SoC has driven the evolution of embedded systems or consumer electronics. Multi-core/multi-IP is the key technology to integrate many functions on a SoC for future embedded applications. In this paper, the transition of SoC and its required functions for cellular phones as an example is described. And the state-of-the-art multi-core technology of homogeneous type and heterogeneous type are shown. When many cores and IPs are integrated on a chip, collaboration between cores and IPs becomes important to meet requirement. To realize it, “MPSoC Platform” concept and elementary technology for this platform is described.
