Abstract

A method and system for memory management is disclosed. The disclosed method and system can prevent performance degradation due to automatic garbage collection associated with memory allocation for image processing. An image processing program includes two program modules. The first program modules is composed with a first language supporting a garbage collection feature but does not have a direct memory access which may trigger the garbage collection feature. The second program module is composed with a second language lacking the garbage collection feature. The image processing program delegates memory allocation for image processing to the second program module to prevent unnecessary activation of the garbage collection feature.

Claims

1. A method of processing image data, the method comprising:

providing computer-executable software comprising a first module and a second module, the first module corresponding to codes written in a JAVA programming language, the second module corresponding to codes written in a non-JAVA programming language;

wherein the JAVA programming language requires automatic memory garbage collection when performing a memory allocation routine of the JAVA programming language whereas the non-JAVA programming language does not require automatic memory garbage collection when performing a memory allocation routine of the non-JAVA programming language;

wherein the second module comprises a memory allocation routine that does not accompany memory garbage collection;

wherein the first module comprises an image processing routine of the JAVA programming language for processing image data in a memory allocated by the memory allocation routine of the second module;

wherein the first module does not comprise the memory allocation routine of the JAVA programming language and is configured to activate the memory allocation routine of the second module for performing memory allocation without automatic memory garbage collection; and

executing computer-executable software in a computing system such that the first module and the second module are executed without automatic memory garbage collection when performing the memory allocation routine of the second module.

2. The method according to claim 1,

wherein the second module is configured to, when executed, return reference data identifying an allocated memory;

wherein the first module is configured to, when executed, cause the computing system to write image data in the allocated memory using the reference data.

3. The method according to claim 2, wherein the second module is further configured to return the reference data in an integer type.

4. The method according to claim 3,

wherein the first module is further configured to request the second module to write the image data in the allocated memory by transferring the reference data to the second module, and

wherein the second module is further configured to transform the reference data into a pointer type and to write the image data in the allocated memory using the reference data into the pointer type.

5. The method according to claim 1, wherein the codes of the first module uses a Java Native Interface (JNI) for activating the memory allocation routine of the second module.

6. A non-transitory computer readable recording medium in which a program enabling the method as claimed in claim 1 to be carried out is recorded.

7. A system comprising:

a processor; and

a memory storing a computer program that the processor executes,

wherein the computer program enables the system to carry out the method as claimed in claim 1 when the computer program is executed by the processor.

8. A computer program stored in a non-transitory recording medium comprising:

a first code part written in a JAVA programming language and corresponding to a first module of computer-executable software; and

a second code part written in a non-JAVA programming language and corresponding to a second module of computer-executable software,

wherein the JAVA programming language requires automatic memory garbage collection when performing a memory allocation routine of the JAVA programming language whereas the non-JAVA programming language does not require automatic memory garbage collection when performing a memory allocation routine of the non-JAVA programming language,

wherein the second module comprises a memory allocation routine that does not accompany memory garbage collection,

wherein the first module comprises an image processing routine of the JAVA programming language for processing image data in a memory allocated by the memory allocation routine of the second module,

wherein the first module does not comprise the memory allocation routine of the JAVA programming language and is configured to activate the memory allocation routine of the second module for performing memory allocation without automatic memory garbage collection such that the first module and the second module are executed without automatic memory garbage collection when performing the memory allocation routine of the second module.

9. The computer program according to claim 8, wherein the second code part comprises at least one command for returning reference data identifying an allocated memory,

wherein the first code part further comprises codes to write image data in the allocated memory using the reference data.
