Mapping Performance Data to Memory Objects

Memory objects are components in the memory subsystem, such as cache-lines, pages, and memory-banks. The object is determined from an index computed from the virtual and/or physical address as recorded. Memory objects are predefined for virtual pages and physical pages, for sizes of 8 KB, 64 KB, 512 KB, and 4 MB. You can define others with the mobj_define command in the er_print utility. You can also define custom memory objects using the Add Memory Objects dialog box in the Analyzer, which you can open by clicking the Add Custom Memory Object button in the Set Data Presentation dialog box.
