....to complement performance or add functionality not achievable by pure program implementations. Recent advances in hardware synthesis and the proliferation of advanced and inexpensive microprocessors and processor cores have lead to the emergence of research interests in hardware software co design [4, 5,6,7,8,9,10]. Synthesis of systems containing re programmable components can be thought of as extension of highlevel synthesis techniques to systems containing generalized resources . However, due to differences in the computation model of the operations implemented in re programmable and ....

....processors. In this paper we formulate a Mixed Integer Linear Program (MILP) that allows to determine a mapping optimizing a trade off function between execution time, processor and communication costs. It is desirable to have a mapping approach that optimizes a function depending on such factors [14]. For some tasks it is obvious which task has to be implemented in hardware and which one in software. For example, a high speed packet manipulation should be implemented in hardware while recursive searching is always implemented in software. However, there are tasks, which may be implemented ....

Often software generation for a given target architecture requires linearization ....

....or concurrent implementations must be taken into account. Others (e.g. Aco92] define it as the choice of the best processor bus memory architecture that suits a given software specification. We will use the term in a different sense (common, e.g. to [SB91] GJM92c, GJM92b, GJM92a] WWD92] meaning the design of a special purpose system composed of a few Application Specific Integrated Circuits cooperating with software procedures on general purpose processors. This restricted definition is still too wide to allow a useful formalization of generally applicable automated ....
