Online Mode Switch Algorithms for Maintaining Data Freshness in Dynamic Cyber Physical Systems Abstract Maintaining the freshness of real-time data is one of the crucial design issues in cyber-physicalsystems (CPS). Past studies have focused on designing update algorithms to minimize the workload imposed by a fixed set of update tasks while ensuring the temporal validity of data. In this paper, we revisit this problem in dynamic cyber-physical systems (DCPS) […]

Comments Off on Multiplier less Unity-Gain SDF FFTs
Posted in: IEEE 2017, VLSI
Multiplier less Unity-Gain SDF FFTs Abstract: In this brief, we propose a novel approach to implement multiplierless unity-gain single-delay feedback fast Fourier transforms (FFTs). Previous methods achieve unity-gain FFTs by using either complex multipliers or nonunity-gain rotators with additional scaling compensation. Conversely, this brief proposes unity-gain FFTs without compensation circuits, even when using nonunity-gain rotators. […]
