Abstract: In one embodiment, an inter-memory transfer interface having selective data compression/decompression in accordance with the present description, selects from multiple candidate processes, a compression/decompression process to compress a region of data from a near memory before transmitting the compressed data to the far memory. In another aspect, the inter-memory transfer interface stores metadata indicating the particular compression/decompression process selected to compress that region of data. The stored metadata may then be used to identify the compression/decompression technique selected to compress a particular region of data, for purposes of locating the compressed data and subsequently decompressing data of that region when read from the far memory. Other aspects are described herein.
