The x-Kernel: An Architecture for Implementing Network Protocols

by Norman C. Hutchinson, Larry L. Peterson - IEEE Transactions on Software Engineering , 1991
"... This paper describes a new operating system kernel, called the x-kernel, that provides an explicit architecture for constructing and composing network protocols. Our experience implementing and evaluating several protocols in the x-kernel shows that this architecture is both general enough to acc ..."

to accommodate a wide range of protocols, yet efficient enough to perform competitively with less structured operating systems. 1 Introduction Network software is at the heart of any distributed system. It manages the communication hardware that connects the processors in the system and it defines

Power Analysis of Embedded Software: A First Step towards Software Power Minimization

by Vivek Tiwari, Sharad Malik, Andrew Wolfe , 1994
"... Embedded computer systems are characterized by the presence ofadedicated processor and the software that runs on it. Power constraints are increasingly becoming the critical component of the design speci cation of these systems. At present, however, power analysis tools can only be applied at the lo ..."

Performance Analysis of Embedded Software Using Implicit Path Enumeration

by Yau-Tsun Steven Li, Sharad Malik , 1995
"... Embedded computer systems are characterized by the presence of a processor running application specific software. A large number of these systems must satisfy real-time constraints. This paper examines the problem of determining the bound on the running time of a given program on a given processor. ..."

Automated Whitebox Fuzz Testing

by Patrice Godefroid, Michael Y. Levin, David Molnar
"... Fuzz testing is an effective technique for finding security vulnerabilities in software. Traditionally, fuzz testing tools apply random mutations to well-formed inputs of a program and test the resulting values. We present an alternative whitebox fuzz testing approach inspired by recent advances in ..."

, SAGE has already discovered 30+ new bugs in large shipped Windows applications including image processors, media players, and file decoders. Several of these bugs are potentially exploitable memory access violations.

Instruction level power analysis and optimization of software

by Vivek Tiwari, Sharad Malik, Andrew Wolfe, Mike Tien-chien Lee - Journal of VLSI Signal Processing , 1996
"... Abstract. The increasing popularity of power constrained mobile computers and embedded computing applications drives the need for analyzing and optimizing power in all the components of a system. Software constitutes a major component of today's systems, and its role is projected togrow even fu ..."

Event-Triggered Real-Time Scheduling of Stabilizing Control Tasks

by Paulo Tabuada, Senior Member
"... Abstract—In this note, we revisit the problem of scheduling stabilizing control tasks on embedded processors. We start from the paradigm that a real-time scheduler could be regarded as a feedback controller that decides which task is executed at any given instant. This controller has for objective g ..."

Modeling and Description of Embedded Processors for the Development of Software Tools

by Wei Qin , 2004
"... Increasing design and manufacturing costs are prompting a shift in electronic design from hardwired application-specific integrated circuits (ASICs) to the use of software on programmable platforms. In order to minimize the power and performance over-head of such platforms, domain or application-spe ..."

-specific processors have been used. The development of such processors requires not only traditional electronic design automation tools but also processor-specific software tools such as compilers and in-struction set simulators. In early development stages when multiple processor design points are explored

Power Analysis and Minimization Techniques for Embedded DSP Software

by Mike Tien-chien Lee, Vivek Tiwari, Sharad Malik, Masahiro Fujita , 1996
"... Power is becoming a critical constraint for designing embedded applications. Current power analysis techniques based on circuit-level or architectural-level simulation are either impractical or inaccurate to estimate the power cost for a given piece of application software. In this paper, an instruc ..."
