.... design paradigm which first manifested itself in the form of system decomposition into modules, information hiding [13] and program families [14] This success can be attributed to the natural concept of perceiving a hardware component as an individual class with characteristics and operations [10]. In fact, we believe that the decomposition of a system into objects is better defined and more explicit in hardware than in software because a hardware system can be easily decomposed into components, while conventional software programs are often structured using procedures that are more ....

In the design of a RTES, decisions made at the architectural design phase greatly affect the final implementation and performance of the system [1,4,6]. A system designer has to overcome a number of challenges at this phase. For instance, the details of a system specification are not fully specified. Even if it is fully specified, it is often the case that the specification will be altered from the time of the first formulation of the system ....

....of polymorphism relies on pointer manipulation. We describe how pointers have been identified as useful, the capability of their usage, and describe how to solve some of the associated debugging problems. Introduction Object oriented methodology for hardware design have been proposed in [4, 10] and [11] to increase the level of abstraction to address the growing complexity of implementations. Class libraries as an extension to the C language have been proposed recently to address the increasing complexity of system design [7, 1] Such techniques and languages were applied in ....

....POSM has been validated using a high level Petri net model called MOBnets. Keywords: multiprocessor systems, object oriented design, parallel synthesis 1. Introduction Object oriented technology had been successfully applied to the system level synthesis of multiprocessor systems [6] [8], 2] The efficiency of the methodologies can be considerably enhanced if the synthesis of components can be parallelized. Parallel computer aided design had been used only in logic and high level syntheses [1] We now present a method for parallelizing object oriented system level synthesis. ....

....the design methodology. Rather than searching the entire design space exhaustively, several techniques have been proposed in the past to partially explore the region that most likely contains the optimal design solution. The techniques include fuzzy logic [9] learning [10] object oriented design [11], object oriented language [12] specification reuse [13] distributed exploration [14] and formal approaches [15] Though the proposed techniques help to increase synthesis efficiency, yet they do not guarantee optimal solutions. With the increasing wide spread use of objectoriented ....

High Level Constructs: Provide high level programming constructions for effective and efficient compositions of element types. The object oriented language C is well suited to model the structure of architectures [10]. A parser is used to check whether the architecture instances that were modeled are feasible. 5.1. Object Oriented Principles Objects are instantiated from class descriptions. In the definition of a class, a strong separation is made between the interface of an object method and the ....

The properties of the object oriented paradigm, such as modularity, extensibility, reusability and reduced code, allow the automatic code generation of a software prototype to test the designed microarchitecture. In fact, the objects representing hardware components constitute a library of ....

....little and ad hoc design reuse. Many SOCs using processor cores are not merely ASICs, but platforms for running embedded software, a large fraction of the value is in the software. But, we still have fragmented hardware and software design flows, despite many notable efforts made to close the gap [3, 5]. We believe that there is a need to push the design process and notation to a higher level of abstraction to encapsulate these problems, or take different views on them. Higher abstraction implies automation, adherence to rules , and well defined interfaces. Doing this, we can structure the ....

....we will be able to better manage complexity and reach an IP abstraction [4] that will add to the composability of SOC designs. Mirroring their growth in the design of complex software systems, object oriented methods have been adapted to microelectronic IC and system design. See for instance [5, 6]. These techniques were applied in successful chip designs in [7, 8] This work builds upon these earlier efforts by focusing on the design process, and explores changes needed to enhance the designers productivity. We will go back to the specification level (of the design methodology) and focus ....

....of extremely flexible generic components. For the same reason, Bl ml [5] has developed a workbench for the generation of flexible quality VHDL cells. Other techniques consist of providing VHDL with object oriented extensions [6] Another solution is to organize a hierarchy of reusable C classes [7]. At different levels of complexity (e.g: gates, registers, ALU, memories, processors) each of these classes is able to handle all aspects of a component such as parameters, functionality, behavior. Other works have focused on developing efficient tools managing the reusability of designs for ....

....Object Orientation A number of the proposals for extensions to VHDL [5, 6, 11, 45] suggest that object oriented classes are the most appropriate mechanism for abstract system level modeling. While it is true that classes can be used to model hardware systems, as demonstrated by Kumar et al. [34], the class based approach gives rise to significant problems. Indeed, Kumar et al. state that they use C to demonstrate the usefulness of object oriented techniques, not to provide arguments for or against its use in hardware modeling and design. It is unfortunate that the term message ....

....step wise refinement approach. Early versions will use crude high level abstractions that might be replaced by more detailed and realistic models. It is expected that C will be a suitable implementation language. Even though C has been used in modeling computer architectures and hardware [Kum94] it will be a sub goal to investigate the possibility of integrating hardware description languages such as VHDL and Verilog in the simulator. Such languages may be used for simulating alternative implementations of performance critical parts (e.g. synchronization) of the investigated ....
