Abstract:

There are many interesting advances in approximate computing recently targeting the energy efficiency in system design and execution, in particular for applications of the Internet of Things and machine learning. The basic idea is to trade computation accuracy for power and energy during all phases of the computation, from data to algorithm and hardware implementation. In this talk, we will report some of our recent efforts in approximate computing for the low power design as well as security based information hiding. More specifically, we will first introduce a new data format and an estimate-and-recompute paradigm that can significantly facilitate approximate computation for energy efficient execution. Then we will demonstrate with examples the potential of embedding information in approximate hardware and approximate data, as well as during approximate computation. We will briefly discuss the security applications based on such information hiding.
