Abstract

In this paper, aiming toward a compact high-throughput reconfigurable architecture, we propose the reconfigurable processor DS-HIE. In order to achieve the characteristics of compactness and high-throughput, the DS-HIE architecture executes operations following a bit-serial computation scheme and adopts a Benes network as its routing resource. Implementing bit-serial computation brings the advantage of small chip area and high throughput to the DS-HIE architecture, and the Benes network ensures the high availability of the routing paths within a compact chip area. In this paper, we evaluated its transistor count and performance, compared with the RISC processor MeP. From this evaluation, the DS-HIE processor required 9.2 times the transistor count of the MeP processor, it achieved 13 to 33 times higher performance as compared with the MeP processor.
基于位串行计算的紧凑高吞吐量可重构体系结构评价
本文针对一个紧凑的高吞吐量可重构架构,提出了可重构处理器DS-HIE。为了实现紧凑和高吞吐量的特点,DS-HIE架构采用位串行计算方案执行操作,并采用Benes网络作为路由资源。实现位串行计算为DS-HIE架构带来了芯片面积小、吞吐量高的优势,而Benes网络保证了紧凑芯片面积内路由路径的高可用性。在本文中,我们对其晶体管数量和性能进行了评估,并与RISC处理器MeP进行了比较。从这个评估来看,DS-HIE处理器需要的晶体管数量是MeP处理器的9.2倍,它的性能比MeP处理器高13到33倍。
