Overview
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 MVME3100
series into their existing infrastructure providing backward compatibility and thereby preserving their
investment in existing VMEbus boards, backplanes, chassis and software.
BalanCEd PErforManCE
The MVME3100 series provides more than just faster VMEbus transfer rates; it provides balanced perfor
mance from the processor, memory subsystem, localbuses and I/O subsystems.
This coupled with a wealth of I/O interfaces make the MVME3100 series ideal for
use as an application-specific compute blade, or an intelligent I/O blade/carrier.
The Freescale MPC8540 system-on-chip (SoC) processor, running at speeds up
to 833 MHz, 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 a
low power processing core and on-chip L2 cache with integrated controllers for memory,
PCI-X, DMA ,Ethernet and local device I/O.
The on-chip PCI-X bus and a 166 MHz DDR memory bus are well matched to
the processor. To ensure that the MVME3100 series can handle the
320MB/s data rates of 2eSST, the Tsi148 VMEbus interface chip is directly connected to
the integrated PCI-X bus at 66 MHz.
A secondary PCI-X bus has dual PMC-X sites—each site supports PMC or
PMC-X cards supporting PCI bus speeds from 33 to100 MHz.
The MVME3100 also offers dual Gigabit Ethernet interfaces, a 10/100 interface,
USB 2.0. dual Serial ATA ports, and five (5) RS232 serial connections.
All of this adds up to a set of well-balanced subsystems offering unparalleled performance.
