Book Description
Memory Architecture Exploration for Programmable Embedded Systems addresses efficient exploration of alternative memory architectures, assisted by a "compiler-in-the-loop" that allows effective matching of the target application to the processor-memory architecture. This new approach for memory architecture exploration replaces the traditional black-box view of the memory system and allows for aggressive co-optimization of the programmable processor together with a customized memory system. The book concludes with a set of experiments demonstrating the utility of this exploration approach. The authors perform architecture and compiler exploration for a set of large, real-life benchmarks, uncovering promising memory configurations from different perspectives, such as cost, performance and power.

Book Description
It is widely acknowledged that the cost of validation and testing comprises a s- nificant percentage of the overall development costs for electronic systems today, and is expected to escalate sharply in the future. Many studies have shown that up to 70% of the design development time and resources are spent on functional verification. Functional errors manifest themselves very early in the design flow, and unless they are detected up front, they can result in severe consequence- both financially and from a safety viewpoint. Indeed, several recent instances of high-profile functional errors (e. g. , the Pentium FDIV bug) have resulted in - creased attention paid to verifying the functional correctness of designs. Recent efforts have proposed augmenting the traditional RTL simulation-based validation methodology with formal techniques in an attempt to uncover hard-to-find c- ner cases, with the goal of trying to reach RTL functional verification closure. However, what is often not highlighted is the fact that in spite of the tremendous time and effort put into such efforts at the RTL and lower levels of abstraction, the complexity of contemporary embedded systems makes it difficult to guarantee functional correctness at the system level under all possible operational scenarios. The problem is exacerbated in current System-on-Chip (SOC) design meth- ologies that employ Intellectual Property (IP) blocks composed of processor cores, coprocessors, and memory subsystems. Functional verification becomes one of the major bottlenecks in the design of such systems.

Book Description
Data Access and Storage Management for Embedded Programmable Processors gives an overview of the state-of-the-art in system-level data access and storage management for embedded programmable processors. The targeted application domain covers complex embedded real-time multi-media and communication applications. Many of these applications are data-dominated in the sense that their cost related aspects, namely power consumption and footprint are heavily influenced (if not dominated) by the data access and storage aspects. The material is mainly based on research at IMEC in this area in the period 1996-2001. In order to deal with the stringent timing requirements and the data dominated characteristics of this domain, we have adopted a target architecture style that is compatible with modern embedded processors, and we have developed a systematic step-wise methodology to make the exploration and optimization of such applications feasible in a source-to-source precompilation approach.

Book Description
AbstractToday's feature-rich multimedia products require embedded system solution with complexSystem-on-Chip (SoC) to meet market expectations of high performance at low cost andlower energy consumption. SoCs are complex designs with multiple embedded processors,memory subsystems, and application specific peripherals. The memory architecture ofembedded SoCs strongly influences the area, power and performance of the entire system.Further, the memory subsystem constitutes a major part (typically up to 70%) of thesilicon area for the current day SoC.The on-chip memory organization of embedded processors varies widely from oneSoC to another, depending on the application and market segment for which the SoC isdeployed. There is a wide variety of choices available for the embedded designers, startingfrom simple on-chip SPRAM based architecture to more complex cache-SPRAM basedhybrid architecture. The performance of a memory architecture also depends on howthe data variables of the application are placed in the memory. There are multiple datalayouts for each memory architecture that are efficient from a power and performanceviewpoint. Further, the designer would be interested in multiple optimal design pointsto address various market segments. Hence a memory architecture exploration for anembedded system involves evaluating a large design space in the order of 100,000 ofdesign points and each design points having several tens of thousands of data layouts.Due to its large impact on system performance parameters, the memory architecture isoften hand-crafted by experienced designers exploring a very small subset of this designspace. The vast memory design space prohibits any possibility for a manual analysis.In this work, we propose an automated framework for on-chip memory architectureexploration. Our proposed framework integrates memory architecture exploration anddata layout to search the design space efficiently. While the memory exploration selectsspecific memory architectures, the data layout efficiently maps the given application onto the memory architecture under consideration and thus helps in evaluating the memoryarchitecture. The proposed memory exploration framework works at both logical andphysical memory architecture level. Our work addresses on-chip memory architecture forDSP processors that is organized as multiple memory banks, with each back can be asingle/dual port banks and with non-uniform bank sizes. Further, our work also addressmemory architecture exploration for on-chip memory architectures that is SPRAM andcache based. Our proposed method is based on multi-objective Genetic Algorithm basedand outputs several hundred Pareto-optimal design solutions that are interesting from aarea, power and performance viewpoints within a few hours of running on a standarddesktop configuration.

Book Description
Considered a standard industry resource, the Embedded Systems Handbook provided researchers and technicians with the authoritative information needed to launch a wealth of diverse applications, including those in automotive electronics, industrial automated systems, and building automation and control. Now a new resource is required to report on current developments and provide a technical reference for those looking to move the field forward yet again. Divided into two volumes to accommodate this growth, the Embedded Systems Handbook, Second Edition presents a comprehensive view on this area of computer engineering with a currently appropriate emphasis on developments in networking and applications. Those experts directly involved in the creation and evolution of the ideas and technologies presented offer tutorials, research surveys, and technology overviews that explore cutting-edge developments and deployments and identify potential trends. This first self-contained volume of the handbook, Embedded Systems Design and Verification, is divided into three sections. It begins with a brief introduction to embedded systems design and verification. It then provides a comprehensive overview of embedded processors and various aspects of system-on-chip and FPGA, as well as solutions to design challenges. The final section explores power-aware embedded computing, design issues specific to secure embedded systems, and web services for embedded devices. Those interested in taking their work with embedded systems to the network level should complete their study with the second volume: Network Embedded Systems.
