LETTER FROM THE EDITOR Thank You for Making Xilinx Number One Ever have one of those days where you’re working hard, nose to the grindstone, striving to make sure EDITOR IN CHIEF Carlis Collins your latest project is on time and on target; and then suddenly out of nowhere, you overhear some- [email protected] 408-879-4519 one complimenting your efforts? It’s not a comment that you solicited, but independently you find out that all of your hard work is recognized as the best among your peers and you’re headed in the MANAGING EDITOR Forrest Couch [email protected] right direction. 408-879-5270 CMP Media LLC, the parent company of EETimes, just dropped quite a few kudos on the Xilinx ASSISTANT MANAGING EDITOR Charmaine Cooper Hussain Edoorstep. Most of you know that every year CMP conducts a PCB and IC electronic design tool industry survey to sample the engineering community’s view on design tool providers. This year, at the XCELL ONLINE EDITOR Tom Pyles [email protected] 2004 Design Automation Conference, CMP announced the results of their first FPGA vendor survey. 720-652-3883 The ratings are striking. In 21 out of 22 categories measuring everything from best pre-sales support ADVERTISING SALES Dan Teie to brand and tool awareness, from most ethical company to customer loyalty, FPGA designers chose 1-800-493-5551 Xilinx as the top FPGA vendor. We received the highest rankings in best after-sales support, best ART DIRECTOR Scott Blair documentation, current technology leader, technology leader in three years, clear vision of the future, best integration with other vendors’ tools, well-managed company, and more. We were also able to hear the industry concerns. Respondents cited the accuracy and integrity of FPGA tools as their biggest design issue, followed closely by functional verification, timing closure, and the Xcell journal ability of those tools to easily handle complex designs. They also said that the majority of their design Xilinx, Inc. time was spent in place and route, synthesis, and HDL simulation, followed by timing analysis and 2100 Logic Drive San Jose, CA 95124-3400 floorplanning. One-third of the respondents also use formal verification, while almost half regularly Phone: 408-559-7778 FAX: 408-879-4780 use signal integrity and C language system-level tools. ©2004 Xilinx, Inc.

Therefore, after two years of growth, an overbuilding of capacity will likely occur, with another market correction in 2006. This is a normal and predictable cycle; it’s the way our industry usually works. These capacity-driven recessions tend to be shallow and short – the last one was in 1996 and lasted about 18 months. For Xilinx® dur- ing that period, we had a few negative growth quarters, with an overall 1% growth. The market recovery is still fragile, driven primarily by the U.S. and China.

    International Journal of Computer Science & Information Technology (IJCSIT) Vol 4, No 2, April 2012 MPP SOCGEN: A FRAMEWORK FOR AUTOMATIC GENERATION OF MPP SOC ARCHITECTURE Emna Kallel, Yassine Aoudni, Mouna Baklouti and Mohamed Abid Electrical department, Computer Embedded System Laboratory, ENIS School, Sfax, Tunisia ABSTRACT Automatic code generation is a standard method in software engineering since it improves the code consistency and reduces the overall development time. In this context, this paper presents a design flow for automatic VHDL code generation of mppSoC (massively parallel processing System-on-Chip) configuration. Indeed, depending on the application requirements, a framework of Netbeans Platform Software Tool named MppSoCGEN was developed in order to accelerate the design process of complex mppSoC. Starting from an architecture parameters design, VHDL code will be automatically generated using parsing method. Configuration rules are proposed to have a correct and valid VHDL syntax configuration. Finally, an automatic generation of Processor Elements and network topologies models of mppSoC architecture will be done for Stratix II device family. Our framework improves its flexibility on Netbeans 5.5 version and centrino duo Core 2GHz with 22 Kbytes and 3 seconds average runtime. Experimental results for reduction algorithm validate our MppSoCGEN design flow and demonstrate the efficiency of generated architectures. KEYWORD MppSoC, Automatic code generation; mppSoC configuration;parsing ; MppSoCGEN; 1. INTRODUCTION Parallel machines are most often used in many modern applications that need regular parallel algorithms and high computing resources, such as image processing and signal processing. Massively parallel architectures, in particular Single Instruction Multiple Data (SIMD) systems, have shown to be powerful executers for data-intensive applications [1].

    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.

  • Automatic Instruction-Set Architecture Synthesis for VLIW Processor Cores in the ASAM Project
    Automatic Instruction-set Architecture Synthesis for VLIW Processor Cores in the ASAM Project Roel Jordansa,∗, Lech J´o´zwiaka, Henk Corporaala, Rosilde Corvinob aEindhoven University of Technology, Postbus 513, 5600MB Eindhoven, The Netherlands bIntel Benelux B.V., Capronilaan 37, 1119NG Schiphol-Rijk Abstract The design of high-performance application-specific multi-core processor systems still is a time consuming task which involves many manual steps and decisions that need to be performed by experienced design engineers. The ASAM project sought to change this by proposing an auto- matic architecture synthesis and mapping flow aimed at the design of such application specific instruction-set processor (ASIP) systems. The ASAM flow separated the design problem into two cooperating exploration levels, known as the macro-level and micro-level exploration. This paper presents an overview of the micro-level exploration level, which is concerned with the anal- ysis and design of individual processors within the overall multi-core design starting at the initial exploration stages but continuing up to the selection of the final design of the individual proces- sors within the system. The designed processors use a combination of very-long instruction-word (VLIW), single-instruction multiple-data (SIMD), and complex custom DSP-like operations in or- der to provide an area- and energy-efficient and high-performance execution of the program parts assigned to the processor node. In this paper we present an overview of how the micro-level design space exploration interacts with the macro-level, how early performance estimates are used within the ASAM flow to determine the tasks executed by each processor node, and how an initial processor design is then proposed and refined into a highly specialized VLIW ASIP.
