Smart Metering the Clouds
As cloud computing becomes increasingly pervasive, the data center energy consumption attributable to cloud computing is climbing, despite the clarion call of action to reduce consumption and reverse environmental effects. At the same time, the rising cost of energy — due to regulatory measures enforcing a “true cost” of energy coupled with finite natural resources […]
VLSI Implementation of a Low-Complexity LLL Lattice Reduction Algorithm for MIMO Detection
Lattice-reduction (LR)-aided successive interference cancellation (SIC) is able to achieve close-to optimum error-rate performance for data detection in multiple-input multiple-output (MIMO) wireless communication systems. In this work, we propose a hardware-efficient VLSI architecture of the LenstraLenstra-Lovász (LLL) LR algorithm for SIC-based data detection. For this purpose, we introduce various algorithmic modifications that enable an efficient […]
VLSI Macromodeling and Signal Integrity Analysis via Digital Signal Processing Techniques
Linear macromodeling has been applied to highfrequency circuit simulations to accelerate the global interconnect system simulation process. By approximating tabulated structure response data, reduced macromodels can be generated. However, conventional macromodeling approaches suffer from numerical robustness and convergence problems. This paper aims to apply digital signal processing techniques to facilitate the macromodeling process. Besides improving […]
