Abstract
Computing on time-based data is a recent evolution of research in stochastic computing. As with stochastic computing, complex functions can be computed with remarkably low area cost. Unlike stochastic computing, the latency and energy efficiency are very favorable compared to computations on conventional binary radix. In this article, the authors review and evaluate the design and implementation of arithmetic operations on time-encoded signals, with a particular focus on low power. The advantages, challenges, and potential applications are discussed.
