The Emerson Network Power MVME7100, one of the first VMEbus products with the system-on-chip MPC864xD processor, offers a growth path for VMEbus customers with applications on the previous generation of VME, specifically the MPC74xx processors. The system-on-chip implementation offers power/thermal, reliability, and lifecycle advantages not typically found in alternative architectures.

The Emerson MVME7100 single-board computer (SBC) helps OEMs of industrial, medical, and defense/aerospace VMEbus platforms add performance and features for competitive advantage while still protecting the fundamental investment in VMEbus and related technologies. Customers can keep their VMEbus infrastructure (chassis, backplanes, and other VMEbus and PMC boards) while improving performance and extending the lifecycle. Also, the extended lifecycle of Emerson computing products helps reduce churns in development and support efforts resulting from frequent product changes.

The faster processor and 2eSST VMEbus interface combine to offer significant performance improvement. New cost-effective peripherals can be integrated easily using USB interfaces.

VMEbus 2eSST performance

The 2eSST protocol offers an available VME bus bandwidth of up to 320MB/s, an increase of up to 8x over VME64, while maintaining backward compatibility with VME64 and VME32. The combination of the latest Texas Instruments VMEbus transceivers and the Tundra Tsi148 VMEbus bridge's legacy protocol support allows customers to integrate the MVME7100 series into their existing infrastructure providing backward compatibility and thereby preserving their investment in existing VMEbus boards, backplanes, chassis and software.

Balanced performance

The MVME7100 series provides more than just faster VMEbus transfer rates; it provides balanced performance from the processor, memory subsystem, local busses and I/O subsystems. This coupled with a wealth of I/O interfaces make the MVME7100 series ideal for use as an application-specific compute blade, or an intelligent I/O blade/carrier. The Freescale MPC864xD system-on-chip (SoC) processor, running at speeds up to 1.3 GHz, is well-suited for I/O and data-intensive applications. The integrated SoC design creates an I/O intensive state-of-the-art package that combines dual low power processing cores with on-chip L2 cache and dual integrated DDR2 memory controllers, PCI Express, DMA , Ethernet and local device I/O. The on-chip PCI Express interface and dual DDR2 memory busses are well matched to the processor. To ensure optimal I/O performance, the 8x PCI Express port is connected to a five-port PCI Express switch. Three 4x PCI Express ports are connected to PCI Express-to-PCI-X bridges which provide independent PCI-X busses for the two PMC-X sites and VME bus interface. A 1x PCI Express port is connected to a PCI Express-to-PCI bridge which is connected to the USB chip. The MVME7100 also offers quad Gigabit Ethernet interfaces, USB 2.0, and five (5) RS-232 serial connections. All of this adds up to a set of well-balanced, high-performance subsystems offering unparalleled performance.

Backward compatibility

The MVME7100 series continues the direction of providing a migration path from Emerson's embedded controllers such as the MVME16x, MVME17x, MVME2300/MVME2400, and from Emerson SBCs such as the MVME2600/2700 to a single platform. The MVME7100 series, like the MVME3100, MVME5100, MVME5500, and MVME6100 series, merged the best features of Emerson's embedded controllers and SBCs enabling OEMs to support varying I/O requirements with the same base platform, simplifying part number maintenance, technical expertise requirements, and sparing.

The MVME7100 series offers customers an alternate migration path from the MVME2100, MVME2300, MVME2400, MVME2600, MVME2700, MVME3100, MVME5100, MVME5500 and MVME6100 boards to allow them to take advantage of features such as the integrated MPC864xD SoC processor, DDR2 memory, Gigabit Ethernet, PCI-X, PCI Express, USB, and 2eSST.

PCI expansion

The MVME7100 has an 8x PCI Express connection to support PCI Express expansion carriers such as the Emerson XMCspan.

Transition modules

The MVME7216E transition module provides industrystandard connector access to two 10/100/1000BaseTX ports, and four asynchronous serial ports configured as RS-232 DTE. All of these are via RJ-45 connectors. The MVME7216E RTM is designed to directly connect to the VME backplane in chassis with an 80mm deep rear-transition area.
