| 主要研究成果包括共享存储系统结构的基础理论,
共享虚拟存储系统, 以及处理器系统结构设计等方面。 在共享存储系统结构方面, 建立了一个共享存储系统的执行正确性模型,
讨论了正确执行的访存次序条件, 提出了一个在顺序一致的共享存储系统中实现乱序执行的方案, 并对该方案进行了模拟。 建立了一个描述存储一致性模型的数学模型,
给出了并行程序及系统结构是否满足某种存储一致性的标准。提出了一个基于锁的高速缓存一致性协议, 该协议比传统的目录协议具有更好的性能和可伸缩性。
在共享虚拟存储系统方面, 实现了一个虚拟共享存储系统JIAJIA, 该系统实现锁的高速缓存一致性协议，并在国际上的同类系统中首次实现了把多台机器的内存空间组织成更大的共享空间。目前，该系统已被二十多个国家和地区的一百多个科研单位使用。在JIAJIA系统的研制过程中，提出了若干虚拟共享存储系统的优化策略，如单写的识别、数据自动迁移、写向量、基于SMP机群系统的优化等。目前基于JIAJIA的工作已经在国内外刊物和会议上发表论文几十篇。
在先进处理器系统结构方面, 目前已经完成先进处理器的系统结构设计、软件模拟、及逻辑设计。该处理器系统结构先进，采用了目前国际上处理器设计的大量先进技术如指令流水线、指令动态调度、猜测执行、高速缓存、精确中断、多发射等，并在某些关键技术如动态流水线的寄存器重命名等方面有所创新。此外，该处理器可伸缩性好，可以根据不同的要求进行不同的配置而不用改变系统结构，适用于从嵌入式应用到高性能计算机等不同领域。
