  Further, the network I / F 12H is connected to the network N, whereby the system control unit 12 is connected to the terminal device 100 via the network N.

  The device control unit 14 controls an image forming unit 16 having a function of forming an image on a recording medium such as paper. The device control unit 14 includes various hardware such as a CPU 14A, a ROM 14B, a RAM 14C, a non-volatile memory (NVM) 14D, and a communication I / F 14E. The communication I / F 14E is an interface for communicating with the system control unit 12.

  The NVM 12D of the system control unit 12 stores an information processing program, application request resource information, system resource information, and the like, which will be described later.

  The application request resource information is a resource required for executing a new application provided by the new specification system control unit 12 connected to the old specification device control unit 14, the scanner device 18, the facsimile device 20, and the UI device 22. Information about Here, the new application refers to an application that is not provided by the system controller of the old specification, that is, a new function. The resource refers to at least one of the function and the processing performance.

  As an example of the new application, for example, when the performance of the CPU is improved in the system controller 12 of the new specification, the compression processing of the image data at a high compression ratio which is not provided by the system controller of the old specification. And the like. If this is to be realized with the system controller of the old specification, it is necessary to separately add a dedicated hardware accelerator or the like, but this is not necessary in the present embodiment.

  Even when the hard disk is not mounted as in the system control unit 12, if the capacity of the SD memory 12G is increased as compared with the system control unit of the old specification, the unused area of the SD memory 12G is reduced. Since it can be used as an area for storing facsimile data, an image forming apparatus without a hard disk can be equipped with a facsimile communication function as a new application.

  The system resource information is information on resources of the system control unit 12.

  FIG. 2 shows an example of the system resource information. In the example of FIG. 2, resources are classified into two types: functions and processing performance. The functions are classified as level 1 into processors, memories, storages, interfaces, power supplies, and software. The processing performance is categorized into resource consumption and benchmark performance as level 1. Level 1 items are further classified into level 2 items, and level 2 items are further classified into level 3 items. The specifications are set for the items of level 3. For example, examples of resources representing functions include a clock frequency of a processor and a memory capacity of a memory. Further, examples of resources representing processing performance include an occupancy rate of a processor, a memory consumption rate, and the like.

  The NVM 14D of the device control unit 14 stores device request resource information. Similarly, the NVM 18D of the scanner device 18 and the NVM 20 of the facsimile device 20 also store device request resource information corresponding to each device.

  The device request resource information is used by the system control unit 12 to realize real-time processing of data continuously transmitted from each of the device control unit 14, the scanner device 18, and the facsimile device 20 to the system control unit 12. Information on resources required by the unit 12. Here, the real-time processing is processing in which data continuously transmitted from the device control unit 14, the scanner device 18, and the facsimile device 20 to the system control unit 12 needs to be processed in real time. For example, it is a process of copying a plurality of originals. In this case, image data of an image scanned from a document by the scanner device 18 is continuously transmitted to the system control unit 12.

  FIG. 3 shows an example of the device request resource information and the application request resource information.

  For example, the device request resource information excludes unnecessary resources other than those necessary for operating the image forming unit 16 which is a device connected to the device control unit 14 according to design specifications from the system resource information shown in FIG. Resource information.

  The application request resource information is resource information obtained by removing unnecessary resources other than those required for executing a new application from the system resource information.

  In FIG. 3, the grayed-out resources are represented as unnecessary resources, and the specification column is blank. In the example of FIG. 3, resources such as interfaces are unnecessary resources.

  The system control unit 12 performs predetermined image processing on image data continuously transmitted from the scanner device 18 to generate image forming data that can be formed by the image forming unit 16, and generates a device control unit 14. Output to In this copying process, if the system control unit 12 cannot process image data continuously transmitted from the scanner device 18 in real time, the image recorded on the recording medium by the image forming unit 16 may be disturbed. May occur. Therefore, the device request resource information in this case is resource information required of the system control unit 12 so as not to cause a problem such as disturbance of an image recorded on a recording medium by the image forming unit 16.

  Next, a functional configuration of the CPU 12A of the system control unit 12 will be described.

  As shown in FIG. 4, the CPU 12A functionally includes an acquisition unit 50, a calculation unit 52, a determination unit 54, and a notification unit 56.

  The acquisition unit 50 acquires the application request resource information and the system resource information by reading them from the NVM 12D. The acquisition unit 50 requests and acquires the device control unit 14, the scanner device 18, the facsimile device 20, and the UI device 22 via the communication I / F 12E to transmit the device request resource information. As a result, the device control unit 14 reads out the device request resource information from the NVM 14D and transmits it to the system control unit 12 via the communication I / F 14E. Similarly, the scanner device 18 and the like also read device request resource information from the NVM 18D and the like, and transmit the resource request information to the system control unit 12 via the communication I / F 18E and the like.

  The calculation unit 52 calculates a resource allowance of the system control unit 12 when the system control unit 12 realizes real-time processing from the system resource information and the device request resource information acquired by the acquisition unit 50.

  The determination unit 54 determines whether to execute a new application provided by the system control unit 12 of the new specification based on the application request resource information acquired by the acquisition unit 50 and the resource allowance of the system control unit 12 calculated by the calculation unit 52. Is determined.

  When the determination unit 54 determines that the execution of the new application is prohibited, the notification unit 56 notifies the resource conditions necessary for permitting the new application. For example, the notification unit 56 outputs the condition of the resource necessary for permitting the new application to the UI device 22 and displays the same.

  Next, a flow of information processing executed by the CPU 12A of the system control unit 12 will be described with reference to a flowchart shown in FIG. The process shown in FIG. 5 is executed when the operator replaces the system controller of the old specification with the system controller 12 of the new specification and then performs an operation for instructing installation of a new application.

  In step S100, application request resource information and system resource information are obtained by reading from the NVM 12D.

  In step S102, device request resource information is acquired from the device control unit 14, the scanner device 18, the facsimile device 20, and the UI device 22, respectively.

  In step S103, combined resource information in which the application request resource information and system resource information obtained in step S100 and the device request resource information obtained in step S102 are combined into one is generated. FIG. 6 shows an example of the combined resource information.

  In step S104, among the resources described in the device request resource information acquired in step S102, resources for which the margin determination processing in step S108 described below has not been performed are selected as the resources for which the margin is to be determined.

  In step S106, a margin of resources of the system control unit 12 when real-time processing is realized by the system control unit 12 is calculated from the system resource information obtained in step S100 and the device request resource information obtained in step S102. That is, for the resource selected in step S104, the margin is calculated based on the comparison result between the resource described in the device request resource information and the resource described in the system resource information corresponding to the resource.

  In step S108, it is determined based on the resource margin calculated in step S106 whether there is enough room to permit execution of a new application.

  Specifically, for example, it is determined whether or not the margin calculated in step S106 is equal to or larger than a threshold. Here, the method of calculating the margin and the threshold are selected according to the type of the resource.

  For example, the types of resources include a first type of resource for which the presence or absence of a margin should be determined based on the integrated value of the resource and a second type of resource for which the presence or absence of the margin should be determined based on the maximum value of the resource or the version of the specification. , Are roughly divided into

  The first type of resource includes a processor occupancy, a bus occupancy of a memory and a storage, a memory capacity, a storage capacity, and the number of interfaces.

  Hereinafter, an example of the processor occupancy will be described.

  When the processor occupancy R1 in the system resource information is 20 (%), the processor occupancy R2 in the device request resource information is 20 (%), and the processor occupancy R3 in the application request resource information is 30 (%), the margin is given. M1 is calculated by the following equation.

M1 = 100− (R1 + R2 + R3) = 100− (20 + 20 + 30) = 30 (%)

  If the integrated value of the processor occupancy is equal to or less than 100 (%), that is, if the margin M1 is equal to or greater than 0 (%), it may be determined that there is a margin, so the threshold is set to 0 (%). You. Accordingly, in the case of the above example, since the margin M1 (30%) is equal to or larger than the threshold (0%), it is determined that there is a margin.

  Next, a case where the resource is a memory capacity will be described.

  For example, when the memory capacity C1 in the system resource information is 10 (gigabytes), the memory capacity C2 in the device request resource information is 2 (gigabytes), and the memory capacity C3 in the application request resource information is 3 (gigabytes), the margin M2 is It is calculated by the following equation.

M2 = C1-C2 = 10-2 = 8 (gigabyte)

  If the margin M2 is equal to or larger than the memory capacity C3 in the application request resource information, it can be determined that there is a margin, so the threshold is set to the memory capacity C3 (3 gigabytes). Therefore, in the case of the above example, since the margin M2 (8 gigabytes) is equal to or larger than the threshold (3 gigabytes), it is determined that there is a margin.

  In the above example, there is one device request resource information. However, when there are a plurality of device request resource information, the margin may be calculated using the total value of the plurality of device request resource information.

  In order to operate a new application stably, the margin may be calculated using a predetermined stability coefficient K. For example, in the case of the above-described example of the occupancy of the processor, the margin M1 may be calculated by the following equation.

M1 = 100− (R1 + R2 + R3 + K)

  For example, when the stability coefficient K is 25%, the allowance M1 is calculated as follows.

M1 = 100− (20 + 20 + 30 + 25) = 5 (%)

  Also in this case, since the margin M1 (5%) is equal to or larger than the threshold (0%), installation of a new application is permitted. Note that the stability coefficient K may be set according to the type of the resource.

  The second type of resource includes a processor operating frequency, clock frequencies of memories and interfaces, firmware version information, and the like.

  Processor operating frequencies, clock frequencies of memories and interfaces, and the like are important resources that affect data processing performance. Regarding these resources, the device request resource information describes the recommended conditions necessary for operating the image forming unit 16 according to the design specifications, and the application request resource information includes a new application according to the design specifications. It is described as a recommended condition necessary for the operation. If the resource in the system resource information falls below the recommended conditions described in the device request resource information and the application request resource information, it is determined that there is no room since there is no guarantee that the new application will operate stably.

  In addition, since versions of various interfaces and firmware are generally assumed to be backward compatible, it may be considered that a newer version basically corresponds to a function of an older version. Therefore, regarding the versions of various interfaces and firmware, if the version in the system resource information is newer than the version in the device request resource information and the application request resource information, it is determined that there is a margin.

  If the determination in step S108 is affirmative, that is, if it is determined that the resource to be determined has room, the process proceeds to step S110. On the other hand, if the determination in step S108 is negative, that is, if it is determined that the resource to be determined has no margin, the process proceeds to step S112.

  In step S110, of the combined resource information shown in FIG. 6 generated in step S103, the resource to be determined is recorded as having a margin. In the example of FIG. 6, the presence of a margin is indicated by “で”. In the example of FIG. 6, the result of comprehensively determining a function is recorded as “function determination”. The function judgment becomes “○” when all of the resources related to the function are “○”. The same applies to the processing performance. Further, the result of comprehensively determining the function and the processing performance is recorded as “general determination”. The overall judgment is “○” when both the function judgment and the processing performance judgment are “○”.

  On the other hand, in step S112, of the combined resource information shown in FIG. 6 generated in step S103, the resource to be determined is recorded as having no margin.

  In step S114, it is determined whether or not all resources have a margin. When the determination in step S114 is affirmed, the process proceeds to step S116. On the other hand, if the determination in step S114 is negative, the process proceeds to step S104, where an undetermined resource is selected and the same processing as described above is executed.

  In step S116, with reference to the combined resource information, it is determined whether or not it is determined that there is room for all resources. If the determination in step S116 is affirmative, the process proceeds to step S118. On the other hand, if the determination in step S116 is denied, that is, if there is at least one resource determined to have no margin, the process proceeds to step S120.

  In step S118, the application is installed because the execution of the new application provided by the system controller 12 having the new specification may be permitted. Here, “installing” means, for example, expanding a program for executing a new application in the NVM 12D so that the application can be executed.

  On the other hand, in step S120, the execution of the new application provided by the system controller 12 of the new specification should be prohibited, so that the application is not installed and the condition of the resource necessary for permitting the execution of the application is calculated. Then, the calculated conditions are output to the UI device 22 and displayed.

  For example, a case where the resource is the processor occupancy will be described.

  When the processor occupancy R1 in the system resource information is 30 (%), the processor occupancy R2 in the device request resource information is 40 (%), and the processor occupancy R3 in the application request resource information is 40 (%), the margin is given. M1 is calculated by the following equation.

M1 = 100− (R1 + R2 + R3) = 100− (30 + 40 + 40) = − 10 (%)

  In this case, if the processor occupancy R1 is 40% or more, a message indicating that the execution of the application is permitted is displayed on the UI device 22. As a result, the processor occupancy required for executing the application is grasped by the operator.

  By the way, the device request resource information stored in the device controller 14, the scanner device 18, and the UI device 22 of the old specification is usually information calculated corresponding to the system controller 12 of the old specification. . For this reason, when the system controller 12 is replaced (upgraded) with the system controller 12 of the new specification, the calculation standard of the device request resource information stored in the device controller 14 of the old specification is different from that of the system controller 12 of the new specification. There is a case where the resource information is inappropriate for the system controller 12 of the new specification. An example of such device request resource information is a processor occupancy calculated based on the system controller of the old specification.

  Therefore, in calculating the resource allowance of the system controller 12 of the new specification, the device request resource information may be converted to information corresponding to the system controller 12 of the new specification before the processing of FIG. Good.

  Hereinafter, an example of a method of making the device request resource information correspond to the new specification system control unit 12 when the system control unit 12 is replaced with the new specification system control unit 12 will be described.

  When the system control unit 12 executes processing that requires real-time processing after replacing the system control unit 12 with the new specification system control unit 12, an evaluation program for measuring resources of the system control unit 12 is executed. The evaluation program is executed when at least one of print processing, scan processing, and facsimile communication processing is executed individually or in parallel, that is, at least one of the device control unit 14, the scanner device 18, and the facsimile device 20. A program for measuring various resources of the system control unit 12, that is, device request resource information, when data is continuously transmitted from the system control unit 12 to the system control unit 12 and the transmitted data is processed in real time by the system control unit 12. It is. The device request resource information to be measured includes, for example, processor occupancy, memory consumption, storage consumption, memory transfer speed, storage transfer speed, network bandwidth occupancy, bus bandwidth occupancy, and power supply.

  When executing the evaluation program, for example, a print process, a scan process, a facsimile communication process, and the like are executed in parallel according to an instruction of an operator.

  Then, the device request resource information obtained by executing the evaluation program and measured is added to or overwritten in the NVM 12D of the system controller 12 of the new specification.

The device required resource information obtained by the measurement by executing the evaluation program is stored in the NVM 12D of the system control unit 12 of the new specification by adding or overwriting.

  The resources of the system control unit 12 may be measured by executing a benchmark test instead of the evaluation program. For the benchmark test, an appropriate benchmark test may be selected according to the type of the resource.

  Further, when the application request resource information is replaced with the new specification system control unit 12, the calculation standard of the application request resource information is calculated based on the old specification system control unit, similarly to the device request resource information described above. May be.

  Therefore, after acquiring the application request resource information in step S100 in FIG. 5, the application request resource information may be replaced with information corresponding to the system controller 12 of the new specification.

  For example, application request resource information assuming a plurality of existing system control units 12 is stored in a storage device such as a server device (not shown) connected to the network N in advance, and a new specification of the system control unit 12 may be selected, and the selected application request resource information may be temporarily stored in the NVM 12D.

  Further, as another method, a predicted value of the application request resource information is calculated based on a difference in processing performance between the system control unit of the old specification and the new specification, and the calculated prediction value is stored in the NVM 12D as the application request resource information. You may do so.

  Hereinafter, a specific example will be described.

  For example, the application request resource information acquired in step S100 is information based on the processor processing performance score Sc1 (= 100) of the old specification system control unit 12 (a numerical value indicating the processor processing performance under specific conditions). Assume that the processor occupancy P1 of the system controller of the old specification is, for example, 50%.

  In this case, a processor processing performance score Sc1 'as application request resource information necessary for executing a new application is calculated by the following equation.

Sc1 ′ = Sc1 × P1 = 100 × 0.50 = 50

  If the score Sc2 of the processor performance of the system controller 12 of the new specification is twice the score Sc1 of the processor performance of the system controller 12 of the old specification, that is, Sc2 = 200, the system controller of the new specification Of the processor P2 is calculated by the following equation.

P2 = Sc1 '/ Sc2 = 50/200 = 25 (%)

  That is, since the score Sc2 of the processor processing performance of the system control unit 12 of the new specification is twice the score Sc1 of the processor processing performance of the system control unit 12 of the old specification, the processing performance per unit time is double. . Therefore, the system controller 12 of the new specification can perform data processing in a shorter time than the system controller of the old specification, and the occupancy P2 of the processor of the system controller 12 of the new specification is smaller than that of the old specification. It is の of the occupancy of the processor of the system control unit.

  As described above, in the present embodiment, before installing a new application, the resource margin is calculated to determine whether the new application can be executed. For this reason, it is suppressed that the application is installed despite the fact that the resource margin for executing the application is insufficient, and the occurrence of troubles such as image disorder is suppressed.
