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.

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.
