Method for determining the number of processing element in moving picture estimating algorithm

摘要

PURPOSE: A method for determining processing element number in a moving pictures estimation algorithm is provided to find optimal processing element number corresponding to a size of a basic block and a searching point. CONSTITUTION: A method for determining processing element number in a moving pictures estimation algorithm includes minimal processing element number(NPE1) corresponding to a specification of a system and an application(305). A size of the minimal basic block size and the size of the minimal searching points are compared(314). The size which is determined to be smaller at the second step is determined to be a block to be divided, and the block is divided sequentially(315,316). A division processing element number(NPE2) corresponding to the number of pixels included in the block to be divided is calculated. When the NPE2 is same to the NPE1, the NPE2 is determined to be the optimal processing element number. Otherwise, an integer closest to the NPE1 is determined to be the optimal processing element number.
