摘　　要：With the improvement of the performance of all components of computers ,Shared Bus, which is the kernelof the traditional computer architecture,has gradually become the bottleneck of the system. This paper presents thelimitations of the Shared Bus. From analyzing the new specifications of the bus ,which are used to solve the bottleneckbrought by shared bus ,it sums up the characteristics of the new technologies from their orientations in the level of thearchitecture. Then by analyzing and comparing the advantages of each new technology ,this paper points out the neworientation of the bus technology.With the improvement of the performance of all components of computers,Shared Bus,which is the kernel of the traditional computer architecture,has gradually become the bottleneck of the system.
