Network-on-Chip (NoC) is a promising interconnection solution for system-on-chip because of its high scalability. Mapping the IP cores onto the nodes of NoC is an important phase of NoC design. Mapping results can greatly affects the performance and energy consumption of the chip. This paper introduces the state-of-the-art of NoC mapping algorithms in detail, categorize them into three classes, and carefully analyzes their advantages and disadvantages. Finally, describes a GA-based NoC mapping algorithm using ordinal representation. Experiments show that algorithm is efficiency and accuracy.
