Method and system for adding compressed page tables to an operating system |
摘要 |
A method for adding compressed page tables to an operating system is disclosed. An embodiment provides for a method in which a single entity, for example, an operating system has control of the compression and decompression of data and where the data is stored. When a data access is desired, the method accesses a table specifying the physical memory location of uncompressed data to determine if specified data is in uncompressed memory. The method of this embodiment accesses a table specifying the physical memory location of data in compressed memory to determine if the data is in the compressed memory. The method also access a page directory table to determine the location of the data in virtual memory in the event of a page fault. Then, this embodiment accesses the data based on the table look-up results.
