The ever increasing demand in enhancing the ability of processors to handle the complex and challenging processes has resulted in the integration of a number of processor cores into one chip. Still the load on the processor is not less in generic system. This load is reduced by supplementing the main processor with Co-Processors, which are designed to work upon specific type of functions like n...

Elliptic curve cryptography plays a crucial role in networking and communication security. ECC have evolved in the recent past as an important alternative to established systems like RSA. This paper describes the implementation of an elliptic curve coprocessor based on the FPGA , which can provide a significant speedup for these cryptosystems. The FPGA configuration file is synthesized from VHD...

In the explosive growth of wireless and networking applications, Digital Signal Processing (DSP) operations are extensively used for characterizing and controlling the discrete input signals. For those DSP operations, Finite Impulse Response (FIR) filter is used to filter the unwanted/noise/distorted signals from the discrete input signals. In this study, design of Pipelined Distributed Arithme...

The relationship between the elementary operations underlying the processing of numerical information and performance on psychometrically derived ability measures defining the Numerical Facility, Perceptual Speed, General Reasoning, and Memory Span factors was examined for a sample of 112 Air Force recruits. The process variables were derived based on a componential model for arithmetic and an ...

An Arithmetic logic Unit (ALU) is an integral part of a computer processor. It has the capability of performing a no. of different arithmetic and logic operations such as addition, subtraction, bit-shifts and magnitude comparison. ALUs of various bit-widths are frequently required in very large-scale integrated circuits (VLSI) from processors to application specific integrated circuits (ASICs)....

The recent discovery of the memristor has renewed the interest for fast arithmetic operations via high-radix numeric systems. In this direction, a conceptual solution for high-radix memristive arithmetic logic units (ALUs) was recently published. The latter combines CMOS circuitry for data processing and a reconfigurable “segmented” crossbar memory block. In this paper we build upon such a conc...

The COordinate Rotation DIgital Computer (CORDIC) algorithm is an arithmetic algorithm to evaluate various elementary functions through a series of iterative operations. In this paper, a high-speed sine/cosine generator is based on double rotation of the original CORDIC algorithm by predicting all the rotation directions from the initial input angle. The proposed architecture has a simple predi...
