The advanced data processing on the edge devices is getting much attention in addition to the performance of cloud computing for big data analysis and artificial intelligence for the advanced cyber-physical systems and Internet of Things. This paper shows the challenges of research and development on disruptive computing which enhance the conventional computing system with high performance and low power consumption. Future R&D challenges in computing technologies involve all technology layers including algorithms, packaging, software, architecture, circuits, devices, and materials. It is important from the perspective of social implementation and efficiency to select technologies suitable for important applications from each technology layer specific to the computing domain and with consideration for the timeline, and to develop technologies through a vertical integration approach. The promoting method of implementing such R&D is also described.
