Abstract

A special-purpose computer system has been designed to accelerate scanning large databases of DNA and protein sequences (biosequences) for patterns of interest. The system consists of a custom-designed circuit board installed in a host workstation and associated software. The board features a variable number of identical full-custom ASICs. Each biological sequence comparative analysis node. (BioSCAN) ASIC, in turn, features a large one-dimensional systolic array of identical processing elements (PEs). The BioSCAN system scans approximately two million database elements per second. For typical problems this results in a 1000-fold speedup over current workstations.<>

BioSCAN:基于vlsi的生物序列分析系统

一个特殊用途的计算机系统已经被设计用来加速扫描DNA和蛋白质序列(生物序列)的大型数据库，以寻找感兴趣的模式。该系统由安装在主机工作站的定制设计电路板和相关软件组成。该板具有可变数量的相同全定制asic。各生物序列比较分析节点。而(BioSCAN) ASIC则具有相同处理元件(pe)的大型一维收缩阵列。BioSCAN系统每秒扫描大约200万个数据库元素。对于典型的问题，这将导致比当前工作站快1000倍的速度。
