Abstract
A method for storing lines of data in a data array of a cache memory mapped to a main memory of a processing system. The data array includes data storage lines having equal lengths. The method includes compressing at least one of the lines of data, fitting the compressed line of data within a subsection of one of the data storage lines, and pointing to the subsection using a tag array. When lines of data are stored in compressed form, more lines can fit into the cache, and a probability of a cache hit is increased.
