Abstract

PURPOSE:To eliminate necessity to use an external memory, to reduce the burden of a high order program and to improve the processing efficiency of a system by once storing data, which are just processed, into a buffer module, fetching the data again out of the buffer module after exchange processing is finished and continuing the processing. CONSTITUTION:A program 6 is divided into the module per processing function to include an input system, an output system, a processing system and a buffer module to save the data. A processing information table 5 is provided to store processing information 50, which show the processing order of the module, with distinguishing the information to a module 51 for initial load and a module 52 for exchange. A control module 1 is provided to refer the processing information, to execute the load or exchange of the program module 6 to processors 2, 3 and 4 and to store the data on the processor into the buffer module when the program module 6 is exchanged. Thus, it is not necessary to execute the exchange of the program through the external memory and the processing efficiency can be improved as the system.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a program control system, and in particular, a control system for a pipeline processor system combining data flow pipeline processors [Prior Art] Conventionally, this type of control system has been developed. When performing a series of multiple processes, the processor system control system creates a program for each processing function and replaces and executes the program on the processor each time. was done via external memory.

[Problems to be Solved by the Invention] In the conventional control method described above, it is necessary to create a program for each processing function and replace the program on the processor each time it is executed. Since sending and receiving is done via external memory,
This has the drawback that the control of the host program that manages program replacement and external memory is complicated, and the processing efficiency of the system is low.

[Means for Solving the Problems] In the pipeline processor control method of the present invention, a program is divided into modules for each processing function including an input system, an output system, a processing system, and a buffer module for saving data, Loading or replacing a program module to a processor is performed by referring to a processing information table in which processing information indicating the processing order of the module is stored separately for an initial load module and a replacement module, and the processing information. The controller has a control module that stores data on the processor in the buffer module when the block module is replaced.

[The action control module refers to the processing information of the program modules and sequentially loads the modules onto the processor, and if it is necessary to replace the program modules on the processor, the data on the processor is temporarily stored in the buffer module.] Therefore, there is no need to send and receive data between processors via external memory.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a pipeline processor system to which an embodiment of the pipeline processor control method of the present invention is applied, and FIG. 2 is a diagram showing an example of the operation of this embodiment.

The pipeline processor system of this embodiment includes processors 1 to 4, and has a processing information table 5 that stores processing information 50 of a program module group 6 that constitutes a program. The processing information 50 includes an initial rotary module 51 and a major replacement module 52, and the processing function and pointer on the program module group 6 of each corresponding program module are recorded. The program module group 6 includes a data input and output system module, various processing system modules, and a buffer module for saving data. In addition, the control module of the processor 1''2 controls the entire program, refers to the table of the corresponding program in the processing information table 5 when executing the program, loads or replaces the program module to the bromo sensor, and further processes the program. When replacing modules, the data on the processor is stored in the buffer module, and processing is continued after the replacement is completed.

Next, the operation of this embodiment will be explained using character processing as an example.

Here, consider the following module as a program module.

1) Input system module: reads character patterns from a dedicated memory that stores character patterns.

2) Buffer module: Saves character patterns when randomly importing character patterns or when replacing modules during processing.

3) Processing system module: Density conversion of basic character system or density conversion of expansion system.

4) Output system module: Performs character expansion to output memory.

1. In Fig. 2, if we consider the vertical writing processing and cut-out processing of characters, in this case the character pattern is imported from the dedicated memory and character development is performed according to the vertical writing or predetermined cutting, so the second As shown in FIG. 1, an input system module and an output system module are respectively loaded into the processor 2.3 by the control module.

In addition, when vertical writing processing or cutting processing is performed after density conversion of the basic character system in the processing shown in Fig. 2 (1), input system module and output system as shown in Fig. 2 (2). In addition to the modules, processing system modules that perform density conversion of basic character systems are loaded into the processors 2, 3, and 3, respectively.

Furthermore, when performing basic character density conversion, followed by expansion system density conversion, and vertical writing processing or cutting processing, in this embodiment, except for processor 1 loaded with the control module, the actual Since there are three processors that execute the program at the same time, it is necessary to replace the modules in the processors, as shown in FIG. 2 (3). In this case, first, the input system module, the processing module that performs basic character system density conversion, and the buffer module each have a processor 2.3.4.
The character pattern loaded into the buffer module and subjected to density conversion is stored in the buffer module. Then, the modules are replaced, and the buffer module, the processing module that performs the expansion system density conversion, and the output system module are loaded into the processor 2.3.4, respectively. Thereafter, the character pattern is taken out from the buffer module, enlarged density conversion is performed, and finally the output module outputs the data to the output memory, thereby completing the process.

[Effects of the Invention] As explained above, the present invention records the processing order of modules into which a program is divided in the processing information table,
Refer to the information in the control module, load the modules into the processor sequentially, execute the program,
In addition, when it is necessary to replace the module, the data being processed is temporarily stored in the buffer module, and after the replacement is completed, the data is retrieved from the buffer module again and processing is continued, thereby saving external memory during data transfer between processors. There is no need to use it, the burden on the upper block is reduced, and the processing efficiency of the system is improved.
