Explores the unique hardware programmability of FPGA-based embedded systems, using a learn-by-doing approach to introduce the concepts and techniques for embedded SoPC design with Verilog An SoPC (system on a programmable chip) integrates a processor, memory modules, I/O peripherals, and custom hardware accelerators into a single FPGA (field-programmable gate array) device. In addition to the customized software, customized hardware can be developed and incorporated into the embedded system as well—allowing us to configure the soft-core processor, create tailored I/O interfaces, and develop specialized hardware accelerators for computation-intensive tasks. Utilizing an Altera FPGA prototyping board and its Nios II soft-core processor, Embedded SoPC Design with Nios II Processor and Verilog Examples takes a «learn by doing» approach to illustrate the hardware and software design and development process by including realistic projects that can be implemented and tested on the board. Emphasizing hardware design and integration throughout, the book is divided into four major parts: Part I covers HDL and synthesis of custom hardware Part II introduces the Nios II processor and provides an overview of embedded software development Part III demonstrates the design and development of hardware and software of several complex I/O peripherals, including a PS2 keyboard and mouse, a graphic video controller, an audio codec, and an SD (secure digital) card Part IV provides several case studies of the integration of hardware accelerators, including a custom GCD (greatest common divisor) circuit, a Mandelbrot set fractal circuit, and an audio synthesizer based on DDFS (direct digital frequency synthesis) methodology While designing and developing an embedded SoPC can be rewarding, the learning can be a long and winding journey. This book shows the trail ahead and guides readers through the initial steps to exploit the full potential of this emerging methodology.
This book emphasized on FPGA design to develop AES CORE using verilog HDL. Mainly the work focus on 5 modules like, key generation, shift rows, mix columns, xoring module and top module- integration. All these modules are authorized in verilog HDL language. The key generation module generates required keys from the given key. The left circular shift operation is performed by shift rows. The mix columns perform the matrix multiplication with constant matrix. Xoring module specifies the xoring the text data with the key. The top module indicates the integration of all modules and it is treated as the AES Core. Prior to AES, Data Encryption Standard (DES) is a widely used method of data encryption using a private (secret) key that was so difficult to break. With the Triple DES implementation of DES, there are 5.1 * 10^33 or more possible encryption keys that can be used.
This book gives the complete information on VHDL & Verilog coding logic for a few analog and digital circuits with their test bench for verification. Hardware Description Language (HDL) is a Computer Aided Design (CAD) tool for the modern design synthesis of digital systems. The recent steady advances in semiconductor technology continue to increase the power and complexity of digital systems. Due to their complexity, such systems cannot be realized using discrete Integrated Circuits (ICs). They are usually realized using high-density programmable chips, such as Application Specified Integrated Circuits (ASICs) and Field Programmable Gate Arrays (FPGAs) and require sophisticated CAD tools. HDL is an integral part of such tools. HDL offers the author a very efficient tool for implementing and synthesizing design on chips. The author uses HDL to describe the system in a computer language that is similar to several commonly used software languages such as C Debugging. The design is easy, since HDL packages implement simulators and test benches. The two widely used Hardware Description Languages are Very-high-speed integrated circuits Hardware Description Language (VHDL) and Verilog.
This book proposes design and architecture of a dynamically scalable dual-core pipelined processor. Methodology of the design is the core fusion of two processors where two independent cores can dynamically morph into a larger processing unit, or they can be used as distinct processing elements to achieve high sequential performance and high parallel performance. Processor provides two execution modes. Mode1 is multiprogramming mode for execution of streams of instruction of lower data width, i.e., each core can perform 16-bit operations individually. Performance is improved in this mode due to the parallel execution of instructions in both the cores at the cost of area. In mode2, both the processing cores are coupled and behave like single, high data width processing unit, i.e., can perform 32-bit operation. Additional core-to-core communication is needed to realise this mode. The mode can switch dynamically; therefore, this processor can provide multifunction with single design. Design and verification of processor has been done successfully using Verilog on Xilinx 14.1 platform. The processor is verified in both simulation and synthesis with the help of test programs.

The discovery of interesting patterns from database transactions is one of the major problems in knowledge discovery in database. One such interesting pattern is the association rules extracted from these transactions. The goal of this research was to develop and implement a parallel algorithm for mining association rules. We implemented a parallel algorithm that used a lattice approach for mining association rules. The Dynamic Distributed Rule Mining (DDRM) is a lattice-based algorithm that partitions the lattice into sublattices to be assigned to processors for processing and identification of frequent itemsets. We implemented the DDRM using a dynamic load balancing approach to assign classes to processors for analysis of these classes in order to determine if there are any rules present in them. Experimental results show that DDRM utilizes the processors efficiently and performed better than the prefix-based and Partition algorithms that use a static approach to assign classes to the processors. The DDRM algorithm scales well and shows good speedup.
Video multicasting over Wireless Ad hoc Networks (WAHNs) is bandwidth-efficient compared to multiple unicast sessions. However, video multicasting poses great challenges over WAHNs. One main challenge of video multicasting in WAHNs for heterogeneous destinations is the assignment of Video Descriptions (VDs) and the construction of multicast tree. However, the assignment of VDs and the construction of multicast tree can greatly affect user satisfaction (i.e., affect the quality of the received video). In this book, we introduce novel approaches to improve the user satisfaction for a set of heterogeneous multicast destinations. The main idea of our approaches is to employ the independent-description property of Multiple Description Coding (MDC) along with multiple multicast trees. However, many questions are raised: How multiple multicast trees should be constructed? How VDs should be assigned? Is it better to construct multiple multicast trees first and then assign the VDs? Or is it better to assign the VDs first and we then construct multiple multicast trees? Should we perform that in a distributed manner or in a centralized manner?
In this study we have tried to harvest labeled clusters of semantically similar named entities which can be used as a first step for web document clustering. We first collect ~44,000 named entities from a thesaurus which is constructed by Dekang Lin applying a word similarity measure based on their distributional pattern. Using their similarity metrics and CLUTO clustering software, we create 2000 semantically similar clusters of the named entities. Then we collect ~305,500 label-instance pairs from the 2007 English Wikipedia dump and implement a labeling algorithm presented by Benjamin Van Durme and M.Pasca (2008) to assign a label to the clusters. This automatic lableing task is able to assign a label which describes the majority of the named entities in 924 of the clusters, which is 46.2% of the total clusters. Finally we evaluate both the clustering and labeling tasks taking 86 randomly selected clusters and on the bases of two native English speaker evaluators? subjective judgment. According to these evaluators, the clustering task has a purity score of 0.7 and 55% of the labels are acceptable with different degree of accuracy.
This book describes the design, implementation and System Verilog simulation of a protocol controller for the Controller Area Network (CAN) 2.0A multi-master serial communication protocol. CAN bus (Controller Area Network) is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer. CAN bus is a message-based protocol, designed specifically for automotive applications but now also used in other areas such as aerospace, industrial automation and medical equipment. Development of CAN bus started originally in 1983 at Robert Bosch GmbH. The protocol was officially released in 1986 at the Society of Automotive Engineers (SAE) congress in Detroit, Michigan. The first CAN controller chips, produced by Intel and Philips, came on the market in 1987. Bosch published the CAN 2.0 specification in 1991.
Design And Development of Microcontroller using re-configurable Media (FPGA) covers most of the flavored shades of B.S Electronics curriculum, it encompasses software tools, and exposed us to techniques of latest digital design. The indispensible advantage of using FPGAs is that numerous logical modules can be integrated onto a single silicon wafer. We incorporated in this project the use of hardware description languages (HDL) such as Verilog. We designed the microcontroller using Veilog HDL. We also simulated the design by using Test Bench of Xilinx project Navigator and also by the means of Model Sim. The simulation results that were achieved are also available.
This book presents the design of digital logic circuits using carbon nanotube field effect transistors (CNTFET). CNTFET is a promising device in the nanometer regime which utilizes a semiconducting carbon nanotube (CNT) channel between the source and drain terminals. Due to the excellent electrical properties of CNT it can offer very high speed integrated circuits. Starting with the basics of CNT and CNTFET this book discusses the modeling of CNTFET using Verilog-AMS language. The design of the basic logic gates is presented. The designs are simulated to verify their functionality and extract the speed and power performances. The design of reconfigurable logic circuits using transmission gate based logic is also presented. A ring oscillator circuit has been designed using CNTFET and it is found that the circuit can operate at very high frequency of 114 GHz.
