Abstract
A computer system having a main memory for storing data in a compressed format and a processor cache for storing decompressed data, a method for converting the data of said main memory from compressed to uncompressed state, comprising the steps of reducing used portions of said main memory to a target value; disabling a compressor used for compressing the uncompressed data; decompressing said compressed data of said main memory; moving said decompressed data to physical addresses equal to real addresses; and releasing the memory occupied by a compressed memory director and data structures used in the above steps.
