Directory storage control for commonly used patterns

Abstract

A system and method are disclosed with the ability to track usage of information and determine commonly used patterns to be stored and updated in a directory. The information includes counter values that represent the frequency of occurrence of a pattern that is committed to the directory. Thus, allows the system to control and reduce the size allocated to storing information in the directory because the size is reduced by limiting address bits. This, in turn, creates additional benefits in speed and power because it allows subsystems to avoid transmitting, storing, and operating upon excessive address information.
