Rapid prototyping of complex systems embedded in even more complex environments raise the need of a multi-level design approach. Our example is taken from mechatronic design of the automotive industry and illustrate the rapid prototyping procedure of real-time critical control laws. Our approach is based on an object oriented structuring allowing not only(More)
This paper describes an environment for the rapid analysis, synthesis and optimization of embedded systems. Since the implementation of these systems is rather complicated, we propose a methodology which automates the entire design flow. Flexibility is achieved by allowing manual intervention which is realized via a modular implementation of algorithms(More)
HW/SW codesign is becoming an increasingly more interesting research field because most practical systems consist of both HW and SW. In this paper we explore a bottom up HW/SW codesign strategy to investigate trade-offs in time behavior and area. A comparison of hardware and software implementations of low level modules is given. A first prototype(More)
IP based design comprises two main steps. First, a suitable IP has to be found. Second, the IP has to undergo further processing before it can be included in existing designs. Since IP providers use different formats and design tools require different parts of the IP for their services it is hard to find an IP format that satisfies and is exchangeable(More)
In this paper, the feasibility and necessity of a new concept for radio standard spanning communication in mobile Ad Hoc networks (MANET) has been analysed. Past research approaches limited their solutions to the usage in a homogeneous topology on basis of a unique radio standard. The proposed concept offers the possibility to connect standardised radio(More)
Verification and test issues raise the need for rapid prototyping of complex systems and especially hardware/software-systems. We tackle this problem by integration of hardware/software-codesign and prototyping. First we define the concept of the entire system architecture. This concept directs the hardware/softwarepartitioning process. Our prototyping(More)
High level design decisions as HW/SW-partitioning and instrumenting of building blocks can be supported efficiently by detailed analysis of dynamic instruction usage. In many cases the instruction usage is specific to the application domain in view. We present a very fast analysis approach based on high level system models. Complex application(More)
