Peer Review #2 of "Today’s computing challenges: opportunities for computer hardware design (v0.1)"

Abstract

Due to explosive increase of digital data creation, demand on advancement of computing capability is ever increasing. However, the legacy approaches that we have used for continuous improvement of three elements of computer (process, memory, and interconnect) have started facing limit, and therefore they are not as effective as they used to be and are also expected to reach the end in the near future. Evidently, it is a big challenge for computer hardware industry. However, at the same time it also provides great opportunities to hardware design industry to develop novel technologies and to take leadership away from incumbents. This paper reviews the technical challenges that today's computing systems are facing and introduces potential directions for continuous advancement of computing capability, and discusses where computer hardware designers find good opportunities to contribute.
