The Implementation and Analysis of Smith-Waterman Algorithm on Systolic Array
Author(s): 
Pages: 12-20
Year: Issue:  1
Journal: CHINESE JOURNAL OF COMPUTERS

Keyword:  脉动式阵列共享寄存器序列比对Smith-Waterman算法;
Abstract: Smith-Waterman算法是一种经典的序列比对算法,在双序列比对的情况下具有比较好的性能,但是在大规模的序列比对时,其性能并不能令人满意.脉动式阵列和Smith-Waterman算法有比较好的吻合性.该文通过在龙芯1号处理器上附加一个脉动式阵列的协处理器,构建了硬件模型.通过模拟器的验证,附加了协处理器的龙芯1号的性能与没有附加协处理器时的性能之比接近于线性.该文最后根据硬件模型和模拟器的性能数据,具体分析了系统各个方面对性能提高的影响.
