....nodes. Each data node represents either an arithmetic relational logical operation or a read write to a memory or a port. Variations and extensions of CDFG s have been used by many researchers. SOLAR is intended as an intermediate design representation for control dominated mixed HW SW systems [78, 79]. It is based on hierarchical, concurrently executing finite state machines, allowing for the specification of hierarchical communicating FSMs. Tree structures allow for modular specifications. The program state machine (PSM) model integrates a hierarchical, concurrent FSM with programming ....

....can be a mix of hardware and software. In the past few years, a number of institutions started to investigate specific aspects of co design, and currently some prototype methodologies and EDA environments are becoming available within the research community and even commercially( 4] 5] 6] [7], 8] 9] and [10] However, the availability of a general widely applicable co design methodology is still a long way to come, and each approach is usually confined to an application domain or a specific aspect of co design. In our case we considered telecom applications, such as public ....

....It is not clear, however, how structure and structural hierarchy can be described using Petri nets. Communication between parallel threads is only through shared variables. 3.2.2. SOLAR SOLAR is intended as an intermediate design representation for control dominated mixed HW SW systems [IsJe95] JeOB95] It is based on hierarchical, concurrent finite state machines. The principal building block is a StateTable. It allows the specification of hierarchical and communicating FSMs. In addition, three structures have been added to allow modular specifications. The DesignUnit construct is ....

....level of granularity at which partitioning is performed, the degree of automation of the partitioning process, the cost function, and the partitioning algorithm. In [Gupta 93, Ernst 93, Barros 94, Oluko 94] automatic partitioning is performed, while the approaches presented in [Atha 93, Edw 94, Ismail 95] are based on manual partitioning. Partitioning at a fine grained level is performed in [Gupta 93, Ernst 93, Barros 94] In [Atha 93, Kalav 94] partitioning is performed at a coarser granularity. The concrete partitioning criteria also differ from one approach to the other. The basic assumption ....

....not a new term, because almost all digital systems consist of the HW and SW parts. Currently, the research in codesign field is widened into the separate application domains, using very different specification languages and target architectures. There are works pretending to generality like COSMOS [6] and research, concentrating efficiently into narrow applications like Pope Cathedral [8] DSP) Ptolemy [13] datapaths) Still, if we look the typical telecommunication applications, which are belonging into class of CMIST, there are no many competitive approaches, covering all the codesign ....

....have brought new problems konwn as partitionning and communication synthesis. The goal of partitioning is to distribute a system functionality over a set of subsystems where each subsystem is to be executed either in software or in hardware processors [33] The problem of communication synthesis [2], which appears after system level partitioning, is to fix the protocols and interfaces needed by the different susbsystems for the communication. A. Objective When designing distributed embedded systems, communication synthesis becomes essential as different subsystems inevitably need to ....
