Abstract

PURPOSE:To revise data during use into not yet used data in response to an identification data open instruction and to manage the data used tentatively, by reading out the identification data of not yet used at a management section depending on an inputted identification data acquiring instruction and revising the data during the use. CONSTITUTION:The information whether or not a plurality of identification data are in use or not yet used data is managed at a managing section 101 and an operation section 102 is connected to the section 101 via a signal line 111. The managing section 101 is provided with demultiplexers 204 and 205 and a multiplexer 206, and a signal from a selector 211 selects the demultiplexers/ multiplexer 204-206. A readout/write signal 212 and an input data 213 are respectively applied to the demultiplexers 204 and 205 and a designation signal is inputted to a memory 203. The output of the registers 201, 202 and the memory 203 is applied to the multiplexer 206, an output data 214 is outputted and the management of the data used tentatively is performed at the management section 101.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data management device for managing identification data temporarily used in the process of processing in a computer.
-

In the process of processing in a computer, when a certain data processing step is decomposed, there are elements to identify the decomposed parts, such as names, and it is necessary to add names. Identification data added in this way has no meaning in itself, but is used temporarily to distinguish between different items, and often requires management to prevent duplicate use. 1. Conventionally, methods of managing using software have been known.

However, in the conventional method, saving memory increases the execution time of the management software, and if the memory is used up sufficiently, the valuable resource of processor address space is wasted, which brings about the inconvenience.

An object of the present invention is to provide a data management device that enables management of temporarily used identification data.

According to the present invention, for a plurality of pieces of identification data, there is provided a management unit that manages information fe indicating whether each piece of identification data is in use or unused; It is possible to obtain a data management device characterized by comprising an operation section that reads out identification data and makes it in use or makes unused identification data in use in the management section.

Hereinafter, the present invention will be explained in detail using figures.

FIG. 1 is a block diagram schematically showing a data management device of the present invention. In the figure, 101 is a management section, and 102 is an operation section.

The management unit 101 stores information on whether or not each piece of identification data is used for identification, and data is written and read through a signal line 111.

When the operation unit 102 receives an identification data acquisition command on the signal line 112, the operation unit 102 outputs unused identification data and data from the management unit 101 and makes the identification data in use.
When the identification data release command is received in step 12, a more specific embodiment of the present invention will be described in detail.

FIG. 2 is a block diagram showing the 1iF buried section of this embodiment. In the figure, 201.202 is a register, 203 is a mecha IJ, 204.205 is a demultiplexer, and 2o6
211 is a multiplexer, and 211 is a demultiplexer 204.
205 selector for multiplexer register, 212 read/write designation signal, 213 input data, 214 output data, 215 each address for memory 203, 2
16 and 217 are load signals for the registers 201 and 202, respectively; 218 is a continuous write designation signal for the memory 203; 219, 220, and 221 are input data for the register 201 and the memory 203, respectively;
2.223゜224 are each register 01.202
This is output data from memory 203.

This management section uses the address of the memo blade 203 as a storage for identification data, and uses the pointer structure to store unused identification data.
Understand. In other words, unused IIe data ■□I,...
, I, , (not necessarily in the order of values, but in accordance with G, memory 203 + 7) 1k (n > k > 1) +□ is stored in the hani ■ specified by the ink, and J4
, The register 201 stores the value ■, and the register 202 stores the value . The book is stored in the register 201 according to the selection of the selector 211. Register 202. Alternatively, the data may be distorted or distorted from the memory 203.

FIG. 3 does not show details of the operating section of this embodiment.

This is a diagram.

In the figure, the signals in the 200s are the same as in Figure 2, and 301 is 211.
゜311, 312.313.314.319 A microprogram controller that emits appropriate warnings,
302.303.304 are registers, 305 is a multiplexer, 306 is a register, 311.312.313.
319 is each register 302゜Ju3.304.3
Load signal for 06, 314 is multiplexer 3
Selector for 05, 315 is instruction ID number, 316,
317 is data, respectively.

This operation unit sends the command signal 315 to 6-i for acquiring identification data.
When k4-k'& is entered, the microblock controller 301 erases the signal train and operates as follows. The selector 211 selects the register 201 shown in FIG.
14 is loaded into the register 303 using the load signal 312, and the data on the signal 320 is loaded into the registers 304 and 306, respectively, using the load signal J13.319. At this point, data 317 is given unused identification data. Next, the selector 211 selects the memory 203 shown in FIG. 2, specifies the read convolution designation signal 212 as ωE output, and reads
Load data 214 into register: j0 with load signal 312
3) LO-to, selector 3] 4'C1g No. 32
0 is selected and the load signal: 3]1 is sent to the register 302 (i
Load the data on the f number 318, select the register 201 in FIG. 2 with the selector 211, and
The investment designation signal 212 is designated as convolution, and the data 213 is written into the second register 2)1. At this point, the management information of the identification data in the management section is updated.

When this operation section receives an instruction to release the identification data in the command signal 315 together with the identification data on the data 316, the microprogram controller 301 issues a signal sequence and operates as follows. The selector 211 selects data 316 and loads the released identification data into the register 302 with the load signal 311.
Select 02 and specify continuous output with read/write designation signal 2]2,
The read data 214 is loaded into the register 303 using the read signal 312, and the register 303 is loaded to the register using the load signal 313.
Select 3, specify writing with the read/write designation signal 212, and store the data 213 to the address specified by the data 215. Next, select all registers 202 in FIG. 2 with the selector 211, and use the read/write designation signal Specify writing with 212 and write data 2
Write 13. At this point, the management information of the identification data in the management section is updated.

The present invention has been explained above, but if the data management device of the present invention is used to manage identification data,
It is not necessary to separately prepare management software for each different TF computer, and therefore the burden on the programmer is reduced, and the valuable resource of the address space of the processor is not wasted.
