customized instruction sets for embedded processors
Design Automation Conference, 1999Co-Authors: Joseph A FisherAbstract:It is generally believed that there will be little more variety in CPU architectures, and thus the design of Instruction-Set Architectures (ISAs) will have no role in the future of embedded CPU design. Nonetheless, it is argued in this paper that architectural variety will soon again become an important topic, with the major motivation being increased performance due to the customization of CPUs to their intended use. Five major barriers that could hinder customization are described, including the problems of existing binaries, toolchain Development and maintenance costs, lost savings/higher chip cost due to the lower volumes of customized processors, added Hardware Development costs, and some factors related to the product Development cycle for embedded products. Each is discussed, along with potential, sometimes surprising, solutions.

high temperature Hardware Development of a 10 kw high temperature high power density three phase ac dc ac sic converter
IEEE Industrial Electronics Magazine, 2013Co-Authors: Puqi Ning, Di Zhang, Rixin Lai, Dong Jiang, F Wang, Dushan Boroyevich, Rolando Burgos, Kamiar J Karimi, Vikram D Immanuel, Eugene SolodovnikAbstract:This article presents the Development and experimental performance of a 10-W, all-silicon carbide (SiC), 250 °C junction temperature, high-powerdensity, three-phase ac-dc-ac converter. The electromagnetic interference filter, thermal system, high-temperature package, and gate drive design are discussed in detail. Tests confirming the feasibility and validating the theoretical basis of the prototype converter system are described. Over the last 20 years, advances in industrial and research efforts in electronic power conversion have steadily been moving toward higher power densities, which has resulted in improvements in converter system performance; reductions in physical size; and reductions in mass, weight, and cost. However, this pushes the limits of the existing control, packaging, and thermal management technology for power converter systems.

An approach to instruction set compiled simulator Development based on a target processor C compiler back-end design
Innovations in Systems and Software Engineering, 2013Co-Authors: Miodrag Djukic, Nenad Cetic, Radovan Obradovic, Miroslav PopovicAbstract:Many instruction set simulation approaches place the retargetability and/or cycle-accuracy as the key features for easier architectural exploration and performance estimation early in the Hardware Development phase. This paper describes an approach in which importance of speed and controllability is placed above the cycle-accuracy and retargetability, thus providing a better platform for software Development. The main idea behind this work is to associate the compiled simulator effort with the Development of the C language compiler for the target embedded processor, using the knowledge related to compilers and reusing some common software elements. Through the prototype design of a compiled simulator for the Cirrus Logic Coyote DSP architecture, many implementation aspects are presented showing that this approach has great potential.

An Approach to Instruction Set Compiled Simulator Development Based on a Target Processor C Compiler Back-End Design
2009 First IEEE Eastern European Conference on the Engineering of Computer Based Systems, 2009Co-Authors: Miodrag Djukic, Nenad Cetic, Radovan Obradovic, Miroslav PopovicAbstract:Many instruction set simulation approaches place the retargetability and/or cycle-accuracy as the key features for easier architectural exploration and performance estimation early in the Hardware Development phase. This paper describes an approach in which importance of speed and controllability is placed above the cycle-accuracy and retargetability, thus providing a better platform for software Development. The main idea behind this work is to try to associate the compiled simulator effort with the Development of the C language compiler for the target embedded processor, using the knowledge from that field of work and reusing some common software elements. Through the prototype design of a compiled simulator for the Cirrus Logic Coyote DSP architecture, many implementation aspects are presented proving that this approach has a great potential.

ControlFlag: A Self-supervised Idiosyncratic Pattern Detection System for Software Control Structures
2021Co-Authors: Hasabnis Niranjan, Gottschlich JustinAbstract:Software debugging has been shown to utilize upwards of 50% of developers' time. Machine programming, the field concerned with the automation of software (and Hardware) Development, has recently made progress in both research and production-quality automated debugging systems. In this paper, we present ControlFlag, a system that detects possible idiosyncratic violations in software control structures. ControlFlag also suggests possible corrections in the event a true error is detected. A novelty of ControlFlag is that it is entirely self-supervised; that is, it requires no labels to learn about the potential idiosyncratic programming pattern violations. In addition to presenting ControlFlag's design, we also provide an abbreviated experimental evaluation.Comment: 12 pages, 3 figures, 2 table

getting started with open Hardware Development and control of microfluidic devices
Electrophoresis, 2014Co-Authors: Eric Tavares Da Costa, Maria F Mora, Peter Willis, Claudimir Lucio Do Lago, Hong Jiao, Carlos D GarciaAbstract:Understanding basic concepts of electronics and computer programming allows researchers to get the most out of the equipment found in their laboratories. Although a number of platforms have been specifically designed for the general public and are supported by a vast array of on-line tutorials, this subject is not normally included in university chemistry curricula. Aiming to provide the basic concepts of Hardware and software, this article is focused on the design and use of a simple module to control a series of PDMS-based valves. The module is based on a low-cost microprocessor (Teensy) and open-source software (Arduino). The microvalves were fabricated using thin sheets of PDMS and patterned using CO2 laser engraving, providing a simple and efficient way to fabricate devices without the traditional photolithographic process or facilities. Synchronization of valve control enabled the Development of two simple devices to perform injection (1.6 ± 0.4 μL/stroke) and mixing of different solutions. Furthermore, a practical demonstration of the utility of this system for microscale chemical sample handling and analysis was achieved performing an on-chip acid-base titration, followed by conductivity detection with an open-source low-cost detection system. Overall, the system provided a very reproducible (98%) platform to perform fluid delivery at the microfluidic scale.
