....Framework This problem is similar to several other important research questions; and, while different in some respects, may find useful insight in such approaches. The hardware software codesign field views system synthesis as a search for the minimal hardware that fulfills a fixed utility[Kalavade93]. We are attempting to find the maximum utility that can operate on fixed hardware. Reconfigurable computing uses special hardware, typically a Field Programmable Gate Array (FPGA) and dynamically modifies the operation of that hardware to increase performance. We reconfigure an entire ....

....an integrated hardware software work breakdown structure of the candidate architecture. Using the work breakdown structure, PRICE returned the cost to RDD 100, where it was assigned to the corresponding architecture blocks. Other synthesis approaches either factor in only hardware costs, 6] [9], or only software costs, 10] during the system design process. In [11] both hardware and software costs are determined from libraries consisting of functional units with their corresponding performance, and dollar costs. The majority of codesign and synthesis approaches that address dollar ....

....or software. Similarly, a number of commercial and research tools use dataflow to specify signal processing systems that can be implemented either way [32] 35] 41] It has also been shown that a single dataflow specification can be partitioned for combined hardware and software implementation [21][22]. 2. Multi paradigm design In this paper, we will focus on the interaction between dataflow models, with their partially ordered events, and discrete event models, with their notion of time defining a (mostly) total order of events. A variety of interaction semantics are explored, and an ....

....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 ....

Thomas, Adams, and Schmit s cosimulation scheme [3] is similar to [2] but their technique is based on synchronized handshake with no processor model. Cosimulation techniques of Poseidon [4] and Ptolemy [5] need pin level model of processors. Their approaches are most accurate but take much more simulation time. In this paper, we present a hardware software cosimulation environment for heterogeneous systems. To be an efficient system verification environment for the rapid prototyping of a ....

....of view of the time constraints and cost, the generation of executable code, the synthesis of hardware, and the production of the interface between hardware and software, i.e cosynthesis. A lot of work has been done, the purpose of which was to define a well structured methodology for codesign [7] [11] [19] An important point was generally the description of both hardware and software using the same language, like for instance Vhdl enhanced with mechanisms for calling C functions [14] or high level languages like C, C or Fortran extended with facilities for the description of hardware ....

....a larger range of real time systems using Signal and second, the integration of Signal and other languages like Alpha in a co design framework. The term co design has been used to denote the specification, validation and implementation of systems consisting of both hardware and software components [22, 23]. Since Signal and Alpha have complementary properties, they can be used in a hw sw codesign framework in which the Alpha language would specify and synthesize the hardware parts of a system and Signal will describe the software. The Signal Alpha cooperation will thus respond to some of the ....

Cosimulation techniques of Poseidon [7] and Ptolemy [8] need pin level model of processors. Their approaches are most accurate but take much more simulation time. Although above existing approaches vary in model availability, accuracy, and time, they all did not take into account interface model explicitly or efficiently. In this paper, we present a ....

Since they have excessive communication overhead due to the interface, real degree of simulation acceleration is much smaller than expected. l Buck, et al. [21,9] developed Ptolemy design environment, a unified framework that allows the hardware and software components to be integrated from the specification through the synthesis, simulation, and evaluation phases. It uses an objectoriented software technology to model each subsystem and has mechanisms to ....

The interface model is based on inter process communication (IPC) routines connecting the two processes through Unix socket [10] on a single Sparc CPU.

Stringent processing and reliability requirements imposed on these complex systems as well as the need for low cost and little time to market make a revision of the traditional design methods necessary. A number of authors [2,3,7,8,13] have been suggesting various approaches to address these issues using hardware software codesign. We have been proposing a high level system design approach called model based codesign that relies heavily on simulation modeling techniques to explore the feasibility of virtual prototypes [1,12] ....
