Abstract: Based on the recent trend of SoC development and the effect of parallel partitioning, a method of SoC parallel design at the system-level is presented. Parallelism of SoC model is analyzed. A new algorithm is proposed to partition the SoC model. The algorithm is based on the greedy rule, which deals with the load balancing problem. Experimental results show that partitioning at the system level of SoC is desirable for improving time consumption and overcoming the low-efficiency problems in SoC system.

Key words: SoC, system-level design, parallel partitioning, load balancing
