Abstract

A program generating system which automatically rewrites a program using an individual'"'"'s language upon addition of an application-specific add-on board has a program generating device for generating a program using an individual'"'"'s language and a transformation data updating device for updating transformation data to generate updated transformation data for indicating rewriting the program upon addition of the application-specific add-on board. The program generating device transforms an initial document described in the individual'"'"'s language into a computer program according to a given role pattern and role assignment knowledge. The transformation data generated by the transformation data updating device modifies the role pattern and role assignment knowledge in the program generating device, and uses the same initial document as that used to generate the original program for a computer before the application-specific add-on board is added thereto, for generating a rewritten program as required by the addition of the application-specific add-on board.

Claims

1. A program generating system for rewriting an original program to accelerate execution of the original program by taking advantage of a dedicated application-specific add-on board designed to execute certain segments of a program in an efficient manner.

the program generating system comprising:

an original program comprising a computer-executable program generated by applying transformation data to an initial document, describing functions in a natural language, which solve a specific problem;

the transformation data including a set of role patterns, in a role tree format, indicative of the roles of each sub-unit of the original program and role assignment knowledge providing relationships between the patterns,

means for updating the transformation data to generate updated transformation data, having the role tree format, for rewriting the original program to take advantage of the application-specific add-on board, by partly changing the set of role patterns and role assignment knowledge related to the use of the application-specific add-on board; and

means for generating a rewritten program, which takes advantage of the application-specific add-on board, from the initial document using the updated transformation data.

2. A program generating system according to claim 1, wherein said means for updating the transformation data comprises:

transformation data holding means for holding all transformation data up to a given time;

updating transformation data input means for inputting transformation data used in rewriting the original program to take advantage of the application-specific add-on board; and

updated transformation data generating means for updating the transformation data held by said transformation data holding means with the transformation data inputted by said updating transformation data input means generating updated transformation data necessary to generate the rewritten program.

3. A program generating system according to claim 2, wherein said means for updating the transformation data further comprises:

means for applying the updated transformation data generated by said updated transformation data generating means to rewrite said original program, to a set of role tree transformation rules for the original program in a transformation process for specifying an implementation method for computation in said means for generating a program using the individual'"'"'s language, for thereby modifying the role tree transformation rules.

4. A program generating system according to claim 2, wherein said means for updating the transformation data further comprises:

means for applying updated expression generating data for rewriting the original program which are generated by said updated transformation data generating means, to a set of patterns and a vocabulary set for the original program in a linguistic description generating process in said means for generating a program using the individual'"'"'s language, for thereby adding a pattern and vocabulary.

5. A method of transforming an original program to take advantage of a dedicated application-specific add-on board which executes certain segments of a program in an efficient manner, the method comprising:

retrieving an initial document which describes functions of the original program, in a natural language, which solves a specific problem;

retrieving an original set of transformation data which specifies how to create the original program from the initial document the transformation data including a set of role patterns, in a role tree format, indicative of the roles of each sub-unit of the original program and role assignment knowledge providing relationships between the role patterns;

correcting the original set of transformation data to produce a set of updated transformation data required to produce a rewritten program from the initial document which takes advantage of the application specific add-on board by partly changing the set of role patterns and role assignment knowledge related to the use of the application-specific add-on board; and

generating the rewritten program from the initial document using the set of updated transformation data.

6. A method as in claim 5, further comprising:

generating the original program from the initial document based on the original set of transformation data.

7. A method as in claim 5, further comprising:

generating the initial document based on the original program.

8. A method as in claim 5, wherein the step of generating the rewritten program accesses a knowledge base.
