    A methodology aimed at prototyping real-time image processing VLSI systems is presented. The prototyping methodology includes the emulation of the application in its target environment (i.e., in real time and on real-world scenes) and the automatic derivation of a VLSI chip-set implementing the application. Our methodology is based on a custom emulator called the Data-Flow Functional Computer (DFF... View full abstract»

    We present a system emulator for rapid prototyping of small embedded HW/SW-systems with hard timing constraints generated by a HW/SW cosynthesis system. It consists of a standard core processor and an application specific coprocessor, which is emulated by XILINX FPGAs. A byte slice architecture allows to emulate rather complex coprocessors. The system emulator supports the prototyping, debugging a... View full abstract»

    Microsystems technology is a rapidly growing field, but engineering tools for microsystems do not appear as fast as the technology is moving. In this paper, we show that methods and tools developed for the information processing units in macro systems, e.g. mechatronic systems, can be reused in microsystems development. The methods and tools we present cover the requirements analysis phase of the ... View full abstract»

    GRAPE-II (Graphical Rapid Prototyping Environment-II) is a hardware-software codesign environment for the real-time functional emulation of synchronous DSP systems. It allows one to specify the application's data dependency graph in a target-machine-independent way. After specifying the heterogeneous target machine's architecture, it estimates the resources needed by each application subtask. Base... View full abstract»

    This paper discusses a novel transformation-based design methodology and its use in the design of complex programmable VLSI systems. During the life-cycle of a complex system, the optimal trade-off between partially implementing in hardware or software is changing. This is due to varying system requirements (short time-to-market, low-cost, low-power, etc.) and improving the device technology. The ... View full abstract»

    An approach is presented that permits the configuration of application specific hardware, with arbitrary hardware redundancy, to match the signal flow graph of arbitrary applications. The hardware is mapped to the signal flow graph of an application. An inventory of heterogeneous processors, specialized to perform a predefined set of functions, enables rapid prototyping of systems with arbitrary t... View full abstract»

    The teaching of digital design requires a design platform which presents a coherent design methodology to the students. Yet we found ourselves with different tools and hardware subsystems, each having its own idea about what digital design was about. Here we record our effort to forge a single design platform for beginning designers from three separate software subsystems and two hardware subsyste... View full abstract»

    The requirements specification phase of the software lifecycle has been recognized as being critical for the development of large complex software systems. Rapid prototyping techniques can be applied to develop executable models to help eliminate the ambiguity, inconsistency and incompleteness in requirements specifications, which are often the source of errors and inefficiencies in subsequent lif...

    Rapid prototyping is well suited to address the signal processing design tasks encountered an research applications. The applications differ from defence or industrial applications in that the signal processing requirements are either evolving or poorly understood. In the field of underwater acoustic (UWA) communications, practical solutions, and thus their implementations, are still maturing. San... View full abstract»

    An algorithm for the hardware/software partitioning problem is presented. In data flow systems, task scheduling modifies global characteristics and allows different implementation solutions. Our algorithm is based on assignment and scheduling algorithms which are well known in high-level synthesis. At each iteration, one task is scheduled if it involves the weakest constraints on the other tasks. ... View full abstract»

    The extended partitioning problem is the joint problem of mapping nodes in a precedence graph to hardware or software, and within each mapping, selecting an appropriate implementation for each node. The end-goal is to minimize the hardware area, subject to architectural and performance constraints. This is an NP-complete problem; we present an efficient heuristic called MIBS to solve it. The MIBS ... View full abstract»

    Prototyping has been used to develop electronic systems for a long time. In this work a new prototyping approach, that we named VHDL Virtual Prototyping, is introduced. The new approach introduces VHDL models as the hardware part of the system prototype. The software components of the system are then executed and debugged on top of the hardware models of the system.

    Since software prototypes of DSP applications are most efficient when their code and data space requirements can be accommodated entirely within the on-chip memory of the target processor it is crucial to employ efficient memory-minimizing compilation techniques in a DSP software prototyping system. In this paper, we introduce two techniques for the combined minimization of code and data when comp... View full abstract»
