项目摘要

Towards ultimate integration of complex systems on a single silicon wafer, the main objective of this project is to establish a novel system development paradigm spanning both hardware and software. It is demonstrated that data-driven principle is able to provide common basis for integral design of systems on a chip covering both hardware and software implementations of a given specification. Then it is shown that the software part is most effectively executed on super-pipelined dynamic data-driven processors entirely composed of a self-timed pipeline scheme and distributed over a single chip. The results obtained in the project are summarized as following :1. Super-pipelined ultra-parallel processing mechanism was proposed. In this mechanism, flexible interaction among pipelines can be utilized to implement both algorithmic and non-algorithmic functions such as the genetic functions in GA.Furthermore, during the project, the data-driven multimedia processor DDMP was developed as a core processor in the mechanism. The current version of the DDMP can execute tens billions of signal processing operations per second with power consumption as low as 2 W.2. Multilateral diagrammatic specification scheme was established for natural representation of system function, behavior and data-structures. In the environment, a block diagram like graphical descriptions representing data dependencies among functional blocks are directly transformed into executable data-driven programs preserving the processing structures of target systems. Behavior and data structures which contain additional essential information for the transformation are also represented by diagrammatic forms. e.g. augmented sequence charts, data-structure diagrams, state transition diagrams and decision tables. Further, the transformation scheme was applied to multi-dimensional stream processing such as complex video signal processing and its practicability was demonstrated.

这个项目的主要目标是建立一个跨越硬件和软件的新型系统开发范式，以实现在单个硅片上最终集成复杂系统。它表明，数据驱动的原则是能够提供一个共同的基础，集成设计的系统在一个芯片上，涵盖了硬件和软件实现的一个给定的规格。然后，它示出的软件部分是最有效地执行超流水线的动态数据驱动的处理器完全由一个自定时流水线计划和分布在一个单一的芯片。本项目取得的主要成果如下：1.提出了超流水线的超并行处理机制。在该机制中，流水线之间的灵活交互可以用来实现算法和非算法功能，如遗传算法中的遗传功能。此外，在项目期间，数据驱动的多媒体处理器DSPK被开发为该机制的核心处理器。当前版本的DSPs每秒可以执行数百亿次信号处理操作，功耗低至2 W。建立了多边图形化的规范方案，自然地表示系统的功能、行为和数据结构。在该环境中，一个框图一样的图形描述表示功能块之间的数据依赖关系直接转换成可执行的数据驱动程序，保持目标系统的处理结构。包含用于转换的附加基本信息的行为和数据结构也由图表形式表示。例如扩充序列图、数据结构图、状态转换图和决策表。将该变换方案应用于复杂视频信号处理等多维流处理中，验证了其实用性。
