项目摘要

We have already researed the VLSI design system (SYARDS) based on high-level description for 5 years before this project. Besides, This system was evaluated through a connection with the existing VLSI ligic-level synthesis tool. The connection showed possibilities of the high-level synthesis systems like SYARDS.In this project, this system is advanced and generalized in order to implement the system including the design environment, which aims not only processor design but also its application. Moreover, this project is proceeded for the purpose of founding the high-level design technology. Definitely, we deal with problems on the improvement of the specification description language including concurrent processings, its analysis system, and the scheduling and simulator in operation level.As another subject in the project, the design of a double layr parallel network is considered. This research is carried out by Takashi Matsumoto, and important results on a layred architecture for reg … More ularization neuro chips are acquired.The application specification processors which executes the algorithms described in high-level languages (Pascal or C) can automatically be designed using the design system (SYARDS). For 3-year term of project, we strengthen the performance of SYARDS through the optimal design method using the extraction of local parallelism including algorithms, the support technology for bit-width determination, which is needed in dealing with the realistic algorithms for digital signal processing, the introduction of concurrent processing description with C language, and the optimization on the pipeline designs.During the term of project, the concept of co-design is indicated in processor design which considers from both sides of hardware and software. However, this system is originally characterized to design compilers which generate its software as well as hardware. Therefore, this project is also close to the methodology of co-design.In the future, SYARDS will be extended to the direction like this, and the results of this project are considered to have a great deal of significance for the future VLSI design technology.

在此之前，我们已经对基于高层描述的VLSI设计系统（SYARDS）进行了5年的研究。此外，通过与现有的VLSI逻辑级综合工具的连接，对该系统进行了评价。在本项目中，对该系统进行了改进和推广，以实现包括设计环境在内的系统，该系统不仅针对处理器设计，而且针对其应用。同时，本课题的研究也是为了建立高层次的设计技术。当然，我们还讨论了规范描述语言的改进问题，包括并发处理、并发分析系统、操作级的调度和模拟器等，并考虑了双层并行网络的设计。这项研究是由Takashi松本进行的，并在REG的分层架构上取得了重要成果。 ...更多信息利用SYARDS设计系统可以自动设计出执行高级语言（Pascal或C）描述的算法的应用规范处理器。在为期三年的项目中，我们通过采用局部并行性提取的优化设计方法，包括算法、处理数字信号处理实际算法所需的位宽确定支持技术、引入C语言的并发处理描述以及对流水线设计的优化，来增强SYARDS的性能。在处理器设计中引入了协同设计的概念，从硬件和软件两个方面进行考虑。然而，这个系统最初的特点是设计编译器，生成其软件以及硬件。因此，本项目也接近于协同设计的方法论，未来，SYARDS将向这样的方向延伸，本项目的成果被认为对未来的VLSI设计技术有很大的意义。少
