Available in PDF, EPUB and Kindle. Book excerpt: Digital signal and image processing and other real time applications involve simple but large amounts of computations. These problems have an enormous amount of inherent parallelism and demand high speed computation. Conventional computers do not possess these characteristics and this had led to the development of new architectural concepts. Among the new architectures, the systolic and wavefront arrays processors have gained a lot of attention because of their high processing bandwidth. The systolic arrays combine massive pipelining with parallelism. There is one problem with this approach of designing application specific chips wherein each of these chips is capable of processing a single algorithm. A number of real time applications require more than one algorithm to be executed for a complete solution. . One solution to the above problem is to develop reconfigurable array structures. One notable proposal is the Confiurable Highly Parallel Computer (CHiP) which is capable of reconfiguring the array to suit different interconnection schemes. In this thesis, the CHiP has been adapted to suit a family of systolic architectures. The dynamically Configurable Systolic Array proposed is designed to accommodate the linear configuration to solve convolution and polynomial multiplication, a square configuration to solve full matrix multiplication and a hexagonal array for band matrix multiplication. The array is a 2-dimensional array arranged in a square grid and functions as an attached processor to a host. Each processor in the array is connected only to it's immediate neighbours and all external communication is only through the edge processors. The actual interconnection patterns are implemented by a set of tristate drivers that are part of the communication links between neighbouring processors. The drivers are controlled by the controller and patterns are determined by the control signals generated. The arithmetic unit is a simple multiplier along with an adder capable of executing the inner product computation common to many signal and image processing applications. The array has been built on a Genesil Silicon Compiler using 2-micron CMOS technology. The three array configurations have been successfully simulated and tested. The algorithms have been executed in times that closely match the theoretical times. More importantly, the feasibility of building a single chip to implement a number of algorithms has been demonstrated and paves the way for further research in this area.

Available in PDF, EPUB and Kindle. Book excerpt: Circuits and architectures have become more complex in terms of structure, interconnection topology, and data flow. Design correctness has become increasingly significant, as errors in design may result in strenuous debugging, or even in the repetition of a costly manufacturing process. Although circuit simulation has been used traditionally and widely as the technique for checking hardware and architectural designs, it does not guarantee the conformity of designs to specifications. Formal methods therefore become vital in guaranteeing the correctness of designs and have thus received a significant amount of attention in the CAD industry today.This book presents a formal method for specifying and verifying the correctness of systolic array designs. Such architectures are commonly found in the form of accelerators for digital signal, image, and video processing. These arrays can be quite complicated in topology and data flow. In the book, a formalism called STA is defined for these kinds of dynamic environments, with a survey of related techniques. A framework for specification and verification is established. Formal verification techniques to check the correctness of the systolic networks with respect to the algorithmic level specifications are explained. The book also presents a Prolog-based formal design verifier (named VSTA), developed to automate the verification process, as using a general purpose theorem prover is usually extremely time-consuming. Several application examples are included in the book to illustrate how formal techniques and the verifier can be used to automate proofs.

Available in PDF, EPUB and Kindle. Book excerpt: Field programmable grid arrays (FPGA) are increasingly being adopted as the primary on-board computing system for autonomous deep space vehicles. There is a need to support several complex applications for navigation and image processing in a rapidly responsive on-board FPGA-based computer. This requires exploring and combining several design concepts such as systolic arrays, hardware-software partitioning, and partial dynamic reconfiguration. A microprocessor/co-processor design that can accelerate two single precision floating-point algorithms, extended Kalman filter and a discrete wavelet transform, is presented. This research makes three key contributions. (i) A polymorphic systolic array framework comprising of reconfigurable partial region-based sockets to accelerate algorithms amenable to being mapped onto linear systolic arrays. When implemented on a low end Xilinx Virtex4 SX35 FPGA the design provides a speedup of at least 4.18x and 6.61x over a state of the art microprocessor used in spacecraft systems for the extended Kalman filter and discrete wavelet transform algorithms, respectively. (ii) Switchboxes to enable communication between static and partial reconfigurable regions and a simple protocol to enable schedule changes when a socket's contents are dynamically reconfigured to alter the concurrency of the participating systolic arrays. (iii) A hybrid partial dynamic reconfiguration method that combines Xilinx early access partial reconfiguration, on-chip bitstream decompression, and bitstream relocation to enable fast scaling of systolic arrays on the PolySAF. This technique provided a 2.7x improvement in reconfiguration time compared to an o-chip partial reconfiguration technique that used a Flash card on the FPGA board, and a 44% improvement in BRAM usage compared to not using compression.

Download or read book Parallel Processing on VLSI Arrays written by Josef A. Nossek and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Guest Editor: JOSEF A. NOSSEK This is a special issue of the Journal of VLSI Signal Processing comprising eight contributions invited for publica tion on the basis of novel work presented in a special session on "Parallel Processing on VLSI Arrays" at the International Symposium on Circuits and Systems (ISCAS) held in New Orleans in May 1990. Massive parallelism to cope with high-speed requirements stemming from real-time applications and the restrictions in architectural and circuit design, such as regularity and local connectedness, brought about by the VLSI technology are the key questions addressed in these eight papers. They can be grouped into three subsections elaborating on: • Simulation of continuous physical systems, i. e. , numerically solving partial differential equations. • Neural architectures for image processing and pattern recognition. • Systolic architectures for implementing regular and irregular algorithms in VLSI technology. The paper by A. Fettweis and O. Nitsche advocates a signal processing approach for the numerical integration of partial differential equations (PD Es). It is based on the principles of multidimensional wave digital filters (MDWDFs) thereby preserving the passivity of energy dissipating physical systems. It is particularly suited for systems ofPDEs involving time and finite propagation speed. The basic ideas are explained using Maxwell's equa tions as a vehicle for the derivation of a multidimensional equivalent circuit representing the spatially infinitely extended arrangement with only very few circuit elements.

This book was released on 2012-12-06 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 34 (thesis year 1989) a total of 13,377 theses titles from 26 Canadian and 184 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 34 reports theses submitted in 1989, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: Dynamic Reconfiguration: Architectures and Algorithms offers a comprehensive treatment of dynamically reconfigurable computer architectures and algorithms for them. The coverage is broad starting from fundamental algorithmic techniques, ranging across algorithms for a wide array of problems and applications, to simulations between models. The presentation employs a single reconfigurable model (the reconfigurable mesh) for most algorithms, to enable the reader to distill key ideas without the cumbersome details of a myriad of models. In addition to algorithms, the book discusses topics that provide a better understanding of dynamic reconfiguration such as scalability and computational power, and more recent advances such as optical models, run-time reconfiguration (on FPGA and related platforms), and implementing dynamic reconfiguration. The book, featuring many examples and a large set of exercises, is an excellent textbook or reference for a graduate course. It is also a useful reference to researchers and system developers in the area.

Download or read book Designing SOCs with Configured Cores written by Steve Leibson and published by Elsevier. This book was released on 2006-08-15 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microprocessor cores used for SOC design are the direct descendents of Intel’s original 4004 microprocessor. Just as packaged microprocessor ICs vary widely in their attributes, so do microprocessors packaged as IP cores. However, SOC designers still compare and select processor cores the way they previously compared and selected packaged microprocessor ICs. The big problem with this selection method is that it assumes that the laws of the microprocessor universe have remained unchanged for decades. This assumption is no longer valid. Processor cores for SOC designs can be far more plastic than microprocessor ICs for board-level system designs. Shaping these cores for specific applications produces much better processor efficiency and much lower system clock rates. Together, Tensilica’s Xtensa and Diamond processor cores constitute a family of software-compatible microprocessors covering an extremely wide performance range from simple control processors, to DSPs, to 3-way superscalar processors. Yet all of these processors use the same software-development tools so that programmers familiar with one processor in the family can easily switch to another. This book emphasizes a processor-centric MPSOC (multiple-processor SOC) design style shaped by the realities of the 21st-century and nanometer silicon. It advocates the assignment of tasks to firmware-controlled processors whenever possible to maximize SOC flexibility, cut power dissipation, reduce the size and number of hand-built logic blocks, shrink the associated verification effort, and minimize the overall design risk. · An essential, no-nonsense guide to the design of 21st-century mega-gate SOCs using nanometer silicon. · Discusses today's key issues affecting SOC design, based on author's decades of personal experience in developing large digital systems as a design engineer while working at Hewlett-Packard's Desktop Computer Division and at EDA workstation pioneer Cadnetix, and covering such topics as an award-winning technology journalist and editor-in-chief for EDN magazine and the Microprocessor Report. · Explores conventionally accepted boundaries and perceived limits of processor-based system design and then explodes these artificial constraints through a fresh outlook on and discussion of the special abilities of processor cores designed specifically for SOC design. · Thorough exploration of the evolution of processors and processor cores used for ASIC and SOC design with a look at where the industry has come from, and where it's going. · Easy-to-understand explanations of the capabilities of configurable and extensible processor cores through a detailed examination of Tensilica's configurable, extensible Xtensa processor core and six pre-configured Diamond cores. · The most comprehensive assessment available of the practical aspects of configuring and using multiple processor cores to achieve very difficult and ambitious SOC price, performance, and power design goals.

Available in PDF, EPUB and Kindle. Book excerpt: Covers the significant embedded computing technologies highlighting their applications in wireless communication and computing power An embedded system is a computer system designed for specific control functions within a larger system often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. Presented in three parts, Embedded Systems: Hardware, Design, and Implementation provides readers with an immersive introduction to this rapidly growing segment of the computer industry. Acknowledging the fact that embedded systems control many of today's most common devices such as smart phones, PC tablets, as well as hardware embedded in cars, TVs, and even refrigerators and heating systems, the book starts with a basic introduction to embedded computing systems. It hones in on system-on-a-chip (SoC), multiprocessor system-on-chip (MPSoC), and network-on-chip (NoC). It then covers on-chip integration of software and custom hardware accelerators, as well as fabric flexibility, custom architectures, and the multiple I/O standards that facilitate PCB integration. Next, it focuses on the technologies associated with embedded computing systems, going over the basics of field-programmable gate array (FPGA), digital signal processing (DSP) and application-specific integrated circuit (ASIC) technology, architectural support for on-chip integration of custom accelerators with processors, and O/S support for these systems. Finally, it offers full details on architecture, testability, and computer-aided design (CAD) support for embedded systems, soft processors, heterogeneous resources, and on-chip storage before concluding with coverage of software support in particular, O/S Linux. Embedded Systems: Hardware, Design, and Implementation is an ideal book for design engineers looking to optimize and reduce the size and cost of embedded system products and increase their reliability and performance.
