A fast searching algorithm for Integrated Circuit (IC) frames is put forward and a corresponding hardware system for the recognition of real time IC images is researched.

In this paper,a new fast searching algorithm is proposed on the basis of comprehensive analysis of variety of searching motion estimation algorithm and it′s basic principles.

In order to reduce the motion estimation time,this paper proposes a new fast search algorithm in detail,and compares it with some previous fast search algorithms.

In order to reduce the time and search frequency,fast search algorithm is often adopted.

Aimed at solving the problem which consisting in conventional mean pyramid structure search algorithm that we are not sure from which point to start and we don t have restrictions to narrow the search range,this paper presents an improved fast search algorithm,which can start the search from the point that near the closest codeword and narrow the search range.

A real-valued objective function is constructed with respect to the string predicate which does not meet a given path condition,and its minimum is computed by using a speedy descent search algorithm.
