Attorney, Agent or Firm:
A binary program conversion apparatus capable of converting an original binary program into a new binary program which runs at higher speed in a target computer having a cache memory. The binary program conversion apparatus comprises an executing part, a generating part and a producing part. The executing part executes the original binary program. The generating part generates executed blocks information indicating first instruction blocks which are executed by the executing part. The producing part produces, based on the executed blocks information generated by the generating part, the new binary program which contains second instruction blocks corresponding to the plural of the first instruction blocks and which causes, when being executed in the computer, the computer to store second instruction blocks corresponding to the first instruction blocks executed by the executing part at different locations of the cache memory. |

DETAILED DESCRIPTION An object of the present invention is to provide a binary program conversion apparatus and a binary program conversion method which can convert an original binary program into another binary program that runs at high speed in a computer without using a source program of the original binary program.
It is another object of the present invention is to provide a program recording medium with a program for making a computer to function as such a binary program conversion apparatus.
A binary program conversion apparatus according to a first aspect of the invention is used for converting a first binary program which consists of a plural of first instruction blocks into a second binary program which is executed in a computer having a cache memory.
The binary program conversion apparatus comprises an executing part, a generating part and a producing part.
The executing part executes the first binary program.
The generating part generates executed blocks information indicating first instruction blocks which are executed by the executing part.
The producing part produces, based on the executed blocks information generated by the generating part, the second binary program which contains second instruction blocks corresponding to the plural of the first instruction blocks and which causes, when being executed in the computer, the computer to store second instruction blocks corresponding to the first instruction blocks executed by the executing part at different locations of the cache memory.
Thus, the binary program conversion apparatus of the first aspect converts a binary program (first binary program) into a new binary program (second binary program) which runs fast in the computer with the cache memory by carrying out processes involves rearranging binary codes (executed blocks).
Therefore, according to this binary program conversion apparatus, binary programs suitable for the computer having the cache memory can be obtained without using (managing) their source programs.
Actualization of the binary program conversion apparatus according to the first aspect involves the use of the producing part which produces the second binary program including a part in which the second instruction blocks corresponding to the first instruction blocks executed by the executing part arranged successively
