DRAM technology requires refresh operations to be performed in order to avoid data loss due to capacitance
leakage. Refresh operations consume a significant amount of dynamic energy, which increases
with the storage ...

Dependability benchmarking has become through
the years more and more important in the process of systems
evaluation. The increasing need for making systems more dependable
in presence of perturbations has contributed ...

In recent years, embedded dynamic random-access memory (eDRAM) technology has been implemented in last-level
caches due to its low leakage energy consumption and high density. However, the fact that eDRAM presents slower ...

[EN] We present a model to compute the figures of merit of self-beating Microwave Photonic systems, a novel class of systems that work on a self-homodyne fashion by sharing the same laser source for information bearing and ...
Sánchez Fandiño, Javier Antonio; Doménech Gómez, José David; Muñoz Muñoz, Pascual; Capmany Francoy, José(Optical Society of America: Open Access Journals, 2013-02-11)
[EN] We report the design, fabrication and characterization of an integrated frequency discriminator on InP technology for microwave photonic phase modulated links. The optical chip is, to the best of our knowledge, the ...
Benchmarks enable the comparison of computer-based systems attending to a variable set of criteria, such as
dependability, security, performance, cost and/or power consumption. It is not despite its difficulty, but ...
Pérez-López, Daniel; Gasulla Mestre, Ivana; Capmany Francoy, José; Sánchez Fandiño, Javier Antonio; Muñoz Muñoz, Pascual; Alavi, Hossein(Optical Society of America, 2016-09-05)
We develop, analyze and apply a linearization technique based on dual parallel Mach-Zehnder modulator to self-beating microwave photonics systems. The approach enables broadband low-distortion transmission and reception ...
