This is a distinguished talk as part of the NUS Computer Science Research Week 2019 (http://researchweek.comp.nus.edu.sg).

Abstract:

Communication between IC components in an electronic device is one of the key components determining the performance of the device. The increase in the volume of digital data calls for ever higher throughputs between chips. The standard response has been to increase the communication rate. This leads to increased susceptibility to noise, and to an unproportionally higher power consumption. The use of higher speeds is at the core of this problem, and the apparent need to do so is the inefficient use of the available bandwidth. In this talk I will introduce Chord Signaling, an information theoretic class of signaling methods for chip-to-chip communication that makes a more efficient use of the bandwidth. I will explain parts of the theory, and how it can be used in new SerDes architectures for very high speed and low power links of various complexities.

The talk starts with a tutorial on the preliminaries and the theoretical foundations of this topic.
