Abstract: As there are several factors that affecting the performances of the embedded systems，the article particularly analyzes the factors that affect the performances of the embedded systems，and proposes a point that hardware/software partitioning based on multi-target.Bring IP and software framework reuse into hardware/software partitioning method.Mapping the complex embedded system configuration into DAG（Direct Acyclic Graph）.Firstly proposes the concept of performance priority，and speeds up the calculating of the algorithm through the import of operation research and data preprocess.

Key words: multi-target evaluation, SoC design, hardware/software partitioning, algorithm optimization, IP core reuse, capability priority
