Abstract
Methods and apparatus for reducing the search space processed by mask matching methods. The search space is reduced by grouping the candidate bit patterns into groups and subgroups that have internal bit agreement between the members. By only applying the mask matching methods to a select number of groups selected by their bit agreement with the target bit pattern, the computation time and memory requirement of the mask matching method is reduced.
