PP877K 3BSE069274R1 depends on the system topology. A large number of multiprocessor nodes can be connected to a large (thousands of processors) system via a SAN (“big bus” model) to support distributed integrated real-time systems for data acquisition, control and data processing applications.The PP877K 3BSE069274R1 packet format includes write xx, read xx, move xx, and lock commands, where xx denotes the allowed data block length (number of data bytes, to the right of the packet header).

The interconnection of PP877K 3BSE069274R1 distributed systems is based on links, bridges, and switching modules (L-modules, B-modules, and S-modules). The cost of communication speed decreases faster than the cost of pins and board space. Traditional communication is based on buses, which limits the number of processors.

Weak interactions between PP877K 3BSE069274R1 processor modules are based on messaging (Ethernet). Intermediate interactions are based on external storage devices used in the cluster (disks, tapes). Strong interactions between processor cores are based on direct reads to distributed memory and are implemented on SCI, which also supports weak interactions between processor modules.Strong interactions for SCI include small packet transactions (packets sent and responded to with echoed separation).
