Abstract
A method and apparatus for controlling data organization in a tiered memory system, where the system comprises a lower and higher bandwidth memories. Accesses to the tiered memory system by an action of a computing device in a first time interval are monitored to determine a first measure of bandwidth utilization, from which it is determined if the action is in a high bandwidth phase for which a first measure of bandwidth utilization is greater than an upper value. It is further determined, from confidence counters, if a monitored access is consistent with respect to the first instructions or with respect to a memory address of the access. Data associated with the access is moved from the lower bandwidth memory to the higher bandwidth memory when the action is in a high bandwidth phase, the access is consistent, and bandwidth utilization of the higher bandwidth memory is below a threshold.
