Each PMCspan board supports either two single- n PLX6150 PCI-to-PCI interface wide or one double-wide PMC. By stacking PMCspan boards onto a processor module, bridge a total of four additional single-wide PMCs can be added to Emersons compute engines either today or as future application growth demands. n Support for two single-wide or one double-wide PCI Mezzanine The PMCspan is a standard 6U single-slot VMEbus module that links to its host board Card (PMC) per PMCspan via a PCI expansion connector. It supports both front panel and P2 I/O access for n Stacking capability customer supplied PMCs. n Front-panel and/or P2 I/O n Compliant with PCI local bus specification (revision 2.1) n Injector/ejector handles per VME64 extensions n Compatible with Emersons PowerPlus VME seriesFront page Interior page PMCspan Details Carr IEr B oarDS Pro DuCT oFFEr Ing Emerson offers a full line of PowerPC microprocessor- In order to support the increased PCI bus loading based VME products which can be custom configured associated with additional PMCs, PMCspan uses the for specific applications via on-board PMC slots. The PLX6150. This PCI-to-PCI interface bridge supports a PMCspan expands this capability to further increase 32-bit primary bus interface and a 32-bit secondary customizing alternatives. It is compatible with Emersons bus interface. PMCspan mates directly with the host PowerPlus VME series.

When the maximum of two PMCspan modules are stacked together, the top board does not require a second PCI- to-PCI interface bridge. Software views this secondary module as an extension to the primary PMCspan.
