Abstract
When an information processing apparatus is requested to transfer to a system interruption state, the information processing apparatus determines whether to compress data at each page, and generates a hibernation image configured of compressed data and non-compressed data. In an operating system activation period, the information processing apparatus determines whether to execute hibernation activation processing before initializing a memory management mechanism. In a case where the information processing apparatus executes the hibernation activation processing, the information processing apparatus reduces a size of the memory management region up to the size required for the initialization of the kernel, and reads the compressed data in parallel with initialization of hardware. After initializing the kernel, the information processing apparatus reads the non-compressed data in parallel with decompression of the compressed data.
