In FIG. 1, the connection terminal 11, the storage unit 12, the determination unit 13, and the processing unit 14 are usually integrated. The term “integral” means, for example, being physically inseparable, being in one physically closed space, being configured on one electronic circuit board, and the like. .

  FIG. 2 is a block diagram of a computer system 9 that uses the memory module 1. 2, the computer system 9 includes a computer 901 including a CD-ROM drive 9011 and an FD drive 9012, a keyboard 902, a mouse 903, and a monitor 904. In addition to the CD-ROM drive 9011 and the FD drive 9012, the computer 901 is connected to an MPU 9013, a ROM 9014 for storing programs such as a bootup program, and an MPU 9013, and temporarily stores application program instructions. In addition, a RAM 9015 for providing a temporary storage space, a hard disk 9016 for storing application programs, system programs, and data, and a bus 9017 for interconnecting a CD-ROM drive 9011, an FD drive 9012, an MPU 9013, and the like Is provided. Although not shown here, the computer 901 may further include a network card that provides connection to a LAN. It should be noted that how the computer system 9 operates is well known and will not be described in detail.

  The memory module 1 in the present embodiment is usually provided in the computer system 9 of FIG. The memory module 1 is usually a main storage device such as the ROM 9014 and the RAM 9015 in FIG. 2, but may be an auxiliary storage device such as a hard disk 9016, for example. The memory module 1 may be a USB memory or a card type memory (not shown) called a so-called flash memory. The memory module 1 normally operates without external control such as an electronic circuit board to which the memory module 1 is connected and a computer system 9 including the memory module 1.

  The connection terminal 11 is a connection terminal for data transfer. Further, the connection terminal 11 usually conforms to a connection standard for data transfer. The connection standard for data transfer is, for example, DDR (including Double Data Rate, DDR2, DDR3, etc.), SATA (including Serial ATA, SATA2, SATA3, etc.), IDE (Integrated Drive Electronics), and the like. Further, the connection standard for data transfer does not normally include a connection standard used for purposes other than data transfer such as USB (Universal Serial Bus) and PC card, but may be considered to include it. The connection terminal 11 is usually a so-called male type, but may be a so-called female type.

  Data is written to the storage unit 12 from the outside via the connection terminal 11. The data written in the storage unit 12 is read from the outside via the connection terminal 11. The data stored in the storage unit 12 may be deleted as a result of being read from the outside via the connection terminal 11. Further, the format and capacity (size) of data stored in the storage unit 12 are not limited. For example, image data, video data, audio data, data of a predetermined capacity or more, data of a predetermined capacity or less are written in the storage unit 12.

  The determination unit 13 determines the attribute of data stored in the storage unit 12 or the state of the storage unit 12. “Data to be saved” is usually saved data. The “data attributes” include, for example, format, type, capacity, number of colors, size (dimensions), resolution, bit rate, music length, and the like. The “state” means, for example, that data is stored or that data is not stored. The “state” may include, for example, that data has been written, data has been read, data has been deleted, and the like.

  In other words, the determination unit 13 normally includes information indicating the attribute of data stored in the storage unit 12 (hereinafter referred to as data attribute information as appropriate) or information indicating the state of the storage unit 12 (hereinafter referred to as storage state information as appropriate). ) Is acquired from the storage unit 12 or from the storage unit 12, and whether the data attribute information or the storage state information satisfies a predetermined condition (hereinafter, processing start condition as appropriate). to decide. When the determination unit 13 determines that the data attribute information or the storage state information satisfies the processing start condition, the processing unit 14 described later determines the data stored in the storage unit 12 or the storage unit 12 with a predetermined value. Perform the process. Note that the processing start condition is normally held by the determination unit 13, but may be stored in a predetermined recording area or an arbitrary storage area. Further, “determining whether or not a predetermined condition is satisfied” means that a determination is made using a predetermined condition (processing start condition).

  Further, the process start condition is a condition for determining a timing (trigger) at which the processing unit 14 to be described later starts a predetermined process, or for determining an object to be processed by the processing unit 14 to be described later. . That is, the process start condition includes a timing condition for determining the timing for starting the process, a target condition for determining a target to be processed, and the like.

The timing conditions are, for example, the following conditions.
(A1) Data has been written to the storage unit 12 (A2) Data has been read from the storage unit 12 (A3) Data has been deleted from the storage unit 12

  (A1) may be, for example, data writing to a region where data is not stored (writing new data), or data writing (overwriting) to a region where data is already stored. May be. Further, (A2) may be, for example, erasing data from an area where data is already stored (erasing existing data). The timing condition may be, for example, “being a predetermined timing”. This condition means that the timing at which the processing unit 14 described later starts a predetermined process is regular.

  The target condition is, for example, a data attribute condition that is a condition related to the attribute of data stored in the storage unit 12, a storage state condition that is a condition related to the state of the storage unit 12, or the like. The data attribute condition is a condition related to data attribute information. The storage state condition is a condition related to storage state information.

The data attribute condition is, for example, the following condition.
(B1) The data format is a predetermined format (B2) The data capacity is a predetermined capacity

Moreover, the preservation | save state conditions are the following conditions, for example.
(C1) Data is stored in the storage unit 12 (C2) Data is not stored in the storage unit 12

  (B1) may be, for example, “a data format satisfies a predetermined condition”. Further, (B2) may be, for example, “the data capacity is equal to or greater than the threshold” or “the data capacity is equal to or less than the threshold”. Further, the data attribute condition may be, for example, “no matter what the data attribute is”.

  Further, the storage state condition may be, for example, “any state”.

  Further, the determination unit 13 normally determines whether or not the processing performed on the storage unit 12 satisfies the timing conditions (A1) to (A3) described above. When the determination unit 13 determines that the condition is satisfied, the attribute of the data stored in the storage unit 12 is the target condition (data attribute condition) such as (B1) or (B2) according to the determination result. And whether or not the state of the storage unit 12 satisfies the target conditions (storage state conditions) such as (C1) and (C2).

  For example, it is assumed that the determination unit 13 determines that the processing performed on the storage unit 12 satisfies the above (A1) (data has been written to the storage unit 12). Then, the determination unit 13 determines which of the data attribute conditions such as (B1) and (B2) satisfies the written data. At this time, the determination unit 13 may determine whether the state of the storage unit 12 after the writing satisfies the storage state condition such as (C1) or (C2).

  For example, it is assumed that the determination unit 13 determines that the process performed on the storage unit 12 satisfies the above (A3) (data has been deleted from the storage unit 12). Then, the determination unit 13 determines whether the state of the storage unit 12 after the deletion satisfies the storage state condition such as (C1) or (C2). At this time, the determination unit 13 may determine which of the data attribute conditions such as (B1) and (B2) the deleted data satisfies.

For example, the determination unit 13 may perform determination by combining any one of the timing conditions (A1) to (A3) and any one of the data attribute conditions (B1) and (B2). . For example, the processing start conditions when each of the above (A1) to (A3) and the above (B1) are combined are the following conditions.
(AB1) Data in a predetermined format is written in the storage unit 12 (AB2) Data in a predetermined format is read from the storage unit 12 (AB3) Data in a predetermined format is deleted from the storage unit 12 Was it

For example, the determination unit 13 may perform determination by combining any of the data attribute conditions such as (B1) and (B2) and the storage state condition such as (C1) and (C2). For example, the processing start conditions when the above (B1) and each of the above (C1) and (C2) are combined are the following conditions.
(BC1) Data in a predetermined format is stored in the storage unit 12 (BC2) Data in a predetermined format is not stored in the storage unit 12

  In addition, the determination unit 13 normally makes a determination using the above (AB1) and a determination using the above (C1) or (C2). When performing the determination using (AB1), for example, the determination unit 13 first performs the determination using (A1), and when it is determined that the data has been written, the data satisfies (B1). It may be determined whether or not. When the determination using (AB1) is performed, the determination unit 13 normally determines whether the data written in the storage unit 12 is image data. When performing the determination using (C1) or (C2), for example, the determination unit 13 periodically acquires storage state information from the storage unit 12, and the storage state information is the (C1) or (C2). It is determined whether or not C2) is satisfied.

  For example, it is assumed that the processing start condition is “image data, writing”. The process start condition includes a target condition (data attribute condition) “image data” and a timing condition “write”. In this case, for example, the determination unit 13 determines whether image data has been written in the storage unit 12. In this case, for example, the determination unit 13 determines whether or not data has been written in the storage unit 12, and when determining that the data has been written, the determination unit 13 also determines whether or not the data is image data. Good.

  In addition, for example, it is assumed that the processing start condition is “stored data, none”. The processing start condition is a storage state condition. In this case, the determination unit 13 determines whether data is stored in the storage unit 12, for example. In this case, for example, the determination unit 13 determines whether or not the predetermined timing is reached, and determines whether or not data is stored in the storage unit 12 when it is determined that the predetermined timing is reached. May be.

  The processing unit 14 performs predetermined processing on the data stored in the storage unit 12 or the storage unit 12 according to the determination result by the determination unit 13.

  For example, it is assumed that the determination unit 13 performs determination using the above (A1), (B1), and the like and determines that data satisfying a predetermined condition is written in the storage unit 12. In this case, for example, the processing unit 14 performs a predetermined process on the written data. The predetermined processing is, for example, image processing when the written data is image data. In addition, the predetermined processing is audio processing when the written data is audio data. In addition, the predetermined processing is processing according to another format when the written data is data in another format. The image processing includes, for example, noise removal, high resolution, high image quality, and the like. The audio processing includes, for example, noise removal, sound volume averaging, and high sound quality. That is, the predetermined process performed on the written data is usually a process for improving the written data.

  Further, for example, it is assumed that the determination unit 13 makes a determination using the above (C1) and (C2) and determines that no data is stored in the storage unit 12. In this case, the processing unit 14 usually initializes the storage unit 12. The initialization includes, for example, reset, complete erasure, and zero clear. The initialization may include, for example, memory compaction and defragmentation. That is, the process performed on the storage unit 12 is usually a process for organizing the storage unit 12.

  When performing a predetermined process on the data stored in the storage unit 12, the processing unit 14 usually reads the data, performs the predetermined process on the data, and stores the data of the processing result. To the storage unit 12. At this time, the processing unit 14 normally overwrites the written data (read data).

  In addition, for example, if the written data is not stored in the storage unit 12 when the processing result data is written, the processing unit 14 does not normally write the processing result data to the storage unit 12. Further, for example, when the read data is erased from the storage unit 12, the processing unit 14 may stop a predetermined process for the read data.

  Moreover, the process part 14 hold | maintains the process content information which is the information which shows the content of said process, for example, and may perform the said process using the said process content information. The processing content information is, for example, an instruction indicating a method or procedure of processing (operation) to be performed, a program, a program identifier, or the like. In this case, the processing unit 14 performs processing according to an instruction indicated by the processing content information, or executes a program that is processing content information.

  The memory module 1 may store, for example, one or more process management information, which is information in which process start conditions are associated with process content information, in a predetermined storage area or an arbitrary storage area. . The predetermined storage area may be a process management information storage unit (not shown) in which process management information is stored. In this case, the determination unit 13 and the processing unit 14 normally use the processing management information to determine the data stored in the storage unit 12, determine the storage unit 12, and store the data stored in the storage unit 12. The process for the storage unit 12 is performed. That is, the determination unit 13 determines which of the processing start conditions included in the one or more pieces of processing management information satisfies the attribute of the data stored in the storage unit 12, the state of the storage unit 12, and the like. Then, the determination unit 13 acquires process content information corresponding to the process start condition determined to be satisfied from a predetermined storage area. Then, the processing unit 14 performs a predetermined process according to the processing content information acquired by the determination unit 13. Moreover, when using process management information, the determination part 13 may perform the determination according to the process start conditions which the said process management information has. For example, when the processing start condition is “image data, writing”, the determination unit 13 determines whether image data has been written in the storage unit 12. For example, when the processing start condition is “stored data, none”, the determination unit 13 determines whether data is stored in the storage unit 12.

  The storage unit 12 can be realized by a volatile recording medium, a non-volatile recording medium, or the like.

  In addition, the determination unit 13 and the processing unit 14 can be usually realized by an MPU, a memory, other hardware (dedicated circuit), or the like. Further, the processing procedure of the determination unit 13 or the like may be realized by software, for example, and in this case, the software is recorded on a recording medium such as a ROM.

  Next, the overall operation of the memory module 1 will be described with reference to the flowchart of FIG. Note that the i-th information in the predetermined information is described as “information [i]”.

(Concrete example)
Next, a specific example of the operation of the memory module 1 will be described.

(Example 1)
In this example, the memory module 1 is assumed to be a main memory in a so-called computer. Further, the determination unit 13 performs a predetermined determination on the data stored in the storage unit 12 or the storage unit 12. The processing unit 14 performs predetermined processing on the data stored in the storage unit 12 or the storage unit 12 according to the determination result of the determination unit 13.

  First, it is assumed that one image data is written in the storage unit 12 as a result of the user operating the computer. At this time, it is assumed that the determination unit 13 periodically determines whether data has been written to the storage unit 12. Then, the determination unit 13 determines that data has been written in the storage unit 12. Then, the determination unit 13 acquires the attribute of the data from the data written in the storage unit 12, and determines that the data is image data.

  Next, the processing unit 14 reads the image data written in the storage unit 12 from the storage unit 12 according to the determination result of the determination unit 13. Then, the processing unit 14 performs noise removal processing on the image data, and obtains image data from which noise has been removed (hereinafter, image data after noise removal).

  Next, the processing unit 14 determines whether the read image data (hereinafter referred to as original image data) is still stored in the storage unit 12. Here, it is assumed that the processing unit 14 determines that the original image data is still stored in the storage unit 12. Then, the processing unit 14 overwrites the original image data with the acquired noise-removed image data. As a result, the noise-removed image data is written in the area where the original image data is stored in the storage unit 12.

  Next, it is assumed that the original image data is deleted from the storage unit 12 as a result of the user operating the computer. At this time, it is assumed that the determination unit 13 periodically determines whether one or more pieces of data are stored in the storage unit 12. As a result of the determination, it is assumed that the determination unit 13 determines that one or more pieces of data are not stored in the storage unit 12.

  Next, the processing unit 14 initializes the storage unit 12 according to the determination result of the determination unit 13.

(Example 2)
In this example, the memory module 1 is assumed to be, for example, a card-type memory (hereinafter referred to as a memory card). Further, it is assumed that the processing management information shown in FIG. 5 is stored in a predetermined storage area of the memory module 1. The process management information includes an ID (item name: ID) for uniquely identifying a record, a process start condition (item name: condition), and process content information (item name: process). In addition, the determination unit 13 determines whether the attribute stored in the storage unit 12 or the state of the storage unit 12 satisfies a process start condition included in the process management information. It is assumed that processing content information corresponding to the start condition is acquired. The processing unit 14 performs processing indicated by the processing content information using the processing content information acquired by the determination unit 13.

  First, similarly to Example 1, it is assumed that one image data is written in the storage unit 12 as a result of the user operating the computer. Then, the determination unit 13 acquires the attribute of the data from the written data and acquires “image data”.

  Next, the determination unit 13 determines which of the processing start conditions in FIG. 5 satisfies whether the data is written in the storage unit 12 and that the data is image data. As a result, the determination unit 13 determines that the data has been written to the storage unit 12 and that the data is image data, that the processing start condition “image data, write” of “ID = 011” in FIG. Judge that it satisfies. Then, the determination unit 13 acquires the processing content information “image data, noise removal” of “ID = 011” in FIG. The processing content information means that noise removal processing is performed on the written image data.

  Next, the processing unit 14 reads out the image data written in the storage unit 12 from the storage unit 12 in accordance with the processing content information “image data, noise removal” acquired by the determination unit 13. Then, the processing unit 14 performs noise removal processing on the image data in accordance with the processing content information, and acquires noise-removed image data.

  Note that the processing such as the writing of the noise-removed image data acquired by the processing unit 14 to the storage unit 12 is the same as that in Example 1, and thus the description thereof is omitted.

  Next, as in Example 1, it is assumed that the original image data is deleted from the storage unit 12 as a result of the user operating the computer. It is assumed that no data is stored in the storage unit 12 as a result of the deletion. Then, the determination unit 13 acquires the state of the storage unit 12 and acquires “no data”.

  Next, the determination unit 13 determines which of the processing start conditions in FIG. 5 satisfies that the data is not stored in the storage unit 12. As a result, the determination unit 13 determines that the fact that no data is stored in the storage unit 12 satisfies the processing start condition “data, none” of “ID = 013” in FIG. Then, the determination unit 13 acquires the processing content information “initialization” of “ID = 013” in FIG. The processing content information means that the storage unit 12 is initialized.

  Next, the processing unit 14 initializes the storage unit 12 in accordance with the processing content information “initialization” acquired by the determination unit 13.

(Example 3)
6 and 7 are image diagrams showing a conventional function expansion method for an electronic circuit board. In the conventional function expansion method, an expansion module for function expansion is set (connected) to an electronic circuit board. However, in the conventional function expansion method, as shown in FIGS. 6 and 7, the expansion module cannot be set unless an expansion slot for setting the expansion module is provided. If you have it, you can set an expansion module, but that's an extra cost.

  However, for example, as shown in FIG. 8, the data processing circuit included in the expansion module shown in FIGS. 6 and 7 is mounted on the memory module, so that the function can be expanded using an existing structure such as a memory slot. it can. The memory module of FIG. 8 includes a memory similar to the memory modules of FIGS. 6 and 7, and performs the same operation as the conventional memory module. In addition, the data processing circuit included in the memory module of FIG. 8 operates asynchronously with the electronic circuit board (hereinafter referred to as a board or a system as appropriate) with respect to data written in the memory. The operation as an expansion module can be performed without affecting the function.

  FIG. 9 is a diagram illustrating a memory module 2 that is a circuit configuration example of the memory module 1. The memory module 2 includes two or more memories 21, a switch 22 that switches connection between the two or more memories 21 and the memory controller 23, a memory controller 23, a data type identification circuit 24, and an image noise removal circuit 25.

  The two or more memories 21, the switch 22, and the memory controller 23 correspond to the storage unit 12. The data type identification circuit 24 corresponds to the determination unit 13. The image noise removal circuit 25 corresponds to the processing unit 14.

  In FIG. 9, the image noise removal circuit 25 performs a noise removal process on data stored in the memory 21 that has not received a request from the system side via the memory controller. As a result, data can be written and read from the system side as in the conventional memory module.

  The data type identification circuit 24 reads data on the memory via the memory controller and determines the type of data. If the read data is image data, the data type identification circuit 24 transmits the address of the image data on the memory and the processing request signal to the image noise removal circuit 25.

  When the image noise removal circuit 25 receives the address and the processing request signal from the data type identification circuit 24, the image noise removal circuit 25 reads out the image data at the address in the memory via the memory controller. Then, the image noise removal circuit 25 performs noise removal processing on the read image data, and obtains noise-removed image data. Then, the image noise removing circuit 25 overwrites the noise-removed image data at the address location on the memory via the memory controller.

  As described above, according to the memory module 1 according to the present embodiment, it is possible to perform predetermined processing on the written data. Thereby, for example, the functions of the electronic circuit board can be expanded without recreating the electronic circuit board.

  In each of the above embodiments, each component may be configured by dedicated hardware, or a component that can be realized by software may be realized by executing a program. For example, each component can be realized by a program execution unit such as a CPU reading and executing a software program recorded on a recording medium such as a hard disk or a semiconductor memory.

  The present invention is not limited to the above-described embodiments, and various modifications are possible, and it goes without saying that these are also included in the scope of the present invention.

  As described above, the memory module according to the present invention can perform predetermined processing on the written data. Accordingly, for example, the function of the electronic circuit board can be expanded without recreating the electronic circuit board, which is useful as an SDRAM or the like.
