System and method for sharing a cache line between non-contiguous memory areas

A method for caching memory comprising caching two data values, each of one of two ranges of application memory addresses, each associated with one of a set of threads, by: organizing a plurality of sequences of consecutive address sub-ranges in an interleaved sequence of address sub-ranges by alter...

Zusammenfassung:A method for caching memory comprising caching two data values, each of one of two ranges of application memory addresses, each associated with one of a set of threads, by: organizing a plurality of sequences of consecutive address sub-ranges in an interleaved sequence of address sub-ranges by alternately selecting, for each thread in an identified order of threads, a next sub-range in the respective sequence of sub-ranges associated therewith; generating a mapping of the interleaved sequence of sub-ranges to a range of physical memory addresses in order of the interleaved sequence of sub-ranges; and when a thread accesses an application memory address of the respective range of application addresses associated thereof: computing a target address according to the mapping using the application address; and storing the two data values in one cache-line of a plurality of cache-lines of a cache by accessing the physical memory area using the target address.
