(English Abstract)
Flash memory becomes popular storage for small devices due to its efficiency, portability, low power consumption and large capacity. Unlike on hard disks, however, write operation on flash memory is much more expensive than read operation, so that it is critical for performance enhancement to reduce the number of executions of write operation. This paper proposes static analysis to rewrite a program to reduce the total number of write operations by merging writable data in a minimum number of pages. To achieve this, we collect information about writable areas by static analysis, and about frequently executed paths by profiling for practicality, and combine both to rewrite the application program to reallocate data. The performance enhancement gained from the proposed methods is shown using a FAST simulator.
