CTaiJi——新的粗粒度可配置计算结构研究

Coarse-grained Reconfigurable Computing Architecture—CTaiJi

首先阐述了粗粒度可配置计算结构在进行数据处理时的特点。依据此特点,提出了CTaiJi粗粒度可配置结构,详细说明了结构中各个组成部分。在系统结构中,将环形结构与网格结构相结合,PEZ(处理单元组合)非常适合处理循环、条件语句。能够将循环、条件及简单算术运算集中于同一PEZ中实现,利于系统实现实时配置和提高PE(处理单元)利用率。介绍了常用的数字信号处理算法在此粗粒度可配置结构上的映射。

Depended upon multi-parallel execution models, the coarse-grained reconfigurable architecture- an approaches to deal with these limitations- comes forth. The data-processing characteristic of the reconfigurable architecture is pointed out. A new coarse-grained reconfigurable architecture-CtaiJi （china TaiJi） is conceived. The Ctaiji is a reconfigurable device with data-paths and functions of processing-elements （PE） that can be configured to implement the DSP algorithms efficiently. Most parts of the CtaiJi architecture is introduced in this paper. Finally, several digital signal processing algorithms used ot discuss and map onto the coarse-grained reconfigurable architecture.
