The aim of the regional research project SIMPAA2, which continues the former national research SIMPAA project, is the realization of a hardware simulator of MIMO propagation channels for UMTS and WLAN applications. The simulator must reproduce the behavior of the radio propagation channel, thus making it possible to test "on table" the mobile radio(More)
This paper proposes a new approach dealing with the tedious problem of NoC guaranteed traffics according to GALS constraints impelled by the upcoming large System-on-Chips with multiclock domains. Our solution has been designed to adjust a trade-off between synchronous and clockless asynchronous techniques. By means of smart interfaces between synchronous(More)
– This paper presents the realization of the digital block of a hardware simulator of MIMO propagation channels for UMTS and WLAN applications. The hardware simulator must reproduce the behavior of the radio propagation channel, thus making it possible to test " on table " the mobile radio equipments. The advantages are: low cost, short test duration,(More)
Faces play an important role in guiding visual attention, and thus, the inclusion of face detection into a classical visual attention model can improve eye movement predictions. In this study, we proposed a visual saliency model to predict eye movements during free viewing of videos. The model is inspired by the biology of the visual system and breaks down(More)
In this paper, we describe the architecture and implementation of 3D multiprocessor with 3D NoC. The 2 tiers design is based on 16 processors communicating using a 4x2 mesh NoC and will be fabricated using Tezzaron technology with 130 nm Global Foundaries low power standard library. Due to the limitation when investigating NoC performance using simulation,(More)
—Back-Projection (BP) is a costly computational step in tomography image reconstruction such as Positron Emission Tomography (PET). To reduce the computation time, this paper presents a Pipelined, Pre-fetch and Par-allelized Architecture for PET BP (3PA-PET). The key feature of this architecture is its original memory access strategy, masking the high(More)
The human vision has been studied deeply in the past years, and several different models have been proposed to simulate it on computer. Some of these models concerns visual saliency which is potentially very interesting in a lot of applications like robotics, image analysis , compression, video indexing. Unfortunately they are compute intensive with tight(More)
Graphical Processing Units (GPU) architectures are massively used for resource-intensive computation. Initially dedicated to imaging, vision and graphics, these architectures serve nowadays a wide range of multi-purpose applications. The GPU structure, however, does not suit all applications. This can lead to performance shortage. Among several(More)
The ever increasing density of integration makes the NoC a relevant communication design paradigm even for FPGAs. But NoC are always designed without considerations of applications and programming models, like busses and crossbars. Dealing with parallelism is still challenging. One way is to take into account the parallel programming model and application(More)
