Hardware implementations of finite field arithmetic using normal basis are advantageous due to the fact that the squaring operation can be done at almost no cost. In this paper, a new word-parallel bit-serial finite field multiplier using normal basis is presented. The proposed architecture takes w clock cycles to compute the product bits, where the value for w, 1≤w≤ m, can be arbitrarily selec...

This paper presents a scalable architecture for the computation of modular multiplication, based on the Montgomery multiplication (MM) algorithm. A word-based version of MM is presented and used to explain the main concepts in the hardware design. The proposed multiplier is able to work with any precision of the input operands, limited only by memory or control constraints. Its architecture giv...

This paper deals with controller design issues for a neurosurgical teleoperator system. The specific application of interest consists of remotely inserting a linear-stage rigid endoscope into the patient's brain for microinvasive neurosurgery interventions. This work aims at evaluating advantages and drawbacks of using a general-purpose control architecture versus a simpler task-oriented archit...

Restricted Boltzmann Machines (RBMs) are an effective model for machine learning; however, they require a significant amount of processing time. In this study, we propose a highly parallel, highly flexible architecture that combines small and completely parallel RBMs. This proposal addresses problems associated with calculation speed and exponential increases in circuit scale. We show that this...

The expense of developing and maintaining software is the major obstacle to the routine use of parallel computation. Architecture independent programming o ers a way of avoiding the problem, but the requirements for a model of parallel computation that will permit it are demanding. The Bird-Meertens formalism is an approach to developing and executing data-parallel programs; it encourages softw...

QoS support is necessary for the Internet new applications to meet end-to-end requirements such as bandwidth, delay, jitter and packet loss. Unfortunately, DiffServ architecture can only provide limited service assurance. Thus, a trade-off between simplicity of the implementation and strength of the service guarantees has to be made. In this paper, we have focused on DiffServ architecture to im...

Foreign trade is one of the main drivers China’s spectacular rise. As it has become a determining factor in world trade, its composition, competitiveness, characteristics, and methods have important for whole world. This article provides political examination Chinese foreign architecture, considers criticisms related to it, rationale. It concludes that China – according intentions tried fit int...

This paper presents a new software architecture we have developed, known as Tinmithevo5, which is designed to streamline the process of writing applications for augmented reality and other types of virtual environments. Writing AR applications can be a complex and time consuming task, as there is little existing technology to support this process. This lack of technology requires the implementa...

We build a mathematical model to determine an optimal architecture for a multi-standard reconfigurable radio. We examine the trade-off between (a) building complex dedicated functional modules providing high performance at a high cost (as well as size and weight) (“Velcro approach”), versus (b) relying on simpler lower-level components, which reduces cost but increases system latency. On the fo...
