This paper proposes a method to reduce the supply voltage IR drop of 3D stacked-die systems by implementing an on-chip Buck Converter on Top die (BCT) scheme. The IR drop is caused by the parasitic resistance of Through Silicon Vias (TSV’s) used in the 3D integration. The IR drop reduction and the overhead associated with the BCT scheme are modeled and analyzed. A 3D stacked-die system is manuf...

A self adaptive particle filter method for structural system identification is presented in this paper. Such an adaptive technique that uses statistical methods to adapt the number of particles at each iteration. This method improves the efficiency of state estimation by adapting the size of sample sets during the estimation process through KLD-Sampling. Within this adaptation process the numbe...

In sub-65nm CMOS process technologies, networks-onchip (NoC) are increasingly susceptible to transient faults (i.e., soft errors). To achieve fault tolerance, Triple Modular Redundancy (TMR) and Hamming Error Correction Codes (HECC) are often employed by designers to protect buffers used in NoC components. However, these mechanisms to achieve fault resilience introduce power dissipation overhea...

Large on-chip caches account for a considerable fraction of the total energy consumption in modern microprocessors. In this context, emerging Spin-Transfer Torque RAM (STTRAM) has been regarded as a promising candidate to replace large on-chip SRAM caches in virtue of its nature of the zero leakage. However, large energy requirement of STT-RAM on write operations, resulting in a huge amount of ...

3D integrated circuits (3DICs) with through-silicon vias (TSVs) are an important direction for semiconductor-based products and “More than Moore” scaling. However, 3DICs bring simultaneous challenges of reliability (power and temperature in stacks of thinned die) as well as variability (performance and power) in advanced technology nodes. In this paper, we study variability-reliability interact...

A summary of the fifth Evaluating Collaborative Enterprises (ECE) workshop which ran on June 14th at University of Modena, Italy.

14th International Symposium of Animal Biology and Nutrition 28 -2 9 Se pt em be r 2 01 7

The 14th International HLA (human leukocyte antigen) Immunogenetics Workshop (14th-IHIWS) Biostatistics and Anthropology/Human Genetic Diversity project continues the population sampling, genotype data generation, and biostatistic analyses of the 13th International Histocompatibility Workshop Anthropology/Human Genetic Diversity Component, with the overall goal of further characterizing global ...

A change in feeding behavior on the 15th and 16th day of the maternal cycle was observed in experimental bitches whose own litter was partly replaced, on the onset of the 15th day, by foster puppies 12-13 days younger. The number of feeding acts and the overall feeding time increased, as compared with the indices for 2 days preceding the exchange of puppies (the 13th and 14th day of the materna...
