Multithreaded Peripheral Processor for a Multicore Embedded System
2012
Multithreaded and multicore architectures represent a good solution used for increasing of parallelism degree exploited in modern computing systems and they can reduce the power dissipated in the chip by using low-frequency clock signals. These advantages recommend these parallel architectures for integration in the embedded systems, with restrictions imposed by the relatively small integration area. Particularities of embedded applications require hardware support able to handling in real time the peripheral interrupt requests. The performance of this hardware influences the performance of the entire parallel system. The current trend is to integrate in one microcontroller more processors …
Concept and Development of Modular VLIW Processor Based on FPGA
2010
Modern FPGA chips, with their larger memory capacity and reconfigurability potential, are opening new frontiers in rapid prototyping of embedded systems. With the advent of high density FPGAs it is now possible to implement a high performance VLIW processor core in an FPGA. Architecture based on Very Long Instruction Word (VLIW) processors are an optimal choice in the attempt to obtain high performance level in embedded system. In VLIW architecture, the effectiveness of these processors depends on the ability of compilers to provide sufficient instruction level parallelism(ILP) in program code. Using advanced compiler technology could take these functions, This paper describes research resu…
Flexible VLIW processor based on FPGA for real-time image processing
2011
Modern FPGA chips, with their larger memory capacity and reconfigurability potential, are opening new frontiers in rapid prototyping of embedded systems. With the advent of high density FPGAs it is now possible to implement a high performance Very Long Instruction Word (VLIW) processor core in an FPGA. With VLIW architecture, the processor effectiveness depends on the ability of compilers to provide sufficient Instruction Level Parallelism (ILP) from program code. This paper describes research result about enabling the VLIW processor model for real-time processing applications by exploiting FPGA technology. Our goals are to keep the flexibility of processors in order to shorten the developm…
Elementary transformation analysis for Array-OL
2009
Array-OL is a high-level specification language dedicated to the definition of multidimentional intensive signal processing applications. It allows to specify both the task parallelism and the data parallelism of these applications on focusing on their complex multidimensional data access patterns. Several tools exist for implementing an Array-OL specification as a data parallel program. While Array-OL can be used directly, it is often convenient to be able to deduce part of the specification from a sequential version of the application. This paper proposes such an analysis and examines its feasibility and its limits.
Combining Mendonça-Cipolla self-calibration and scene constraints
2011
International audience; In this paper, we propose a method that combines plane parallelism and the Mendonça/Cipolla self-calibration constraints. In our method each pair of images is treated independently and can therefore use a different pair of parallel planes not necessarily visible in the other views. While, for each pair of images, constraints on the singular values of the essential matrix provide two algebraic constraints on the intrinsic parameters, those we derive from plane parallelism have the advantage of providing two additional ones making the calibration of a no-skew camera possible from two images only.
La influencia de Pierre Bayle en la construcción de la segunda antinomia de la razón pura
2020
This paper aims to establish precisely the scope of Pierre Bayle’s influence on the construction of Kant’s second antinomy of pure reason, since there is a remarkable parallelism between this second cosmological conflict and the argument against extension of the article “Zeno of Elea” of Bayle’s Dictionary. It is argued that Bayle, employing the skeptical method in metaphysical research, has a major influence on the construction of the main arguments of the second antinomy and sets a precedent for its logical solution.
THE HOUSE THAT IS NOT THERE: THE HOME FEELING IN JONATHAN RABAN’S LANGUAGE IN FOREIGN LAND
2021
This work aims to analyse the novel of the journalist and novelist Jonathan Raban, Foreign Land, trying to highlight how, through the language used, the author manages to elaborate a personal, intimate and even dramatic vision of themes such as the relationship between man and the environment, the sense of uprooting and the love for the sea that are typical themes of travel literature within which this novel is enrolled. More specifically, the text, taken from a work of reading analysis and translation of the Rabanian work from English to Italian, aims to highlight the metaphorical dimension of the home feeling made particularly effective by the parallelism between the inner dimension of th…
And Now for Something Completely Different: Running Lisp on GPUs
2018
The internal parallelism of compute resources increases permanently, and graphics processing units (GPUs) and other accelerators have been gaining importance in many domains. Researchers from life science, bioinformatics or artificial intelligence, for example, use GPUs to accelerate their computations. However, languages typically used in some of these disciplines often do not benefit from the technical developments because they cannot be executed natively on GPUs. Instead existing programs must be rewritten in other, less dynamic programming languages. On the other hand, the gap in programming features between accelerators and common CPUs shrinks permanently. Since accelerators are becomi…
Quantum Security Proofs Using Semi-classical Oracles
2019
We present an improved version of the one-way to hiding (O2H) Theorem by Unruh, J ACM 2015. Our new O2H Theorem gives higher flexibility (arbitrary joint distributions of oracles and inputs, multiple reprogrammed points) as well as tighter bounds (removing square-root factors, taking parallelism into account). The improved O2H Theorem makes use of a new variant of quantum oracles, semi-classical oracles, where queries are partially measured. The new O2H Theorem allows us to get better security bounds in several public-key encryption schemes.
The Peter Pan syndrome: Was James M. Barrie anorexic?
1989
Recently, anorexia nervosa has been referred to as the “Peter Pan syndrome,” a metaphor based on the theme of not growing up. Beside the fact that Peter Pan was a “boy who would not grow up,” another parallelism with anorexia nervosa may lie within the creator himself. We discuss the possibility that James M. Barrie, author of “Peter Pan,” might have been himself anorexic in childhood and adolescence.
