Abstract

PURPOSE:To efficiently process data with a tag by adding a tag generator for generating a previously determined tag based on the sort of operation. CONSTITUTION:Information indicating the sort of operation outputted from a controller 14 is inputted also to the tag generator 13 through an input terminal 15 in addition to an arithmetic unit 12. An operation decoding device 20 decodes inputted information and outputs the decoded information to a tag memory device 21 as a memory address storing a necessary tag. The device 21 storing a tag table generates the contents of the memory address applied from the device 20 as the tag of an operated result and transfers the tag to a proper tag register device 10 through an output terminal 16.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a data processing device mainly intended for use in the field of artificial intelligence.

BACKGROUND OF THE INVENTION In recent years, the field of artificial intelligence has been actively researched as one of computer applications. The LISP language is widely used in this field (for example, 1 -LIS
"P Machine" Information Processing Vol. 1.23. ]KrB, pl
), 752-772). In particular, tags that indicate the type of data are essential for the realization of LISP, and hardware-based sabots are also common (for example, "AI dedicated machine that deploys from a development machine to an execution machine with a processor LSI at its core" Nikkei) Electronics IEc412, pp
, 91 106).

An example of a conventional data processing device incorporating the above-mentioned tag will be described below with reference to the drawings.

FIG. 3 is a block diagram showing an example of -(-8j IJi) of a conventional data processing device.
1 is for each piece of data with its tag) < I
3 is a tag register Rf & deparue register device for storing J-Unit; 32 is an arithmetic device for executing value calculations;
This is a control device that controls the entire 3i. Each data is composed of a tag and a value, and when the control device 33 instructs an operation on the value, an appropriate value register device 31 is selected, and the arithmetic device 32 executes the instructed operation. Then, the tag of the calculation result is the tag register device 3o corresponding to the selected value register device 31.
According to the content of and the value of the calculation result, the control device 3
3 is decided.

However, even if the data type of the calculation result is known in advance, the tag for the calculation result must be determined again. Data processing devices have had the problem of being inefficient.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a data processing device that can efficiently generate tags with a simple configuration.

Means for Solving the Problems In order to solve the above problems, the data processing device of the present invention includes a tag generation device that generates tags, and generates the tag according to the type of operation to be performed on the value. The device generates a predetermined tag.

Effect of the Invention With the above-described configuration, the present invention automatically generates tags depending on the type of calculation, so there is no need to newly determine the tag of the calculation result, and it is possible to efficiently process tagged data. That's it.

Embodiment Hereinafter, a data processing apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the entire configuration of a data processing device in an embodiment of the present invention. In FIG. 1, 10 is a tag register device that stores data tags, 11 is a value register device that stores data values, 12 is an arithmetic device that performs calculations on the data values stored in the value register device 11; Reference numeral 13 designates a tag generator that generates a predetermined tag based on the type of calculation performed by the calculation device 12, and reference numeral 14 represents a control device that controls the entire system. The tag generator 13 has an input 16 for inputting the type of operation and an output 16 for outputting the generated tag. FIG. 2 is a block diagram showing the internal configuration of the tag generating device 13 in the above embodiment, where 2o is an arithmetic decoding device that decodes the type of arithmetic operation;
21 is a tag memory device that stores tags to be generated as a table.

The operation of the data processing apparatus configured as described above will be explained below with reference to FIGS. 1 and 2.

Each data is stored separately in the tag register device 1o and the value register device 11, and when performing an operation on the data, the control device 14 instructs the arithmetic device 12 to select the necessary value register device 11 and perform the operation. Indicates the type of The arithmetic unit 12 performs necessary arithmetic operations on the contents of the selected value register device 11 and transfers the results to the appropriate value register device 11. Information indicating the type of calculation output by the control device 14 is input not only to the calculation device 12 but also to the tag generation device 13 via the input 15. The arithmetic decoding device 20 decodes the input information and outputs it to the tag memory device 21 as a memory address storing the necessary tag. The tag memory bag cylinder 21 stores a table of tags, generates the contents of the memory address given from the arithmetic decoding device 20 as a tag of the arithmetic result, and transfers it to an appropriate tag register device 1o via the output 16. For example, integer and floating point number tags are printed for addition, subtraction, multiplication and division operations on integers and floating point numbers, and list tags and symbol atoms are printed for list generation operations such as list connection and list element deletion. The arithmetic decoding device 20 and the tag memory device 21 may be configured to generate a character string tag for a character string generation operation such as extracting a name or cutting out a substring from a character string.

As described above, according to this embodiment, tags for data calculation results can be efficiently obtained with a simple configuration.

Effects of the Invention As described above, the present invention provides a method for representing data using a tag indicating the type of data and a value indicating the value of the data. a plurality of value register devices, an arithmetic device that performs an operation on the value, a tag generator that generates the tag, and a control device that controls the entire device; Therefore, by having the tag generator generate a predetermined tag, a tag indicating the type of data resulting from the calculation is required at the same time as the calculation is performed on the value of the data. It is no longer necessary to determine the tagged data, and the excellent effect of efficiently processing tagged data can be obtained.
