This paper describes a hardware accelerator for elliptic curve cryptography. The accelerator performs Galois field operations as a series of microcode instructions operating on 32-bit subsections of operands, which represent elements from GF(2) in a binary polynomial basis. The accelerator may be used for arbitrary size elliptic curves up to a field degree of 512. Parallelism between operations...

Being an integral part of accelerator software, accelerator description aims to provide an external representation of an accelerator’s internal model and associative effects. As a result, the choice of description formats is driven by the scope of accelerator applications and is usually implemented as a tradeoff between various requirements: completeness and extensibility, user and developer or...

This paper presents an accelerator for k-th nearest neighbor thinning, a run time intensive algorithmic kernel used in recent multi-objective optimizers. We discuss the thinning algorithm and the accelerator architecture with its modules and operation, and evaluate the accelerator with respect to two different application scenarios. The first is an embedded computing scenario where the accelera...

The Unified Accelerator Libraries[1] are designed as a customizable and extendible environment for developing diverse accelerator applications. Its main architectural principle is a separation of physical entities and mathematical abstractions from algorithms. The accelerator algorithms are implemented as classes that share data via Common Accelerator Objects (Element, Bunch, Twiss, etc.). This...

this paper presents the results of a series of monotonic and post-cyclic triaxial tests carried out on a clay specimen and three types of clay-sand mixed specimens. the focus of the paper is on the post-cyclic mechanical behavior of the mixed specimens, as compared to their monotonic behavior. analyses of the tests results show that cyclic loading degrade undrained shear strength and deformatio...

mixed clayey soils occur as mixtures of sand (or gravel) and clay in widely varying proportions. their engineering behavior has not been comprehensively studied yet. an experimental program, comprising monotonic, cyclic, and post-cyclic triaxial tests was undertaken on compacted clay-granular material mixtures, having different proportions of clay and sand or gravel. this paper presents the res...

An overview of the framework of Unified Accelerator Libraries (UAL) is presented. The UAL framework is a necessary and logical step in the UAL evolution. It intends to offer a standard-based infrastructure that facilitates compatible and independent implementation of accelerator applications and the development of interoperable Accelerator Simulation Facilities. The paper explain the two major ...

We present a flexible accelerator designed for networking applications. The accelerator can be utilized efficiently by a variety of Network Processor designs. Many Network Processors employ hardware accelerators for implementing key domain-specific tasks. New applications require new tasks, such as pattern matching, to be performed on network packets in real-time. Using our proposed accelerator...
