http://www.peertopatent.org/patent/26/prior_art/list Methods and apparatus to identify memory communications are described. In one embodiment, an access to a stack pointer is monitored, e.g., to maintain a stack tracker structure. The information stored in the stack tracker structure may be utilized to generate a distance value corresponding to a relative distance between a load instruction and a previous store instruction. en-us Stack tracker Patent/Application #: Patent number: 7017026<br/>Description: Apparatus and methods to track a register address values with a stack pointer tracker.
