An apparatus may include a first storage location to store a key value of an activated correlated data values (CDV) pair and a second storage location to store a correlated value corresponding to the key value. An apparatus may also include a first storage location to store an instruction to activate a CDV pair and a second storage location to store an instruction to deactivate the CDV pair. A system may comprise a processor to fetch and execute a native instruction set including an instruction to activate a CDV pair and an instruction to deactivate the CDV pair, as well as a memory to store a table that includes the CDV pair. A machine-readable medium may include instructions causing a machine to perform a method comprising activating a CDV pair and performing a first task using the correlated value in parallel with a second task using the key value.
