Program Code Generation Support Device and Method, Program Execution Device and Method, and Program Code Compression Processing Device and Method and Program Thereof

A program code generation support method comprising the steps of:

• analyzing a generated program code in analysis means;
• searching for a part matching a conversion condition in a program code while condition search means collates data of the conversion condition for converting the program code which is stored in storage means with the analyzed program code;
• and
• generating data of a new program code while conversion means converts the part matching the conversion condition on the basis of the data of the conversion content stored in the storage means.

A program of a program code generation support method for causing a computer to execute the steps of:

• analyzing a generated program code;
• searching for a part matching a conversion condition in a program code by collating data of the conversion condition for converting the program code which is stored in storage means with the analyzed program code;
• and
• generating data of a new program code by converting the part matching the conversion condition on the basis of the data of the conversion content stored in the storage means.

A program execution device comprising:

• first storage means for storing data obtained by compressing a program code constituted by an execution code that is composed of process data used for an execution process and a command representing the execution process which are arranged in order;
• second storage means for temporarily storing the process data;
• type determination means for reading the data obtained by compressing the program code from the first storage means by a predetermined data amount each to determine whether or not the data contains the command, and storing the process data in the data in the second storage means when it is determined as the data which does not contain the command;
• code extension means for generating an execution code on the basis of the process data stored in the second storage means and the command when the type determination means determines that the data contains the command;
• and
• execution means for sequentially performing the execution process of the program code on the basis of the execution code generated by the code extension means.

A program execution method comprising the steps of:

• reading data obtained by compressing a program code which is constituted by an execution code that is composed of process data used for an execution process and a command representing an execution process content which are arrange in order, from first storage means by a predetermined amount of data each;
• determining by type determination means as to whether or not the read data contains the command;
• storing the process data in the second storage means when it is determined that the data does not contain the command and the read data contains the process data, and generating by code extension means an execution code on the basis of the process data stored in the second storage means and the command when it is determined that the data contains the command;
• sequentially performing an execution process of the program code by execution means on the basis of the execution code generated by the code extension means.

• and
• sequentially performing an execution process of the program code on the basis of the thus generated execution code.
