Description

[Description of related applications]
The present invention is based on a Japanese patent application: Japanese Patent Application No. 2012-095064 (filed on April 18, 2012), and the entire contents of the application are incorporated and described herein by reference.
The present invention relates to a design support device, a design support method, and a program for a message processing device, and more particularly to a design support device, a design support method, and a program for a message processing device that efficiently process a large amount of received messages.

  In recent years, it has been required to create new added value by processing information obtained from sensors and terminals in real time. Generally, such information arrives at a server as a message.

  FIG. 11 is a block diagram illustrating the configuration of a message processing device that processes messages. Referring to FIG. 11, the message processing apparatus 105 includes a receiving unit 111 and a calculation processing unit 112.

  A message arrives at the message processing device 105 in FIG. 11 via the network. Here, the network is, for example, a wired network such as Ethernet (registered trademark) or a wireless network such as Zigbee (registered trademark) or Bluetooth (registered trademark). The receiving unit 111 has a form such as a network interface controller (NIC), for example. When receiving a message from the network, the receiving unit 111 sends it to the calculation processing unit 112. The calculation processing unit 112 is realized by a processor, for example. For communication between the reception unit 111 and the calculation processing unit 112, for example, a communication path in a server such as PCI Express is used. When the calculation processing unit 112 receives a message from the reception unit 111, the calculation processing unit 112 executes calculation processing according to a predetermined application program.

  A technique for processing a large amount of electronic messages received by the server is described in, for example, Patent Document 1 and Patent Document 2. Non-patent document 1 describes an XML parsing technique for parsing an XML (Extensible Markup Language) document in a hardware environment as an example.

F. El-Hassan et al., “SCBXP: An Efficient CAM-Based XML Parsing Technique in Hardware Environments,” IEEE transaction on Parallel and Distributed Systems, Volume 22, Issue 111, pp. 1879-1887, 2011.

  The disclosures of the above-mentioned patent documents and non-patent documents are incorporated herein by reference. The following analysis was made by the present inventors.

  FIG. 12 is a block diagram schematically showing a design procedure of the message processing apparatus 105 shown in FIG. The application program that defines the processing contents of the electronic message processing apparatus 105 is usually given as source code written in a program language. The source code of the application program is converted into an object code that can be executed by the calculation processing unit 112 such as a processor by using the compiler 113. By placing the object code on a processor provided in the calculation processing unit 112 and executing the object code, a desired message processing is realized.

  However, when a normal server receives a large amount of messages, it is difficult to realize real-time processing. For example, the processing speed of the calculation processing unit 112 may not be able to cope with messages that arrive in large quantities. In addition, the communication path connecting the receiving unit 111 and the calculation processing unit 112 may not be able to handle a large amount of incoming messages.

  Techniques for solving the above problems are described in Patent Document 1 and Patent Document 2. FIG. 13 is a block diagram schematically showing the techniques described in Patent Literature 1 and Patent Literature 2. As shown in FIG. Referring to FIG. 13, the message processing apparatus 106 further includes a selection unit 114 in addition to the reception unit 111 and the calculation processing unit 112.

  After receiving the message by the receiving unit 111, the selection unit 114 checks the message according to a predetermined specification, and when a message matching a predetermined condition is found, discards the message. Thereby, even if a large amount of electronic messages are transmitted, it is possible to prevent the calculation processing unit 112 from processing electronic messages that do not include important information.

  On the other hand, FIG. 14 is a block diagram showing a configuration of a message processing apparatus 107 studied by the inventors as a technique for solving the above-described problem. Referring to FIG. 14, the message processing device 107 further includes a conversion unit 115 in addition to the reception unit 111, the selection unit 114, and the calculation processing unit 112.

  When the conversion unit 115 finds a message that matches a predetermined condition among the messages output from the selection unit 114, the conversion unit 115 converts the message according to a predetermined rule. As a result, even if a large amount of messages are transmitted, the calculation processing unit 112 can process a message from which unnecessary data in the message is deleted. According to the message processing device 107 illustrated in FIG. 14, unlike the message processing device 106 illustrated in FIG. 13, only the necessary information of the information included in the message can be processed by the calculation processing unit 112.

  However, the message processing device 106 shown in FIG. 13 or the message processing device 107 shown in FIG. 14 may cause the following problems.

  The application program executed by the calculation processing unit 112 does not clearly specify a condition for discarding a message or a rule for converting a message. Therefore, in order to implement the message processing devices 106 and 107, the selection unit 114 in FIGS. 13 and 14 and the conversion unit 115 in FIG. 14 must be separately designed. In addition, the conditions for discarding the electronic message and the rules for converting the electronic message are different for each application program. Therefore, the design needs to be changed every time the application program is changed. However, a technique for automating the design of the selection unit 114 and the conversion unit 115 is not known.

  Therefore, according to the related art described above, it is difficult to automatically design a device that flexibly extracts only important information necessary for a received message. This is an obstacle to realizing the message processing apparatus that processes the message at high speed and flexibly as illustrated in FIG. 13 or FIG.

  Therefore, it is desired to support the design of a message processing device that filters in advance a message or a part of information included in the message according to the processing contents of an application program that processes the message. An object of the present invention is to provide a design support apparatus, a design support method, and a program that contribute to such a demand.

To do.

  According to such a design support device, it is possible to automate the design of the message processing devices (106, 107) for filtering messages in advance according to the processing contents of the application program for processing messages. This is because the selection unit generation unit (63) automatically sets configuration information of a selection circuit (selection unit 114 in FIGS. 13 and 14) that filters a message according to whether or not a message processing result is output from the application program. This is because

  FIG. 2 is a block diagram illustrating another configuration example of the design support apparatus according to the embodiment. Referring to FIG. 2, the design support apparatus includes a second filter condition extraction unit (64) and a conversion unit generation unit (65).

Moreover, a conversion part production | generation part (65) produces | generates the structure information of a conversion part (115) so that the conversion part (115) may convert a message | telegram based on a 2nd filter condition.

  According to such a design support apparatus, it is possible to support the design of a message processing apparatus that filters a part of information included in a message in advance according to the processing content of an application program that processes the message. This is because the conversion unit generation unit (65) is configured to convert the message based on the second filter condition extracted from the application program depending on whether the processing result of the message is affected. Is generated automatically.

  According to the design support apparatus according to the above-described embodiment, even when a large amount of message information is received, a message processing device that realizes high-speed message processing by passing only important information to the calculation processing unit is automatically designed.

  FIG. 3 is a flowchart showing an example of the operation of the design support apparatus of the present embodiment. With reference to the block diagram of FIG. 2 and the flowchart of FIG. 3, the operation of the design support apparatus of the present embodiment will be described in detail.

  The program storage unit 51 of the storage device 50 stores in advance an application program to be designed and executed by the calculation processing unit of the message processing device. The application program may be stored as source code or may be stored after being converted into a format that can be executed by a processor or the like. In the present embodiment, as an example, it is assumed that it is stored in the form of source code.

  First, the program input unit 61 reads an application program from the program storage unit 51 of the storage device 50 (step A1).

  Next, the first filter condition extraction unit 62 extracts a condition for generating an output for each output in the application program, and sets this as a “first filter condition” (step A2).

  Next, the selection unit generation unit 63 generates circuit information of the selection unit based on the first filter condition.

  Next, the operation of the design support apparatus (FIG. 2) according to this embodiment will be described based on a specific example.

  In this embodiment, the message processing apparatus 107 shown in FIG. Referring to FIG. 14, the message processing apparatus 107 includes a reception unit 111, a selection unit 114, a conversion unit 115, and a calculation processing unit 112.

  The receiving unit 111 receives a message from the network. The receiving unit 111 disassembles the message into each field of the header of the message and each field of the data (payload) portion of the message according to the message specification given in advance, and passes the decomposed message to the selection unit 114.

  In general telegrams, the specification of the data part is uncertain, so it is difficult to decompose the data part into fields. In the present embodiment, since a message configured in accordance with a predetermined specification is targeted, the data portion can also be decomposed in units of fields.

  The selection unit 114 inspects the electronic message received from the reception unit 111 according to a predetermined specification, and discards the electronic message when a electronic message matching a predetermined condition is found. In addition, the selection unit 114 transmits other messages to the conversion unit 115.

  The conversion unit 115 inspects a message field according to a predetermined specification for the message received from the selection unit 114, and converts the message by discarding a message field that matches a predetermined condition. . Furthermore, the conversion unit 115 transmits the converted message to a CPU or memory in the server via a communication path in the server such as PCI Express.

  The calculation processing unit 112 processes the message received from the conversion unit 115 by an application program designated in advance.

  The processing by the application program executed by the calculation processing unit 112 is the same as the processing by the application program executed by the calculation processing unit 112 of the message processing apparatus 105 of FIG.

  According to the message processing device 107 shown in FIG. 14, messages unnecessary for processing and data unnecessary for processing are discarded by the selection unit 114 and the conversion unit 115, and only data necessary for processing arrives at the calculation processing unit 112. To do. Therefore, according to the message processing device 107, it is possible to process more messages compared to the message processing device 105 without changing the processing contents in the calculation processing unit 112.

  In the present embodiment, a method will be described in which the design support when the selection unit 114 and the conversion unit 115 included in the message processing device 107 are realized by an electronic circuit is performed by the design support device (FIG. 2).

  The program storage unit 51 of the storage device 50 stores in advance an application program to be executed by the calculation processing unit 112 of the message processing device 107 to be designed. The application program may be stored as source code or may be stored after being converted into a format that can be executed by a processor or the like. In this embodiment, it is assumed that the application program is stored in the program storage unit 51 as source code.

  FIG. 4 illustrates an application program in the present embodiment. Referring to FIG. 4, the source code of the application program is described in ANSI-C language. In FIG. 4, portions of the source code that are not necessary for explanation are omitted. The source code may be described in a programming language other than ANSI-C.

  The message processed by the application program shown in FIG. 4 is represented by a structure having three fields, city, temp, and rain, as shown in the first line of the source code in FIG.

  The message processed by the application program of this embodiment is configured in accordance with a predetermined specification that there are a plurality of attribute / value pairs. In this embodiment, such a message is referred to as a “structured message”. As a structured message, a message based on a language specification such as HTML (Hypertext Markup Language) or XML (Extensible Markup Language), a structure, a class, etc. This includes electronic messages expressed by value and other various electronic messages. In this way, by focusing only on the structured electronic message, it is possible to extract important information (for example, information related to processing of the application program) from the electronic message.

  The fields city, temp, and rain included in the structure represent the city, temperature, and precipitation, respectively. The application program of FIG. 4 integrates and outputs the precipitation rain described in the telegram in which the city city is Tokyo.

  In the fifth line of the source code in FIG. 4, a message is received and stored in the structure variable ev. Here, the function get_event () is a function that receives one message from the receiving device. Line 6 checks whether the value of field city in the message is Tokyo. If the value of city is not Tokyo, nothing is done for the message. In the seventh line, the value of the field rain in the message is added to the total precipitation total. The 8th line outputs the total precipitation after calculation. The function send_result () is a function for outputting data. In each line of the source code, a comment after the double slash “//” is a comment sentence.

  FIG. 5 illustrates a message to be processed by the application program shown in FIG. Referring to FIG. 5, the value of the field city of the message on the first line and the message on the third line is Tokyo. Therefore, the electronic message on the first line and the electronic message on the third line are processed by the application program shown in FIG. On the other hand, since the value of the field city of the message on the second line is Osaka, it is not processed by the application program of FIG. Therefore, the message on the second line is an unnecessary message for the application program of FIG.

  Further, the value of the field temp of each message shown in FIG. 5 is not processed by the application program of FIG. Therefore, the data included in the field temp is unnecessary for the application program of FIG.

  FIG. 6 illustrates input / output of the reception unit 111 corresponding to the application program illustrated in FIG. Referring to FIG. 6, the reception unit 111 receives a message, disassembles it into fields, and passes it to the selection unit 114. The message targeted by the application program shown in FIG. 4 has three fields, city, temp, and rain. Corresponding to these fields, the receiving unit 111 in FIG. 6 has three outputs of city, temp, and rain.

  In this embodiment, it is assumed that the receiving unit 111 in FIG. 6 is provided in advance. As an example of the design method of the receiving unit 111, the method described in Non-Patent Document 1 can be used. However, the design method of the receiving unit 111 is not limited to this.

  Next, a procedure for automatic design of the selection unit 114 and the conversion unit 115 by the design support apparatus according to the present embodiment will be described.

  First, the program input unit 61 reads an application program from the program storage unit 51 of the storage device 50 (step A1 in FIG. 3).

  Next, the first filter condition extraction unit 62 extracts a condition for generating an output for each output in the application program, and sets this as a “first filter condition” (step A2 in FIG. 3). ).

  For example, the filter condition extraction unit 62 can use a technique such as a control data flow graph (CDFG) analysis to extract the conditions. However, the condition extraction method by the filter condition extraction unit 62 is not limited to this.

  In the application program shown in FIG. 4, the condition for executing the output operation send_result () is the condition “ev.city ==“ Tokyo ”” of the if statement on the sixth line. Therefore, the filter condition extraction unit 62 extracts the condition “ev.city ==“ Tokyo ”” as the first filter condition.

  As described above, the first filter condition is expressed by a logical expression of each field constituting the message.

  Next, the selection part production | generation part 63 produces | generates the circuit information of the selection part 114 based on 1st filter conditions (step A3 of FIG. 3). The selection unit 114 is a circuit that discards a message when the received message does not satisfy the first filter condition. The selection unit generation unit 63 writes the circuit information of the selection unit 114 in the selection unit storage unit 52 of the storage device 50.

  The first filter condition is expressed by a logical expression of each field constituting the message. Therefore, the selection unit generation unit 63 generates circuit information of a logic circuit that realizes this logical expression as circuit information of the selection unit 114.

  FIG. 7 is a block diagram illustrating an example of the configuration of the generated selection unit 114. Referring to FIG. 7, the selection unit 114 includes external input terminals city, temp, rain, external output terminals city, temp, rain, a condition determination circuit 116, and a gate 117.

  The condition determination circuit 116 reads a value from the external input terminal city and checks whether the value is Tokyo. The condition determination circuit 116 sends true to the gate 117 if the value of city is Tokyo as a result of the inspection, and false otherwise.

  When the value of the condition determination circuit 116 is true, the gate 117 sends the values of the external input terminals city, temp, and rain to the external output terminal. When the value of the condition determination circuit 116 is false, the gate 117 Output nothing.

  According to the selection unit 114 illustrated in FIG. 7, only a message whose city value is Tokyo is sent to the conversion unit 115, and other messages are discarded. That is, according to the selection unit 114, a message unnecessary for the calculation process is discarded, and only a necessary message is sent to the calculation processing unit 112.

  FIG. 8 illustrates an electronic message transmitted from the selection unit 114. Comparing the message in FIG. 8 with the message in FIG. 5, in the message in FIG. 8, the message in the second line of the message in FIG. 5 whose field city value is Osaka is the selection unit shown in FIG. 7. 114 has been discarded.

  The selection unit generation unit 63 records the circuit configuration information of the selection unit 114 illustrated in FIG. 7 in the selection unit storage unit 52 of the storage device 50.

  Next, the second filter condition extraction unit 64 extracts an input that affects the output in the application program, and sets this as a “second filter condition” (step A4 in FIG. 3).

  For example, the filter condition extraction unit 64 can use a technique such as Cone of Influence Reduction to extract the input. However, the method by which the filter condition extraction unit 64 extracts the input is not limited to this.

  In the application program shown in FIG. 4, only the city and rain of the fields city, temp, and rain included in the message affect the output, and temp does not affect the output. Therefore, the filter condition extraction unit 64 extracts city and rain as the second filter condition.

  The second filter condition is expressed by designating a subset of each field constituting the message.

  Next, the conversion part production | generation part 65 produces | generates the circuit information of the conversion part 115 based on 2nd filter conditions (step A5 of FIG. 3). The conversion unit 115 is a circuit that discards data that does not satisfy the second filter condition in the received electronic message. The conversion unit generation unit 65 writes the circuit information of the conversion unit 115 to the conversion unit storage unit 53 of the storage device 50.

  The second filter condition is expressed by designating a subset of each field constituting the message. Therefore, the conversion unit generation unit 65 generates circuit information of a logic circuit that selects a specified field from the fields in the message as circuit information of the conversion unit 115.

  FIG. 9 is a block diagram illustrating an example of the configuration of the generated conversion unit 115. Referring to FIG. 9, the conversion unit 115 includes external input terminals city, temp, rain, external output terminals city, rain, and a field selection circuit 118.

  The field selection circuit 118 reads values from the external input terminals city, temp, and rain, and sends only the values of city and rain to the external output terminals city and rain, respectively. On the other hand, the field selection circuit 118 discards the value read from the external input terminal temp without sending it to the external output terminal.

  According to the conversion unit 115 shown in FIG. 9, only the values of the fields city and rain in the message are sent to the calculation processing unit 112, and the values of the other fields are discarded. That is, field data unnecessary for calculation processing is discarded, and only necessary data among data included in the electronic message is sent to the calculation processing unit 112.

  FIG. 10 illustrates an electronic message transmitted from the conversion unit 115 to the calculation processing unit 112. Comparing the message of FIG. 10 with the message of FIG. 8, the field temp in the message of FIG. 8 is discarded in the message of FIG.

  The conversion unit generation unit 65 records the circuit information of the conversion unit 115 in FIG. 9 in the conversion unit storage unit 53 of the storage device 50.

  The circuit information of the selection unit 114 stored in the selection unit storage unit 52 of the storage device 50 and the circuit information of the selection unit 115 stored in the conversion unit storage unit 53 are received using an existing circuit design technique. 111 and the calculation processing unit 112 are arranged in the message processing apparatus 107.

  The design support apparatus according to the present embodiment can be applied, for example, to design a message processing apparatus that processes real-time information (event sequence) from a sensor or a terminal.
