Book Description
Although programming in memory-restricted environments is never easy, this holds especially true for digital signal processing (DSP). The data-rich, computation-intensive nature of DSP makes memory management a chief and challenging concern for designers. Memory Management for Synthesis of DSP Software focuses on minimizing memory requirements during the synthesis of DSP software from dataflow representations. Dataflow representations are used in many popular DSP design tools, and the methods of this book can be applied in that context, as well as other contexts where dataflow is used. This book systematically reviews research conducted by the authors on memory minimization techniques for compiling synchronous dataflow (SDF) specifications. Beginning with an overview of the foundations of software synthesis techniques from SDF descriptions, it examines aggressive buffer-sharing techniques that take advantage of specific and quantifiable tradeoffs between code size and buffer size to achieve high levels of buffer memory optimization. The authors outline coarse-level strategies using lifetime analysis and dynamic storage allocation (DSA) for efficient buffer sharing as one approach and demonstrate the role of the CBP (consumed-before-produced) parameter at a finer level using a merging framework for buffer sharing. They present two powerful algorithms for combining these sharing techniques and then introduce techniques that are not restricted to the single appearance scheduling space of the other techniques. Extensively illustrated to clarify the mathematical concepts, Memory Management for Synthesis of DSP Software presents a comprehensive survey of state-of-the-art research in DSP software synthesis.

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
The main intention of this book is to give an impression of the state-of-the-art in system-level memory management (data transfer and storage) related issues for complex data-dominated real-time signal and data processing applications. The material is based on research at IMEC in this area in the period 1989- 1997. In order to deal with the stringent timing requirements and the data dominated characteristics of this domain, we have adopted a target architecture style and a systematic methodology to make the exploration and optimization of such systems feasible. Our approach is also very heavily application driven which is illustrated by several realistic demonstrators, partly used as red-thread examples in the book. Moreover, the book addresses only the steps above the traditional high-level synthesis (scheduling and allocation) or compilation (traditional or ILP oriented) tasks. The latter are mainly focussed on scalar or scalar stream operations and data where the internal structure of the complex data types is not exploited, in contrast to the approaches discussed here. The proposed methodologies are largely independent of the level of programmability in the data-path and controller so they are valuable for the realisation of both hardware and software systems. Our target domain consists of signal and data processing systems which deal with large amounts of data.

Book Description
Is your memory hierarchy stopping your microprocessor from performing at the high level it should be? Memory Systems: Cache, DRAM, Disk shows you how to resolve this problem. The book tells you everything you need to know about the logical design and operation, physical design and operation, performance characteristics and resulting design trade-offs, and the energy consumption of modern memory hierarchies. You learn how to to tackle the challenging optimization problems that result from the side-effects that can appear at any point in the entire hierarchy.As a result you will be able to design and emulate the entire memory hierarchy. - Understand all levels of the system hierarchy -Xcache, DRAM, and disk. - Evaluate the system-level effects of all design choices. - Model performance and energy consumption for each component in the memory hierarchy.

Book Description
This volume contains the proceedings of the 7th International Workshop on Software and Compilers for Embedded Systems, SCOPES 2003, held in Vienna, Austria, September 24–26, 2003. Initially, the workshop was referred to as the International Workshop on Code Generation for Embedded Systems. The ?rst workshop took place in 1994 in Schloss Dagstuhl, Germany. From its beg- nings, the intention of the organizers was to create an atmosphere in which the researcherscould participateactively in dynamic discussionsand pro?t from the assembly of international experts in the ?eld. It was at the fourth workshop, in St. Goar, Germany, in 1999, that the spectrum of topics of interest for the workshop was extended, and not only code generation, but also software and compilers for embedded systems, were considered. The change in ?elds of interest led to a change of name, and this is when the present name was used for the ?rst time. Since then, SCOPES has been held again in St. Goar, Germany, in 2001; Berlin, Germany, in 2002; and this year, 2003, in Vienna, Austria. In response to the call for papers, 43 very strong papers from all over the world were submitted. The program committee selected 26 papers for pres- tation at SCOPES 2003. All submitted papers were reviewed by at least three experts in order to ensure the quality of the work presented at the workshop.
