the transfer to the buffer 14 is completed, it is written to the storage area 32. The storage area 31 and the storage area 32 are then combined by the storage area combining means 12 when all the transfers are completed.
