Beginning with rather small target architectures and single input programs it has developed into a design system for fairly complex time constrained multi process systems and larger heterogeneous target architectures.
So far, the system has mainly been used for design-space exploration where it gives fast response times which are not available in a purely manual design process. Large heterogeneous systems are often composed of several components, such as microprocessors, dedicated hardware, external devices, and memories, interconnected by general or local buses, using ghe variety of communication sysstems. The problems they want to solve can be found in the preface of their book pp.
Due to the problems they want to solve, this project is more concentrated on the formal specification, formal verification and co-simulation. Unlike most of the other tools cosyma, cosmos, etc. They leave the decisions of partitioning and scheduling to the designers, and provide the designers with an environment to quickly evaluate their decisions through formal verification or system co-simulation.
They also put more effort on software synthesis and estimation than th other tools. Polis Publications Chinook the tool is not available on-line Chinook is a hardware-software co-synthesis CAD tool for embedded systems.
It is designed for control dominated, hardwaer-software systems under timing constraints, with a new emphasis on distributed architectures.
Current topics include synthesis of run-time support, communication synthesisand efficient and accurate co-simulation. The two executables are executed, and the captured profiling data is written to a data base as shown in figure 1. The description is also analyzed with a hardware estimator which writes the estimation result to the same database as the profilers.
When the user codesin tool have selected a hardware and software partition, it is written to the database. Generated hardware and software can be co-simulated before and after synthesis, behavioural and RT-level co-simulation.
BEKKA – a heterogenous system level design environment. Your interest may be in simulation or synthesis, for instance.
Hardware/Software Codesign Group
The project intends to develop a codesign methodology and associated tools. Other Papers by Dr. It is closely related to DSP and Telecommunication. The environment CoWare supports efficient heterogeneous co-simulation at different design levels by encapsulating codesjgn most appropriate simulation methods at those levels.
The environment also builds upon existing synthesis and compilation techniques by encapsulating them and supports system design flows by providing design methodology management support The Complete List of Publications of the Project. The hardware and software components are derived from a single SDL-specification. The system is divided into three components: Partitioning, Software generation, Hardware generation.
The partition tool exploits the implicit parallelism of the specified system.
A Framework for Hardware-Software Co-Design of Embedded Systems
It generates software and hardware files. The specification parts dedicated to hardware are then transformed into a VHDL description. This permits the use of a broad range of target FPGA-architectures. A graphical user interface has been developed to specify these systems in a structural and hierarchical way. These systems are stored in a system library. In addition, the graphical user interface is used to define target architectures approah design constraints.
The target architectures are organized in a target architecture library too. The main objective of COOL is heterogeneous implementation. Ptolemy in the acronym is the design tool developed at the Univ. For concurrent and interactive design, we need to provide the following capabilities: Some important research issues in the development are cosimulation, partitioning, and synthesis.
D thesis at UC Berkeley The abstract and table of content of the thesis: This is a tool focussed on real-time systems. It is not for circuit synthesis. The architecture of the system has to be provided by the user. For each chosen architecture SynDEx proposes the best implementation of the algorithm application onto this architecture.
Note this architecture is a “multicomponent architecture” which means the architecture is composed of programmable components processors possibly harxware-software different types and of non-programmable components ASIC, FPGA alltogether connected by communication media possibly of different types.
