Abstract

PURPOSE:To store a large quantity of dot data with a buffer memory of small capacity by reconfigurating a one-word/n-bit buffer memory into a one-word/one- bit buffer memory. CONSTITUTION:The X and Y axis data of one-word/n-bit configuration are stored successively to a memory means 191 via an A/D converter 13. A dot data producing means 192 reconfigurates the Y axis data stored in a Y axis memory addrrss corresponding to an X axis memory address storing the contents of the same X axis data into a one-word/one-bit configuration. The output of the means 192 is supplied to a graphic dot printer 33. Then the dot is recorded at the corresponding position decided by the X and Y axis scales and in response to the X and Y axis inputs.

In the figure, reference numeral 11 denotes an input switching means, such as a multiplexer, which alternately and sequentially switches analog human input signals S1 and analog input signals S2 such as voltage and current as X-axis inputs and X-axis inputs, respectively, and outputs them in time series.

The data is converted into a digital value of n bits, for example, 8 bits per word, and is sequentially applied to the input port 27 of the arithmetic unit 19 as an X data signal Ss and a Y axis data signal S4. Note that if an A/D converter for the X-axis input and an A/D converter for the X-axis input are separately provided, the input switching means 1
Additional multiplexers are no longer required.

Based on the dot data stored in the file memory, input waveforms and the like are recorded by marking dots at corresponding positions determined by the X-axis scale and Y-axis scale of the recording paper.

Next, the operation of the embodiment of the present invention will be explained.

Figures 3 and 4 show the storage of X-axis data and Y-axis data.
3 is a flowchart of a door l data generation processing program. Executed by steps P, ~R8, P1 ~ P1
．． In steps B and B, X-axis data and Y-axis data are stored in the X-axis memory and Y-axis memory, respectively, and in steps B to Psi, don't data is generated and printed.

First, at P1 in the figure, the first address of the first chapter of the X-axis Duke, which is the X-axis memory of the RAM 25, is set.

Set the starting address of the Y-axis data storage which becomes the Y-axis memory of the RAM 25.

At step b, it is determined whether the reference clock for storing X-axis data and Y-axis data in time series has risen. In the case of NO, it is repeatedly determined whether the standard black and white edges are rising or falling. Y
In case of ES, go to &.

In P9, input the X-axis data.

At P, the X-axis data is stored at the address of the X-axis memory.

Input the Y-axis data using PG.

In the crow, store the Y-axis data at the address of the Y-axis memory.

Increment the X-axis data address with Ps.

Increment the Y-axis data address using Karasu.

At Bo, it is determined whether the X-axis data address has reached the final X-axis data address. In the case of No, the process returns to step b and repeats steps 3 to 4 until the final address of the X-axis data is reached. If YES, go to Pn.

At B, set variable X to O.

Clear the buffer memory of RAM25 using Karasu.

& sets the start address of the χ-axis memory for reading the X-axis data.

At P, it is determined whether the contents of the X-axis data address and X are equal. If No, go to Bq and increment the X-axis data address.

Next, it is determined whether the X-axis data address is currently larger than the final X-axis data address. If NO, return to ]R4,
P1 until the content of the X-axis data address is equal to X.
7. Repeat each step of Pl.

If YES, go to PIG.

PIG reads the contents of the Y-axis data address that corresponds chronologically to the X-axis data address.

Since the Y-axis memory stores 8 bits per word in dot configuration, it is necessary to mark one dot corresponding to the contents of this Y-axis data during recording, and a buffer memory that stores the dot data for this purpose is required. In order to reduce the storage space, each word is stored in one bit, with each word being re-encoded.

To this end, in B6, the contents of the Y-axis data address are divided by 8 to calculate the quotient A.

Next, calculate the remainder N by dividing the contents of the Y-axis data address by 8 using Bq.

Next, with Bq, read the Nth bit from the LSB (least significant bit) of the address that is the start address of the buffer memory plus A.
The dot data is stored by converting from 0" level to 1" level. When there is not much available, the MSB (
The maximum B, G) is set to level 1.

In addition, in PIG~P1t, the contents of the Y-axis data are divided by 8 to calculate the quotient A and the remainder N, and the merchant and the remainder N are calculated.
From then, the Y-axis data is 1 word 1 bit.

However, dividing the contents of the Y-axis data by 8 is because the buffer memory was originally configured with 8 bits per word.
One word is 8 bits, and each word has a capacity of 62 bytes (62 words) to store the total amount of information of the configuration.
To reconfigure it into 8 bits, 7 bits, 111f
This is because it is appropriate to divide the bytes into 1 and select the corresponding 1 bit and 1 from the bytes.

In this way, all the X-axis memory addresses where the X-axis data is 0 are searched for from B4 to P, and if found, the Y-axis data at the same address as the X-axis memory address is searched. Each of the data is reconfigured into one word and stored in the memory (buffed as bit data). If there is none, it will disappear.

8, for each variable x = O that constitutes the contents of the X-axis data, the bit data of the FA memory is output to the graphics card printer 3 in order from the first address.

At P22, the variable X is set to X''-1.

At L, it is determined whether the variable X is greater than 255. If no, go to Mr. and clear the buffer memory. For the X-axis data content 1, perform step-pH step again, and repeat the same process until the X-axis data content reaches 255 for the horse. In addition, in the case of 1 word 8 bit configuration, the variable X that makes up the contents of the
Treated as 56.

FIG. 5 is a diagram showing an example of storing bit data in a buffer memory. In the figure, the hatched bits are the bits stored in the buffer memory when the contents of the X-axis data address x = 0 and the contents of the chronologically corresponding Y-axis data address are 10.21 and 0. It is data.

When taking out as a record, the paper feed direction of the graphic dot printer 3 is unidirectional, so if the paper feed direction is set to the X axis, the X axis data will be 25 in order from 0.
There are 256 lines (X-axis scale) up to 5. At this time, each time the line is changed, the contents of the buffered bit data are outputted to the graphic, dot, and dot printer, and the bits are recorded at the corresponding points on the Y-axis scale.

Effects of the Invention Since the X-Y recorder of the present invention has the configuration described below, the buffer memory having a 1-word n-bit structure can be reconfigured into 1-word 1-bit structure.

Even if the capacity of the buffer memory is small, a large amount of bit data can be stored.
axis memory, -Y axis memory] (The remaining memory of AM can be used, or a separate small memory can be used. Also, in the case of multi-channel, channel 1-) can be used as x +ll+ll If set above, multiple Y-axis channels can be performed at the same time.
