In this case, the write data output from the central processing unit 10 causes the serial communication control circuit 4, as shown in FIG.
Ability to be universal information of each peripheral device obtained by communicating with each peripheral device through the parallel communication control circuit 6 and the network control circuit 8 (bidirectional availability, communication speed, processing speed, operating rate, graphic Peripheral device management data list 23 in which information regarding drawing availability, image compression availability, dither processing availability, image enlargement / reduction availability, floating point operation availability, etc. is summarized, and each peripheral equipment as shown in FIG. Peripheral device operation that summarizes information about the current status of each peripheral device (operating status, processing request status, request content, power supply status, error status, etc.) obtained based on the latest information when communicating with The status management data list 24 is stored, and the peripheral management data list 23 and the peripheral device operation status management data list 24 are referred to. By being so like capacity and operation status of each peripheral device is found.

Next, the operation of this embodiment will be described with reference to the flow charts shown in FIGS. First, when the central processing unit 10 concentrates overloaded processing that cannot be adequately handled by the performance of the central processing unit 10, the central processing unit 10 requests the peripheral device to perform a part of the processing. Is checked (step ST1), and if there is a process that can be requested to the peripheral device, the peripheral device management data list 23 stored in the storage device 11 is referred to and the desired process can be executed. It is checked whether or not there is a peripheral device having such a capability (step ST2). If a peripheral device capable of executing the requested processing is found (step ST3), the peripheral device operation status management data list 24 stored in the storage device 11 by the central processing unit 10 is obtained.
Is referred to (step ST4), and a peripheral device in a state in which a process can be requested is found from all applicable peripheral devices (step ST5).

At this time, the power-off operation, the original processing being executed, and the processing already requested for other processing are excluded from the target. When the situation is the situation shown in the peripheral device operation situation management data list 24 of FIG. 4, the first printer device 14, the second printer device 12, and the third printer device 16 are all peripheral devices that cannot request processing. To be judged. When there is only one requestable peripheral device (step ST6), the central processing unit 10 selects the control circuit corresponding to the peripheral device from the serial communication control circuit 4, the parallel communication control circuit 6, and the network control circuit 8. The peripheral device is requested to perform processing via this control circuit (step ST7), and information indicating that the process is being requested is written to the peripheral device operation status management data list 24 (step ST8). At this time, if a plurality of requestable peripheral devices are found (step ST6), the central processing unit 10 determines the optimum peripheral device according to the contents of the processing desired.

For example, if the processing to be requested is processing of image data (step ST14), it takes a lot of time to send and receive the data, so the peripheral processing data list 23 is referred to by the central processing unit 10. At this time, among the processing request candidates in the plurality of peripheral devices, the peripheral device with the highest communication speed is set as the optimum candidate (step ST15), and the processing request is issued to this peripheral device, and at the same time, on the display device 3. A message indicating the name of the peripheral device that requested the processing, the details of the requested processing, and the like is displayed (step ST16). Further, if the processing to be requested is graphic processing (steps ST14 and ST1)
7), it takes longer to complete the requested processing,
Since it is highly possible that the original work of the peripheral device (for example, a print request if the peripheral device is a printer device) occurs during the processing and the requested processing is interrupted, the central processing unit 10 When the peripheral device management data list 23 is referred to, a plurality of peripheral devices are selected as candidates from the process request candidates in the plurality of peripheral devices, a process request is issued to the peripheral device, and a display device is displayed. A message indicating the name of the peripheral device that requested the processing, the details of the requested processing, etc. is displayed on step 3 (step ST1).
8). As a result, even if the processing requested by any of these peripheral devices is interrupted, the risk of waiting for a long time while the processing is interrupted is avoided.

If the processing to be requested is neither image data processing nor graphic processing (steps ST14 and ST17), when the central processing unit 10 refers to the peripheral device management data list 23, a plurality of peripheral devices are displayed. The processing performance expected value is calculated from among the processing request candidates in (step ST19). In this case, the processing performance expected value is a relative performance value (for example, processing speed) of each peripheral device with respect to the performance value of the central processing unit 10, and the possibility that each peripheral device can execute the requested processing. It is a value that is multiplied by (1-value represented by operating rate), and if the operating rate is 20% during the entire time that each peripheral device is powered on, the remaining 80% will be inactive. Since it is estimated that it is 80%,
It is estimated that the requested processing can be executed with the probability of, and this “1-operating rate” is multiplied by the processing speed to obtain the value.

As a result, no matter how high the processing performance is, the original work frequently occurs, and the priority of the candidates that cannot sufficiently perform the processing requested by the central processing unit 10 is lowered, and conversely. Even if the processing speed is somewhat low, the frequency of occurrence of original work is low, and the priority of candidates that can concentrate on the processing requested by the central processing unit 10 is increased. After the processing performance expected values of these peripheral devices are obtained, the central processing unit 10 compares these processing performance expected values with each other, and the peripheral device having the highest processing performance expected value performs stable processing on average. Is selected as an optimum candidate capable of executing (step ST20), a processing request is issued to this peripheral device, and the name of the peripheral device that requested the process, the content of the requested process, and the like are displayed on the display device 3. A message is displayed (step ST2)
1). Thereafter, the central processing unit 10 generates information indicating that the peripheral device selected by the above-described selection criterion is being requested to perform processing, and the information is written in the peripheral device operation status management data list 24 (step ST8). ).

Thereafter, the central processing unit 10 periodically checks the operating status of the peripheral device requested to be processed among the peripheral devices through the serial communication control circuit 4, the parallel communication control circuit 6, and the network control circuit 8, Based on the operation status obtained by this check operation, the storage device 11
If the peripheral device operation status management data list 24 stored therein is rewritten (step ST9) and there is an original work request for the peripheral device executing the requested processing (steps ST10, ST11), The above-described determination procedure is repeated again, and the next most suitable candidate is selected as the processing request destination, and the same processing is requested again to this candidate. When the requested processing is completed and a signal indicating that the processing is completed is output from the peripheral device (step ST10), one of the serial communication control circuit 4, the parallel communication control circuit 6, and the network control circuit 8 is selected as the peripheral device. This is received by the corresponding control circuit, the execution result of the processing is fetched by the central processing unit 10 (step ST12), and the peripheral device operation status management data list 24 stored in the storage device 11 based on the processing completion content. Is rewritten (step ST1
3).

As described above, in this embodiment, in the portion corresponding to claim 1, all the processing is not performed by only one processing device, but the processing is distributed to the high performance peripheral devices. Therefore, the processing performance of the entire system can be improved. Further, in this embodiment, in the part corresponding to claim 2, communication is performed with each peripheral device, the processing performance of the peripheral device for the requested processing is grasped, and this is managed together in the peripheral device management data list.

Further, in this embodiment, in the portion corresponding to claim 3, there is an accident such that the peripheral device requesting the distributed processing needs to perform the original processing or is accidentally turned off. Also, since the peripheral device with the next highest processing capacity is selected and processing is requested again to this peripheral device, even if the original work request occurs for the peripheral device that requested the processing, the system It is possible to prevent deterioration of the overall processing performance.

Further, in this embodiment, in the portion corresponding to claim 4, the peripherals for which the processing is requested by prioritizing the processing performances of the peripherals and the operating rates of these peripherals in consideration. Since the device is selected, it is possible to give priority to the processing of the peripheral device that is in the inactive state among the peripheral devices, which significantly increases the average processing performance of the entire system. Can be improved. Further, in this embodiment, in the portion corresponding to claim 5, the original processing of the peripheral device that requested the processing occurs in the middle of the request, such as the case of requesting the processing of a long processing time to the peripheral device. When there is a high possibility that processing will be kept waiting, the same processing is requested to multiple peripheral devices for parallel processing, so the requested processing is interrupted midway and the time to complete processing becomes long. Can be prevented, which can significantly improve the average processing performance of the entire system.

Further, in this embodiment, when image processing or the like is performed in the portion corresponding to claim 6, the time required for transmitting the image data to be processed to the request destination rather than the processing itself, and the processing Since it takes a long time to receive the subsequent data from the request destination, we prioritize not only the image processing performance but also the data transmission / reception performance. By reducing the time loss caused by transmission and reception, the most efficient processing can be realized as the entire system. In addition, in this form example, claim 7
In the part corresponding to, the peripheral device for which the processing is requested is notified by displaying in a message format on the display device which peripheral device is requesting the processing.
