To cope with the complex embedded system design, early design space exploration (DSE) is used to make design decisions early in the design phase. For early DSE it is crucial that the running time of the exploration is as small as possible. In this paper, we describe both the porting of our scenario-based DSE to the SPARC T3-4 server and the analysis of its performance behavior.

This work extends an earlier manual design space exploration of our developed Selective Load Value Prediction based superscalar architecture to the L2 unified cache. After that we perform an automatic design space exploration using a special developed software tool by varying several architectural parameters. Our goal is to find optimal configurations in terms of CPI (Cycles per Instruction) an...

Modern signal processing and multimedia embedded systems increasingly have heterogeneous system architectures. In these systems, programmable processors provide flexibility to support multiple applications, while dedicated hardware blocks provide high performance for time-critical application tasks. The heterogeneity of these embedded systems and the varying demands of their growing number of t...

In this paper, we discuss the potential for the use of engineering methods that were originally developed for the design of embedded computer systems, to analyse biological cell systems. For embedded systems as well as for biological cell systems, design is a feature that defines their identity. The assembly of different components in designs of both systems can vary widely. In contrast to the ...

|This paper presents a new polynomial-time algorithm for computing lower bounds on the number of functional units (FUs) of each type required to schedule a data ow graph in a speci ed number of control steps. A formal approach is presented that is guaranteed to nd the tightest possible bounds that can be found by relaxing either the precedence constraints or integrality constraints on the sched...

In this paper an approach is proposed to derive an optimal layout of a Bengali Virtual Keyboard and hence forth seeking the desirable placement of all the keys in that layout within the constraints of space and the key size, thereby seeking to improve the text entry rate for an individual with normal human perception abilities. The approach is partly segmented in identifying the initial layout ...

This paper examines the road train concept as a new alternative in long-distance freight traffic. The design of such a system is a difficult task since many different and conflicting criteria arise depending on the application spectrum, the legal conditions and the preferences of the carrier. Furthermore the evaluation of each decision alternative relies on a time consuming and sophisticated si...

This paper explores the problem of determining the characteristics of the communication links in a computer system as well as determining the best functional partitioning. In particular, we present a communication estimation model and show, by the use of this model, the importance of integrating communication protocol selection with hardware/software partitioning. The communication estimation m...

This paper gives an overview of methods used for Design Space Exploration (DSE) at the systemand micro-architecture levels. The DSE problem is considered to be two orthogonal issues: (I) How could a single design point be evaluated, (II) how could the design space be covered during the exploration process? The latter question arises since an exhaustive exploration of the design space by evaluat...

BSPlab is a simulation environment for studying the interplay between hardware and software in parallel computing. It offers the BSPlib parallel programming library and is based on Bulk Synchronous Parallel (BSP) computing [1], [2]. BSPlab contains a set of high-level performance models of parallel architectures. It can be used as a tool for architectural level design space exploration of BSP c...
