Embedded System Design: A Unified Hardware/Software Approach

This book introduces embedded system design using a modern approach. Modern design requires a designer to have a unified view of software and hardware, seeing them not as completely different domains, but rather as two implementation options along a continuum of options varying in their design metrics (cost, performance, power, flexibility, etc.).

Specification and Design of Embedded Systems

IT, 1998

With the rising complexity of digital designs and the deep sub-micron era right ahead, the speci cation and the design of embedded systems has to move to higher levels of abstraction. Co-design, the design of systems involving both hardware and software parts, consists of a set of re nement tasks that map an abstract speci cation of the design onto the intended system architecture. This article describes a generic co-design methodology including speci cation of the design at a high level of abstraction and step-wise re nement.

A framework for system-level modeling and simulation of embedded systems architectures

EURASIP Journal on …, 2007

The high complexity of modern embedded systems impels designers of such systems to model and simulate system components and their interactions in the early design stages. It is therefore essential to develop good tools for exploring a wide range of design choices at these early stages, where the design space is very large. This paper provides an overview of our system-level modeling and simulation environment, Sesame, which aims at efficient design space exploration of embedded multimedia system architectures. Taking Sesame as a basis, we discuss many important key concepts in early systems evaluation, such as Y-chart-based systems modeling, design space pruning and exploration, trace-driven cosimulation, and model calibration.

A Systematic Approach to Exploring Embedded System Architectures at Multiple Abstraction Levels

IEEE Transactions on Computers, 2006

The sheer complexity of today's embedded systems forces designers to start with modeling and simulating system components and their interactions in the very early design stages. It is therefore imperative to have good tools for exploring a wide range of design choices, especially during the early design stages, where the design space is at its largest. This paper presents an overview of the Sesame framework, which provides high-level modeling and simulation methods and tools for system-level performance evaluation and exploration of heterogeneous embedded systems. More specifically, we describe Sesame's modeling methodology and trajectory. It takes a designer systematically along the path from selecting candidate architectures, using analytical modeling and multiobjective optimization, to simulating these candidate architectures with our system-level simulation environment. This simulation environment subsequently allows for architectural exploration at different levels of abstraction while maintaining highlevel and architecture-independent application specifications. We illustrate all these aspects using a case study in which we traverse Sesame's exploration trajectory for a Motion-JPEG encoder application.

Abstract, Multifaceted Modeling of Embedded Processors for System Level Design

2007 Asia and South Pacific Design Automation Conference, 2007

Embedded software is playing an increasing role in todays SoC designs. It allows a flexible adaptation to evolving standards and to customer specific demands. As software emerges more and more as a design bottleneck, early, fast, and accurate simulation of software becomes crucial. Therefore, an efficient modeling of programmable processors at high levels of abstraction is required. In this article, we focus on abstraction of computation and describe our abstract modeling of embedded processors. We combine the computation modeling with task scheduling support and accurate interrupt handling into a versatile, multi-faceted processor model with varying levels of features. Incorporating the abstract processor model into a communication model, we achieve fast co-simulation of a complete custom target architecture for a system level design exploration. We demonstrate the effectiveness of our approach using an industrial strength telecommunication example executing on a Motorola DSP architecture. Our results indicate the tremendous value of abstract processor modeling. Different feature levels achieve a simulation speedup of up to 6600 times with an error of less than 8% over a ISS based simulation. On the other hand, our full featured model exhibits a 3% error in simulated timing with a 1800 times speedup.
