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-onchip (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 (commercial temperature only). 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.
