Survey on chiplets: interface, interconnect and integration methodology

Abstract

With the end of Moore's Law and Dennard scaling, it has become increasingly difficult to implement high-performance computing systems on a monolithic chip. The chiplet technology that integrates multiple small chips into a large-scale computing system through heterogeneous integration is one of the important development directions of high-performance computing. Chiplet-based systems have huge advantages over monolithic chip in terms of design and manufacturing cost and development efficiency. In this survey, we summarized the concept and history of chiplet and introduce the critical technology needed to implement chiplet-based system. Finally, we discuss several future research directions of chiplet-based system.
