WebMultiport memory Crossbar switch Multistage switching network Hypercube system Time Shared Common bus A common-bus multiprocessor system consists of a number of processors connected through a common path to a memory unit. A time-shared common bus for five processors is shown in figure below. WebThe crossbar operates at 120 MHz (8.33 nanoseconds). The path width to the agent and memory controller chips is 64-bits. Thus the rated bandwidth of a crossbar port is 960 MBytes/s, in each direction. The crossbar is non-blocking so that all ports can be operating at full bandwidth as long as their target ports are unique.
