项目摘要

Plastic cell architecture (PCA) is one of dynamically reconfigurable devices proposed by Prof. Oguri, one of the investigators. PCA has uniform fine grained structure with processing parts and memory parts and it is expected to be a breakthrough for the Von Neumann bottleneck between CPU-memories. This project aims to develop methodologies for circuit design and to survey applicable fields.1) Development of Asynchronous Circuit Design Methodology on PCA・ Prototyping process using software with hardware simulator was introduced to improve efficiency in asynchronous circuit design.・ A library set including small size modules that are guaranteed to have no errors are established. These modules are connected by communicating paths and form larger scale asynchronous circuits. Based on the library, a lot of applications have been developed.・ A simulation environment and a design methodology based on bit-serial processing were proposed.・ A GUI layout tool and a verification tool were developed for improving design environment.2) Design Languages for PCA・ Semi-automatic conversion flow from HDL (SFL) to asynchronous circuits was proposed in order to utilize the conventional synchronous design resources in the past.・ Hierarchical CDFGs and a dividing algorithm for the CDFG were proposed to create synthesizable STG from higher level specifications.3) Device Structure for High Package Density・LUT (look-up table) circuits for were investigated and two ways for high-speed operation were proposed.4) Applications on PCA・ In order to use reconfigurability, that is a feature of PCA, a vector processor, instruction-level parallel processor, serial multiplier. FIR filters were investigated.・ Hardware implementation of artificial neural network was applied to PCA. Wire connection problem was solved by the use of dynamical wiring of PCA.

塑料单元结构（Plastic Cell Architecture，PCA）是研究者之一小栗旬教授提出的一种动态可重构器件。PCA具有处理部分和存储部分统一的细粒度结构，有望突破CPU-存储器之间的冯·诺依曼瓶颈。1）基于PCA的异步电路设计方法学的开发·为了提高异步电路设计的效率，引入了使用软件和硬件模拟器的原型化过程。·建立包括保证没有错误的小尺寸模块的库集合。这些模块通过通信路径连接，形成较大规模的异步电路。基于该库，开发了许多应用程序。·提出了一种基于位串行处理的仿真环境和设计方法。2）PCA的设计语言。为了充分利用以往同步设计资源，提出了从HDL（SFL）到异步电路的半自动转换流程。3）研究了高封装密度的器件结构·查找表（LUT）电路，提出了两种实现高速运算的方法。4）在PCA上的应用·为了利用PCA的可重构性，设计了矢量处理器、并行级处理器、串行乘法器。研究了FIR滤波器。·将人工神经网络的硬件实现应用于PCA。利用PCA的动态布线解决了接线问题。
