Abstract

See full text

A method to merge one or more non-transactional stores and one or more thread-specific transactional stores into one or more cache line templates in a store buffer in a store cache. The method receives a thread-specific non-transactional store address and a first data, maps the store address to a first cache line template, and merges the first data into the first cache line template, according to a store policy. The method further receives a thread-specific transactional store address and a second data, maps the thread-specific store address into a second cache line template, according to a store policy. The method further writes back a copy of a cache line template to a cache and invalidates a third cache line template, which frees the third cache line template from a store address mapping.
