Modeling and model transformations tools are maturing and are being used in larger and more complex projects. The advantage of a modeling environment and its transformation tools cannot be easily exploited by non-expert users as many subtle intricacies determine the efficiency of transformation languages and their tools. We introduce transformation use case examples that highlight such language...

Frequency synchronisation is a vital part of every inner receiver for wireless communication. In this paper we present different implementation alternatives for non data aided frequency estimation of BPSK/QPSK bursts with respect to implementation complexity and communications performance. Results with regard to different quantization levels, varying burstlengths, frequency offsets and modulati...

We present an automated temporal partitioning and design space exploration methodology that temporally partitions behavior speci cations. We propose block-processing in the temporal partitioning framework for reducing the recon guration overhead for partitioned designs. Block-processing is a technique used traditionally in the area of parallel compilers, for increasing the computation speed by ...

This session deals with modeling and simulating extra-functional system properties. The first paper presents a framework to accurately model the power and timing of hardware models without requiring a full micro-architectural simulation of the hardware module to extract signal transitions. The second paper presents a method to extend Design Space Exploration (DSE) of systems with Out-of-Order e...

The exploration problem has been extensively studied in unsafe networks containing malicious hosts of a highly harmful nature, called black holes, which completely destroy mobile agents that visit them. In a recent work, Královič and Miklík [SIROCCO 2010, LNCS 6058, pp. 157–167] considered various types of malicious host behavior in the context of the Periodic Data Retrieval problem in asynchro...

In this paper we examine the multi-criteria optimization involved in scheduling for data path synthesis (DPS). We present a method to find non-dominated schedules using a combination of restricted search and heuristic scheduling techniques. Our method supports design with architectural constraints such as the total number of functional units, buses, etc. The schedules produced have been taken t...

SystemCoDesigner is a software tool for automatic design space exploration at the electronic system level and automatic platform-based prototyping of hardware/software systems using SystemC.

As microprocessor-based systems grow in complexity, and the processor-memory speed gap widens further, more emphasis needs to be placed on early design space exploration in order to produce the highest performance systems with minimal schedule impact. We discuss the critical issues associated with architectural evaluation of complex microprocessor-based systems, and present a methodology for th...

In this paper, a methodology for estimating area, energy consumption and execution time of an application executed on a specified processor is proposed. In addition, a design exploration process to find suitable processor architectures for a specific application is proposed. Cost and performance estimation is an important part of the exploration process. The actual cost estimation is based on p...

In this paper, we propose a novel performance estimation method of software function blocks considering the effect of architecture variation, compiler optimization, and data dependent behavior. In the proposed design space exploration framework, a system behavior is specified as a composition of function blocks and the execution order of the blocks is known a priori. We run the entire applicati...
