Abstract

(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention develops pattern data such as one character or symbol into a two-dimensional memory as two-dimensional data, and outputs it as display data and print data from the two-dimensional memory. This relates to an output control method when

Document creation devices such as word processors, whose scope of use has been rapidly expanding recently, use character generators (hereinafter referred to as C) that generate pattern data such as single characters and symbols.
A method is used in which predetermined pattern data is extracted from a file (referred to as G), target data is created, and this is temporarily stored in a two-dimensional memory or the like.

This stored data is read from a two-dimensional memory or the like and displayed on a display or printed with a printer depending on the purpose of use. Further, data displayed on a display or printed by a printer can be enlarged/reduced depending on the purpose, but it is desired that such data be created and output quickly.

[Conventional technology]

FIG. 2 is a block diagram when CG output data is developed into a two-dimensional memory using the conventional method.

FIG. 3 shows each method for developing two-dimensional data.

The development of the output data of the CG2 into the memory 4 is all controlled by the firmware of the microphone 1 coprocessor 7 (hereinafter referred to as MPtl) 1.

For example, the memory 4 that expands the alphabetic characters rAJ shown in FIG.
Expand to.

Note that the frame a is determined by the CG recessed frame control signal ■ from the MPUI.

When the MPUI is to expand into the memory 4, the bit position in the memory 4 is determined by the X-axis address signal (■) and the Y-axis address signal (■), and is expanded in bit units. At this time, if you want to enlarge the pattern data by a factor of 4, for example, use the enlargement/reduction control signal ■ from MPIJI.

Data is stored in a state in which portions b and b', which are automatically added with 3 bits at the determined focus position as shown in FIG. 3(B), are connected.

Note that the diagonally shaded portions of portions b and b' shown in FIG. 3(B) are the initially determined bits, and the white portions represent the added portions.

Moreover, FIG. 3(C) shows the state in which rAJ is developed in the memory 4 by such a method. That is, when pattern data is enlarged, the data has an uneven appearance.

Therefore, when formatting data with uneven appearance,
The smoothing signal (2) from MPtll is used to compensate for the unevenness caused by the enlargement.

In this way, the data developed in the memory 4 is read by the memory reading circuit 5, and output is controlled by the output control circuit 6 to, for example, a printer (not shown) and printed.

[Problem that the invention seeks to solve]

The pattern data from CG2 is expanded into the memory 4 using the method described above, but since the 1118 involved in this expansion is controlled by the MPtll firmware as described above, when various control signals are expanded together, the memory The MPU determines whether or not to apply various control signals for each bit on 4.
There was a problem in that it took a considerable amount of time to deploy because it was deployed while querying I.

[Means for solving problems]

The present invention aims to realize a novel two-dimensional memory output control method that solves the above problems.
The problem lies in the amount of data expanded in the two-dimensional memory, the data frame occupied in the two-dimensional memory, and the two-dimensional control memory that stores management data, including data indicating the rate at which data is expanded or contracted. The problem is solved by the two-dimensional memory output control method according to the present invention, in which the output of the two-dimensional memory is controlled by the output of the two-dimensional memory for controlling ν.

[Effect]

That is, the pattern data output by the CG is developed into a two-dimensional memory dedicated to data, the control data is developed into a two-dimensional memory dedicated to control data, and the data is read from both of the two-dimensional memories and sent to a display device or a printer device. When outputting data to a computer, data expansion/reduction and smoothing processing are controlled by hardware circuits such as registers, memory (RAM), and multiplexers, so that output data can be obtained quickly.

〔Example〕

The gist of the present invention will be specifically explained below with reference to an embodiment shown in FIG.

FIG. 1 shows an embodiment of the two-dimensional memory output control method according to the present invention; (A) is a block diagram of the device;
(B) shows a block diagram of the output control circuit. The same symbols refer to the same objects or contents throughout the design.

The pattern data generated from CG2 is stored in memory 4.
The data is developed within a predetermined frame a under the control of the axis address signal (2), the Y-axis address signal (2), and the CC write frame control signal (2).

On the other hand, the control data for the CC writing frame control signal (2) and the enlargement/reduction control signal (2) are expanded in the memory 8 in the same way. Nao C
All "1" data, which is black data (data with data), is written in the frame a defined by the C write frame control signal ■.

The control data of the memory 8 is read by the memory read circuit 9 and output to the output control circuit 10. Similarly, the data in the memory 4 is read out by the memory reading circuit 5 and output to the output control circuit 10.

Data from the memory read circuit 5 is sequentially stored in a shift register 11 composed of five elements having a storage capacity of 5 bits, and is swept out to the register 12 in units of 5 bits. On the other hand, a memory (RAM) 13 writes and stores all the data stored in the shift register 11 (ie, 25-bit data).

Next, if the data to be output from the memory readout circuit 9 to a display device, printer device, etc. (not shown) does not have enlargement/l1ii small, the data from the register 12 is output as is.

If the data requires enlargement processing, for example.

The output of the memory readout circuit 9 instructs the enlargement processing part in bit units. At this time, the data acquisition from the register 12 is switched to the data acquisition of the memory (RAM) 13, and the simulator including the relationship with the bits before and after 1 is changed. At the same time, smoothing processing is performed based on the smoothing data stored in the control unit 14, and shaped data with no irregularities in appearance is output.

〔Effect of the invention〕

According to the present invention as described above, there is an effect that processing of data output from a two-dimensional memory can be quickly controlled.
