Low-power design has gained much attention recently, especially for computing on batterypowered equipments. Reducing BTB (branch target buffer) accesses is an effective way to reduce processor power consumption, since BTB consumes a significant portion of power in a processor. In this paper, we propose two approaches to reduce BTB accesses. The first approach expects the distance of every two d...

Métodos e técnicas para compressão de dados têm sido utilizados para o reconhecimento de padrões, incluindo a classificação automática de textos. A eficiência do método Prediction by Partial Matching (PPM) como classificador textual já foi comprovada em diversos trabalhos, entre eles a atribuição de autoria para textos em português. As classes utilizadas no processo de classificação não precisa...

The growing demand for wind power has resulted in a market that naturally favors development of new wind farms over improvement of their performance. A chain of opportunities for performance improvement of any wind energy project parallels the supply chain activities. Raising energy and transportation costs are a complicating factor of the performance improvement projects. One of the weakest po...

Model predictive control (MPC) based methods are gaining more and more attention in power converters and electrical drives. Nevertheless, high computational burden of MPC is an obstacle for its application, especially when the prediction horizon increases extends. At the same time, increasing the prediction horizon leads to a superior response. In this paper, a long horizon MPC is proposed to c...

In this paper, a link gain prediction-based power control scheme is designed for DS-CDMA cellular mobile systems. The link gain prediction can help to remove the interference of the power control adjustment itself. The pipeline recurrent neural network (PRNN) with extended recursive least square (ERLS) is adopted for the prediction. This PRNN/ERLS predictor possesses infinite memory of past sig...

Prediction of the rapidly fading envelope of a mobile radio channel enables a number of capacity improving techniques like fast resource allocation or fast adaptive modulation. Some power prediction algorithms are based on linear prediction of the taps of the complex impulse response and then forming the power prediction as the sum of the absolute square of the prediction of the taps in the imp...
