Through Silicon Via (TSV) can be used to increase interconnect bandwidth, reduce wire delay due to shorter vertical signal path, and improve power efficiency [1–3]. Via Reveal-a kind of wafer back side process moduleplays an important role in the successful implementation of TSV. In via-first and via-mid TSV integration flows, Si must be removed from the backside of the wafer to make contact with...
To meet performance goals at the lowest possible cost, reconfigurable SIMD/MIMD architectures have emerged to exploit application parallelism. In this paper, we investigate the energy and flexibility tradeoffs of such architectures by designing our own reconfigurable SIMD/MIMD system, ParaFlex, using simple in-order processor components and evaluating the associated design decisions. We observe that,...
Traditional workflow management technology can deal with pre-defined business processes well. However, a practical ad-hoc process case in knowledge-intensive domain is often driven by not only process control, but also the real-time application data or user interactions. So the structure of those processes are hard to be completely fixed ahead. In addition, as the only basic element in traditional...
This paper will provide a frequency domain design method for PID controllers, which is based on a least-squares fit of the actual to the desired open-loop Nyquist plot. The algorithm is simple and achieves a unique minimum of the sum of the squared errors for a given desired response. Graphical measures will be introduced which will aid the designer in assessing whether the desired performance is...
Dynamic matrix controllers (DMC) and model predictive controllers (MPC) have found wide application in the process industries. In order to design such a controller, a step response model of the process is often used. This paper will provide an algorithm for obtaining the step response model of a process based on closed-loop operating data generated by a step change in the setpoint. This algorithm...
This paper describes a novel control system design methodology in which a process frequency response estimate, along with an associated modelling error, are used to design a robust parametric controller based on a user-specified, closed-loop transfer function. The controller parameters are obtained from an iterative procedure which minimizes the sum of squared differences between the estimated and...
