Abstract
According to at least one example embodiment, a method and corresponding apparatus for conditionally storing data include initiating an atomic sequence by executing, by a core processor, an instruction/operation designed to initiate an atomic sequence. Executing the instruction designed to initiate the atomic sequence includes loading content associated with a memory location into a first cache memory, and maintaining an indication of the memory location and a copy of the corresponding content loaded. A conditional storing operation is then performed, the conditional storing operation includes a compare-and-swap operation, executed by a controller associated with a second cache memory, based on the maintained copy of the content and the indication of the memory location.
