[Problem that the invention seeks to solve]

The conventional command processing method described above has the following problems.

(1) In the method shown in Figure 6, system path 4 is frequently used, resulting in large overhead time and deterioration of the overall system performance.

(Katana) In the method shown in Figure 7, it is necessary to register the command sequence to be executed in advance in the macro command storage memory 33, but the registration step has a limit and cannot satisfy various demands.

(3) In the method shown in FIG. 7, in order to solve the drawback in item 2, it is possible to change the contents of the macro command storage memory 33 every time a command is executed, but the macro command storage memory 33 is Since it exists inside the IP processor 3, when changing it, it is necessary to use a macro command storage memory setting command, and additional processing is required before issuing the command command.

(4) In the processing methods shown in FIGS. 6 and 7, it is not possible to perform order control such as repetition of processing, and it is necessary for the upper processing device to perform processing according to the user's needs.
There are limits to how sophisticated the commands can be.

[Means and operations for solving one problem] This invention provides a macro for storing standard command sequences that can be registered by the user; A macro command control memory is prepared to store the data of the macro command, and when a pre-registered command sequence execution command is given, the read address pointer of the macro command storage memory is transferred to the contents of the macro command control memory. Accordingly, the control is performed according to the contents of the Macro command control memory, and whether data read from the macro command storage memory is used or data set by the user in the external memory when the start command is generated is switched according to the contents of the Macro command control memory. It is intended to enable order control such as repetition of standard processing and processing using parameters determined at the time of command execution, and to achieve higher functionality, higher speed, and more diversification ◇ [Embodiment of the invention] fa1 The figure is a configuration diagram showing an embodiment of this invention, 1st AV4
1B is a configuration diagram showing the data structure stored in the stomach command control memory, FIG. 1B is a configuration diagram showing the types of control commands and their formats, and FIG. 1C is a configuration diagram showing 7 formats of switching parameters. .

As is clear from FIG. 1, in this embodiment, a macro command control memory 36 is provided in the image processing processor 3, a macro control memory pointer 35 which is a read pointer thereof is set, and a macro command control memory 36 is provided in the image processing processor 3. Read data from memory 36 to switch 37
Similarly, ■ is set as the control data of the macro command pointer 32, and the switch 37 transfers the data read from the common memory 2 and the read data from the macro command storage memory 33 to the macro command control memory 36.
The feature is that the switching is performed according to the read data (■) from.

In such a configuration, when the image processing processor 3 receives the processing command (2) from the processing device (1), the command processing is performed in the following steps.

(1) Load the processing command ■ into the command register axK. The upper data (2) is set to the macro command pointer 32, and the lower data (2) is set to the macro control memory pointer 35.

(2) Read the data in the macro command control memory 36 specified by the macro control memory pointer 35.

(3) The data read in section 1182 is
As shown in U, it is composed of a control command and a switching flag, and the control command becomes a control signal (2) for the macro command pointer 32, and the switching flag becomes a control signal (2) for the switch 37.

(4) For the three typical types of control instructions shown in Figure 1B, perform the processing in the following 5 for the 5KIP instruction, and the following 6 for the 5TEP and LOOP instructions.
Perform the following steps.

(g)) When it is a SKIP control command, the macro command pointer 32 is updated by the number of 5KIP, the macro control memory pointer 35 is +1, and #! Return to the process in Section 2.

(6) In the case of 8 T E P control command, set @l" in the loop number, and set the step number in the step number tank like #!IBIN (a). Also, in the case of LOOP control command, As shown in Figure 1B (c), set the loop break in the loop count tank, set the step number in the step count tank, and save the macro command pointer value.

Read the command specified by the macro command pointer 32 in the macro command storage memory 33 and update the macro command pointer 32 by +1 (8) Switch read from the macro command pointer memory 36 When the bit (0th bit) of 7 lags is OFF, the command read in item 'a7 is selected by the switch 37 and command processing is executed. On the other hand, O
When N is selected, data (2) from the buffer 22 of the common memory 2 is selected and processing is executed using this as a command (2).

(9) The switching flag is changed every time it is used.
It is shifted by it.

α [The parameters used when executing the command are also @7
- Lead according to the steps in section 9.

(11) When execution of one command ends, the number of steps is decreased by 1.

a2 When the number of steps is not 0, repeat the processing of items 87 to 11, and when the number of steps is 00, reduce the number of loops by 1.

If the number of loops is not 0, set the number of steps to the number of steps, and move the macro command pointer 32 to #! Return to the value saved in section 6, then t! Repeat the processes in Ii7 to 12. When the loop count is 00, the macro control pointer 35 is updated and the process returns to the second term.

a4 182”'13J] I t2) place 11Kg,
When the END (9 guns) command is executed, this command processing ends.

flK that actually forms a display screen using such a command processing procedure will be described below.

In FIG. 2, a command sequence for drawing a horizontal line is stored in the macro command storage memory 33 as shown in FIG.
This shows the situation when a 5TEP@ command with four steps as shown in J (b) is stored. In addition, as shown in FIG.
, C are the pointer set command, horizontal line drawing command, and pointer vertical movement command, respectively, and the verameters A, B, and C represent the pointer value (x8゜yl), horizontal line length (X2), and movement amount (y2), respectively. There is. Note that the FliND command is a command that ends command processing, and 5TEP4 indicates that four steps including this END command are executed. Therefore, when a command processing execution command is given from a higher-level processing device, the command A, B, and C are processed in this order, and as a result, a horizontal line XY as shown in FIG. 2A appears on the screen 5.
will be displayed. Figure 2A weight x1゜x2
p)'1 e It goes without saying that Y2 is specified by a parameter. Note that point P indicates the position of the pointer at the end of the command sequence.

FIG. 13 shows an example in which the memory 36KSPIP control command is set. Note that the contents of the memory 33 are the same as those shown in FIG. In this case, the number of skips is I4'' and the number of steps is '
Since it is "2" (STEP), the position where the top four of the memory 33 in FIG. 2 are skipped, that is, the command C
(command C and END command)
is executed.

Since command C is a pointer vertical movement command, in this case the pointer is moved from point po to point 21 as shown in FIG. 3A. The amount of movement is determined by the parameter C, which in this case is y2.

In addition,#! In the case of Figure 3, the switching parameter is @0″, so switching is not performed! Figure 4 is a case where the settings are rather complicated, and STgPIK

The buffer 22 of No. 2 contains the command D, and if this is a vertical line drawing command, a vertical line XY3 will be displayed on the screen 5 as shown in FIG. 5A.The parameters at this time are It is similar to FIG. 2 or FIG. 2A.

It should be noted that, although the above description has mainly focused on an image processing processor, it goes without saying that the present invention is applicable to general processing devices that perform similar processing.

〔Effect of the invention〕

According to this invention, since the read pointer of the macro command memory can be controlled using the macro command control memory, high-function commands such as repeating or executing only a part of the process can be executed using the minimum amount of the macro command control memory. can be easily created by the user by changing or adding
The advantage is that processing can be made more sophisticated and faster without adding any programs. In addition to the function of controlling the read address pointer, the user can select whether to receive parameters from the outside or read data from the registered macro command memory. This makes it possible to specify parameters by specifying parameters, thereby achieving the effect that it is possible to satisfy the various needs of users.
