  • A System-Level Synthetic Circuit Generator for FPGA Architectural Analysis
    A System-Level Synthetic Circuit Generator for FPGA Architectural Analysis by Cindy Mark B.A.Sc., Queen’s University, 2006 A THESIS SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF Master of Applied Science in The Faculty of Graduate Studies (Electrical and Computer Engineering) The University Of British Columbia (Vancouver) November, 2008 c Cindy Mark 2008 Abstract Architectural research for Field-Programmable Gate Arrays (FPGAs) tends to use an experimental approach. The benchmark circuits are used not only to compare different architectures, but also to ensure that the FPGA is sufficiently flexible to implement the desired variety of circuits. The most common benchmark circuits used for architectural research are circuits from the Microelectronics Center of North Carolina (MCNC). These circuits are small; they occupy less than 3% [5] of the largest available commercial FPGA. Moreover, these circuits are more representative of the glue logic circuits that were targets of early devices. This contrasts with the trend towards implementing Systems on Chip (SoCs) on FPGAs where several functional modules are integrated into a single circuit which is mapped onto one device. In this thesis, we develop a synthetic system-level circuit generator that connects pre- existing circuits in a realistic manner to build large netlists that share the characteristics of real SoC circuits. This generator is based on a survey of contemporary circuit designs from industrial and academic sources. We demonstrate that these system-level circuits scale well and that their post-routing characteristics match the results of large pre-existing benchmarks better than the results of circuits from previous synthetic generators.

One reason for not participating is that the companies are selling their processors only to specific customers and are not yet publicly offering those products. Some of the new companies par- ticipating in this year’s directory have recently begun making their processors available to the engineering public. Another type of change occurs when a company acquires another company or another company’s product line. Some of the acquired product lines are no longer available in their current form, such as the MediaQ processors that Nvidia acquired or the Triscend products that Arm acquired.

  • Object-Oriented Development for Reconfigurable Architectures
    Object-Oriented Development for Reconfigurable Architectures Von der Fakultät für Mathematik und Informatik der Technischen Universität Bergakademie Freiberg genehmigte DISSERTATION zur Erlangung des akademischen Grades Doktor Ingenieur Dr.-Ing., vorgelegt von Dipl.-Inf. (FH) Dominik Fröhlich geboren am 19. Februar 1974 Gutachter: Prof. Dr.-Ing. habil. Bernd Steinbach (Freiberg) Prof. Dr.-Ing. Thomas Beierlein (Mittweida) PD Dr.-Ing. habil. Michael Ryba (Osnabrück) Tag der Verleihung: 20. Juni 2007 To my parents. ABSTRACT Reconfigurable hardware architectures have been available now for several years. Yet the application devel- opment for such architectures is still a challenging and error-prone task, since the methods, languages, and tools being used for development are inappropriate to handle the complexity of the problem. This hampers the widespread utilization, despite of the numerous advantages offered by this type of architecture in terms of computational power, flexibility, and cost. This thesis introduces a novel approach that tackles the complexity challenge by raising the level of ab- straction to system-level and increasing the degree of automation. The approach is centered around the paradigms of object-orientation, platforms, and modeling. An application and all platforms being used for its design, implementation, and deployment are modeled with objects using UML and an action language. The application model is then transformed into an implementation, whereby the transformation is steered by the platform models. In this thesis solutions for the relevant problems behind this approach are discussed. It is shown how UML can be used for complete and precise modeling of applications and platforms. Application development is done at the system-level using a set of well-defined, orthogonal platform models.

    NOVATEUR PUBLICATIONS INTERNATIONAL JOURNAL OF INNOVATIONS IN ENGINEERING RESEARCH AND TECHNOLOGY [IJIERT] ISSN: 2394-3696 VOLUME 5, ISSUE 6, June -2018 DESIGN AND DEVELOPMENT OF A SOFT RECONFIGURABLE POWER ELECTRONIC CONTROL PROCESSOR KEVIN S, ER&DCI, CDAC, Trivandrum, [email protected] AJEESH A, Senior Engineer, Power Electronics Group, CDAC, Trivandrum, [email protected] DIVYA D.S, Project Engineer, ER&DCI, CDAC, Trivandrum, [email protected] ABSTRACT This paper proposes to build a soft, platform independent, reconfigurable power electronic control processor in HDL. Currently power electronic control processors are designed with digital signal processors/microcontrollers with limited re-configurability and input-output capabilities, also DSP/microcontrollers suffer processor obsolescence risk. This can be reduced with the use of a reconfigurable control processor design in HDL and implemented on FPGA. Currently FPGA are used along with DSP for glue logic purpose and input-output expansion. So it is economical to use a single FPGA along with a soft core CPU and control modules as hardware accelerators. Some of the soft cores available are licensed and are targeted to a particular FPGA, so a 32 bit soft, reconfigurable power electronic control processor is developed from scratch. I. INTRODUCTION In this paper development of a soft, reconfigurable power electronic control processor is discussed. The conventionally used soft cores in power electronics like NIOS II are highly efficient but they take 8-9 cycles for memory read or write instructions. So to reduce this memory read and write cycles, the need for a soft reconfigurable processor arises. This newly developed soft core is also a FPGA independent one, so that it can be implemented on any available FPGA.

A logic family of monolithic digital integrated circuit devices is a group of electronic logic gates constructed using one of several different designs, usually with compatible logic levels and power supply characteristics within a family. Many logic families were produced as individual components, each containing one or a few related basic logical functions, which could be used as "building-blocks" to create systems or as so-called "glue" to interconnect more complex integrated circuits. A "logic family" may also refer to a set of techniques used to implement logic within VLSI integrated circuits such as central processors, memories, or other complex functions. Some such logic families use static techniques to minimize design complexity. Other such logic families, such as domino logic, use clocked dynamic techniques to minimize size, power consumption, and delay. Before the widespread use of integrated circuits, various solid-state and vacuum-tube logic systems were used but these were never as standardized and interoperable as the integrated-circuit devices.
