Trends of terascale computing Chips in the next ten years

摘要

Moore's law steadily continues though facing a number of challenges. This paper identifies ongoing and desirable trends to exploit the technology capacity and further Moore's law for terascale on-chip computing architectures in the next ten years. Four foreseeable trends are: from single core to many cores, from bus-based to network-based interconnect, from centralized memory to distributed memory, and from 2D integration to 3D integration. We motivate these trends and show that the number of design choices for computing chips is increasing rapidly, leading to an exploding design space with uncountable opportunities for the innovative architect. Moreover, we envision that the multi-core Network-on-Chip will become an infrastructure backbone and accumulate many other infrastructural functions such as memory, power and resource management, testing and diagnostic services.
