Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing apparatus comprising input means for inputting data, data processing means for processing the input data, and output means for outputting the processed data. For example, the present invention relates to a data processing device that executes predetermined processing such as calculation and editing processing on image data, audio data, and other measurement data.

[0002]

2. Description of the Related Art In this type of data processing apparatus, a plurality of types of data, for example, data having different data lengths such as 8-bit data and 16-bit data, and data types such as decimal type data and integer type data, Similar processing needs to be performed on different data. This is because the hardware resources are used universally. Therefore, the conventional data processing device is configured to include a data processing unit composed of a plurality of software and a single hardware, and selects the software according to the type of data to be processed and processes the data. In some cases, the input data format is provided with a conversion means for converting the format of the input data into an intermediate format, a single software corresponding to the intermediate format, and a data processing means composed of a single hardware.

[0003]

However, the above-mentioned prior art has the following drawbacks. In the former, the data processing means is configured by creating a plurality of software that performs a predetermined process corresponding to the type of data as a library, storing it in a storage device, and combining the libraries corresponding to the type of data to be handled. The edited software cannot handle other types of data because it was edited as software for editing. That is, since it has no versatility, it has a drawback that it requires a long time to edit and create software suitable for each data type, and that the created software resources become huge and the management work becomes difficult. there were. In the latter case, the software that constitutes the data processing means becomes one type, and it is possible to secure versatility, but it takes a long time to convert the input data into one kind of intermediate format, for example, a floating point format, by the conversion means. It requires a long conversion time, a separate storage means for storing the converted data, and the need to reverse-convert the processed data to the original format if necessary. There was a flaw. Further, both need to design software while paying attention to the type of data, which requires sufficient attention to handle the data, which is a drawback that the designer is fatigued. . An object of the present invention is to eliminate the above-mentioned conventional drawbacks.

[0004]

In order to achieve this object, the data processing apparatus according to the present invention is characterized in that the data processing means is provided with a processing function for performing a predetermined processing on the data corresponding to the data type. Storage means provided with the input data, identification means for identifying the attribute data for identifying the type of the data provided in the input data, and data identified by the identification means among the processing functions stored in the storage means It is configured to include an execution unit that executes a processing function corresponding to the type. It is preferable that the execution unit includes an address generation unit that generates an address table indicating a start address of a processing function corresponding to the data type stored in the storage unit.

[0005]

A series of unit processes such as a predetermined process for data, for example, a display process on a display as an output unit, a writing process to a disk, and a data length conversion process are stored in the storage unit as a processing function. Each processing function is provided according to the data type. The identification means identifies the type of data, that is, the data length or the data type, from the attribute data attached to the input data. The executing means selects and executes a processing function that corresponds to a specific processing from the processing functions and that corresponds to the data type identified by the identifying means. In order to select the processing function, the address generation means for generating the address table indicating the start address of the storage address of the processing function corresponding to the data type stored in the storage means based on the data type identified by the identification means. Is provided and the corresponding processing can be executed by referring to the address table. For example, the processing can be executed by setting the address in the program counter. Therefore,
Once the processing function is created, the designer of the software of the data processing means can easily design the desired software without being conscious of the data type because it can be used universally without depending on the data type. By using the software, it is possible to automatically perform a predetermined process regardless of the data type.

[0006]

Therefore, according to the present invention, it is not necessary to edit the software suitable for each data type for a long time, and the software can be designed without being aware of the data type. Never get tired of. The created software resource is highly versatile, and its management work is small, and because it does not depend on the data type, it is easy. It is not necessary to convert input data into an intermediate format for a long time at all, and it is not necessary to increase the storage capacity therefor, so that it is possible to provide a data processing device having excellent processing efficiency.
