SYSTEMS, METHODS AND DEVICES FOR ELIMINATING DUPLICATES AND VALUE REDUNDANCY IN COMPUTER MEMORIES

A computer memory compression method involves analyzing (1210) computer memory content with respect to occurrence of duplicate memory objects as well as value redundancy of data values in unique memory objects. The computer memory content is encoded (1220) by eliminating the duplicate memory objects and compressing each remaining unique memory object by exploiting data value locality of the data values thereof. Metadata (500) is provided (1230) to represent the memory objects of the encoded computer memory content. The metadata reflects eliminated duplicate memory objects, remaining unique memory objects as well as a type of compression used for compressing each remaining unique memory object. A memory object in the encoded computer memory content is located (1240) using the metadata (500). 计算机存储器压缩方法涉及关于副本存储器对象的出现以及独特存储器对象中数据值的值冗余来分析(1210)计算机存储器内容。通过消除副本存储器对象和经由利用每个其余独特存储器对象的数据值的数据值局部性对每个其余独特存储器对象压缩，来对计算机存储器内容进行编码(1220)。提供(1230)代表所编码的计算机存储器内容的存储器对象的元数据(500)。元数据反映了被消除的副本存储器对象、其余独特存储器对象以及用于压缩每个其余独特存储器对象的压缩类型。使
