摘　　要：流处理器体系结构的研究是当今的一个热点,而核级汇编器在流处理器的验证和应用中举足轻重。LT-SP2是一款支持短向量操作的多核流处理器,一条指令能对多个计算单元进行操作。针对LT-SP2的体系结构及系统容错问题,采用了编译程序自动构造方法,提出了冗余备份和校验机制,在此基础上给出了汇编器框图,并实现了支持LT-SP2的汇编器。实验结果证明,所设计的汇编器功能正确,提升了流计算系统的容错性能。Research of stream processor architecture is a hot topic today, and the kernel assembler plays a very important role in the verification and applications of stream processors. LT - SP2 is a multi - core stream processor supporting short vector operations, which means one instruction can operate on mul- tiple computing units. For LT - SP2 system architecture and fault tolerance issues, this paper use the auto- matic compiler construction method and propose a redundancy and check mechanism in this assembler. Based on these, the paper gives the diagram of the assembler and implement it. Experimental results show that the assembly＇ s function entirely meets the needs of the requirement and also improve the fault - tol- erant performance in our stream computing system.
