Each dedicated processor (scientific calculation processor 201, general-purpose processor 20-'2, data storage processor 20
-3 and the communication processing processor 2O-4) exchange information with each other via the shared memory 10.

For example, consider a case where data is sent from the general-purpose processor 20-2 to the scientific calculation processor 20-1.

In this case, the general-purpose processor 20-2 first writes the data into a predetermined area of the shared memory 10.

The scientific calculation processor 20-1 detects that data has been written in the area, reads the written data, and uses the data to perform scientific calculation processing.

These operations are performed by the input/output control unit 4O-n (in the example of progress,
Since the data transfer is executed without going through the input/output control units 40-1 and 40-2), the data transfer is executed at high speed.

Similarly, all information is exchanged between other dedicated processors via the shared memory 10.

Next, for comparison with the present invention, the operation of an example of a conventional functionally distributed information processing system will be described with reference to FIG.

Each dedicated processor exchanges information with each other via the input/output control unit 40-m.

For example, consider a case where data is sent from the general-purpose processor 20-6 to the scientific calculation processor 20-5.

In this case, the general-purpose processor 20-6 first sends the data to the input/output controller 40-5 (input connected to the scientific calculation processor 20-5) via the input/output controller 40-6 using the I10 instruction. output control unit) (performs input/output processing using the I10 instruction).

The input/output control unit 40-5, which has received the data in this way, sends the data to the scientific calculation processor 20-5.

[Effects of the Invention] As explained above, the present invention enables the exchange of information between the dedicated processors by exchanging information between the dedicated processors via the shared memory without going through each input/output control unit. This has the effect of being able to be executed at high speed.
