SYSTEM, METHOD, AND COMPUTER PROGRAM PRODUCT FOR REDUCING MEMORY WRITE OPERATIONS USING AN INSTRUCTION SET

1 . A method, comprising:

identifying write operations to be performed on a data stored in memory;

determining a difference between results of the write operations and the data stored in the memory;

storing difference information associated with the difference, using an instruction set; and

reducing the write operations, utilizing the difference information.

2 . The method of claim 1 , wherein the difference information is compressed.

3 . The method of claim 1 , wherein, in response to a read operation, the data and the difference information are retrieved, and the data is reconstructed utilizing the difference information.

4 . The method of claim 3 , wherein the difference information is retrieved from the memory.

5 . The method of claim 3 , wherein the difference information is retrieved from a buffer.

6 . The method of claim 1 , wherein the difference information is stored in a buffer.

7 . The method of claim 6 , wherein, in response to the buffer being full, the difference information is stored in the memory.

8 . The method of claim 1 , wherein the difference information is stored in a block of the memory in which corresponding data is stored.

9 . The method of claim 8 , wherein the difference information is stored in a portion of the block having a predetermined size.

10 . The method of claim 9 , wherein the predetermined size is user configured.

11 . The method of claim 9 , wherein, in response to the difference information exceeding the predetermined size, the data and the difference information are retrieved from the block, the data is reconstructed utilizing the difference information, and the reconstructed data is stored in the block.

12 . The method of claim 1 , wherein the difference is determined on a byte-by-byte basis.

13 . The method of claim 1 , wherein the difference is determined utilizing data motion estimation.

14 . The method of claim 1 , wherein the memory includes a mechanical storage device.

15 . The method of claim 14 , wherein the mechanical storage device includes a disk drive.

16 . The method of claim 1 , wherein the memory includes a non-mechanical storage device.
