Some of these applications includes: random logic, bioinformatics, video and image processing, device controllers, communication encoding, modulation, and filtering, limited size systems with RAM blocks, and many more. For example, for video and image processing application it is very difficult and time consuming to use traditional HDL languages, so it’s obligatory to search for other efficient, synthesis tools to implement your design. The question is what is the best comparable language or tool to implement desired application. Also this research is very helpful for language developers to know strength points, weakness points, ease of use and efficiency of each tool or language. This research faced many challenges one of them is that there is no complete reference of all FPGA languages and tools, also available references and guides are few and almost not good. Searching for a simple example to learn some of these tools or languages would be a time consuming. This paper represents a review study or guide of almost all PLD's languages, interpreters and tools that can be used for programming, simulating and synthesizing PLD's for analog, digital & mixed signals and systems supported with simple examples.

  • Reconfigurable Computing in the New Age of Parallelism
    Reconfigurable Computing in the New Age of Parallelism Walid Najjar and Jason Villarreal Department of Computer Science and Engineering University of California Riverside Riverside, CA 92521, USA {najjar,villarre}@cs.ucr.edu Abstract. Reconfigurable computing is an emerging paradigm enabled by the growth in size and speed of FPGAs. In this paper we discuss its place in the evolution of computing as a technology as well as the role it can play in the cur- rent technology outlook. We discuss the evolution of ROCCC (Riverside Opti- mizing Compiler for Configurable Computing) in this context. Keywords: Reconfigurable computing, FPGAs. 1 Introduction Reconfigurable computing (RC) has emerged in recent years as a novel computing paradigm most often proposed as complementing traditional CPU-based computing. This paper is an attempt to situate this computing model in the historical evolution of computing in general over the past half century and in doing so define the parameters of its viability, its potentials and the challenges it faces. In this section we briefly summarize the main factors that have contributed to the current rise of RC as a computing paradigm. The RC model, its potentials and chal- lenges are described in Section 2. Section 3 describes the ROCCC 2.0 (Riverside Optimizing Compiler for Configurable Computing), a C to HDL compilation tool who objective is to raise the programming abstraction level for RC while providing the user with both a top down and a bottom-up approach to designing FPGA-based code accelerators. 1.1 The Role of the von Neumann Model Over a little more than half a century, computing has emerged from non-existence, as a technology, to being a major component in the world’s economy.

    Hardware description language - Wikipedia, the free encyclopedia 페이지 1 / 11 Hardware description language From Wikipedia, the free encyclopedia In electronics, a hardware description language or HDL is any language from a class of computer languages, specification languages, or modeling languages for formal description and design of electronic circuits, and most-commonly, digital logic. It can describe the circuit's operation, its design and organization, and tests to verify its operation by means of simulation.[citation needed] HDLs are standard text-based expressions of the spatial and temporal structure and behaviour of electronic systems. Like concurrent programming languages, HDL syntax and semantics includes explicit notations for expressing concurrency. However, in contrast to most software programming languages, HDLs also include an explicit notion of time, which is a primary attribute of hardware. Languages whose only characteristic is to express circuit connectivity between a hierarchy of blocks are properly classified as netlist languages used on electric computer-aided design (CAD). HDLs are used to write executable specifications of some piece of hardware. A simulation program, designed to implement the underlying semantics of the language statements, coupled with simulating the progress of time, provides the hardware designer with the ability to model a piece of hardware before it is created physically. It is this executability that gives HDLs the illusion of being programming languages, when they are more-precisely classed as specification languages or modeling languages. Simulators capable of supporting discrete-event (digital) and continuous-time (analog) modeling exist, and HDLs targeted for each are available. It is certainly possible to represent hardware semantics using traditional programming languages such as C++, although to function such programs must be augmented with extensive and unwieldy class libraries.

  • An Automated Flow to Generate Hardware Computing Nodes from C for an FPGA-Based MPI Computing Network
    An Automated Flow to Generate Hardware Computing Nodes from C for an FPGA-Based MPI Computing Network by D.Y. Wang A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF BACHELOR OF APPLIED SCIENCE DIVISION OF ENGINEERING SCIENCE FACULTY OF APPLIED SCIENCE AND ENGINEERING UNIVERSITY OF TORONTO Supervisor: Paul Chow April 2008 Abstract Recently there have been initiatives from both the industry and academia to explore the use of FPGA-based application-specific hardware acceleration in high-performance computing platforms as traditional supercomputers based on clusters of generic CPUs fail to scale to meet the growing demand of computation-intensive applications due to limitations in power consumption and costs. Research has shown that a heteroge- neous system built on FPGAs exclusively that uses a combination of different types of computing nodes including embedded processors and application-specific hardware accelerators is a scalable way to use FPGAs for high-performance computing. An ex- ample of such a system is the TMD [11], which also uses a message-passing network to connect the computing nodes. However, the difficulty in designing high-speed hardware modules efficiently from software descriptions is preventing FPGA-based systems from being widely adopted by software developers. In this project, an auto- mated tool flow is proposed to fill this gap. The AUTO flow is developed to auto- matically generate a hardware computing node from a C program that can be used directly in the TMD system. As an example application, a Jacobi heat-equation solver is implemented in a TMD system where a soft processor is replaced by a hardware computing node generated using the AUTO flow.

    Techniques for Enabling In-System Observation-based Debug of High-Level Synthesis Circuits on FPGAs by Jeffrey Goeders BASc Computer Engineering, University Toronto, 2010 MASc Computer Engineering, The University of British Columbia, 2012 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF Doctor of Philosophy in THE FACULTY OF GRADUATE AND POSTDOCTORAL STUDIES (Electrical and Computer Engineering) The University of British Columbia (Vancouver) September 2016 c Jeffrey Goeders, 2016 Abstract High-level synthesis (HLS) is a rapidly growing design methodology that allows designers to create digital circuits using a software-like specification language. HLS promises to increase the productivity of hardware designers in the face of steadily increasing circuit sizes, and broaden the availability of hardware acceleration, allowing software designers to reap the benefits of hardware implementation. One roadblock to HLS adoption is the lack of an in-system debugging infrastructure. Existing debug technologies are limited to software emulation and cannot be used to find bugs that only occur in the final operating environment. This dissertation investigates techniques for observing HLS circuits, allowing designers to debug the circuit in the context of the original source code, while it executes at-speed in the normal operating environment. This dissertation is comprised of four major contributions toward this goal. First, we develop a debugging framework that provides users with a basic software-like debug experience, including single- stepping, breakpoints and variable inspection. This is accomplished by automatically inserting special- ized debug instrumentation into the user’s circuit, allowing an external debugger to observe the circuit. Debugging at-speed is made possible by recording circuit execution in on-chip memories and retrieving the data for offline analysis.
