Overview

VMEbus 2eSST Performance

The 2eSST protocol has existed for some time (the draft standard for trial use was published in 1999 and released as an ANSI standard in 2003), but until now, 2eSST boards would not work in a standard VMEbus backplane because the existing VMEbus transceivers could not support the required VMEbus 2eSST signaling speeds. Texas Instruments developed new VMEbus transceivers that support the VMEbus signal switching speeds required by the 2eSST protocol. The combination of the new Texas Instruments VMEbus transceivers and the Tsi148 VMEbus legacy protocol support allows customers to integrate the MVME6100 series into their existing infrastructure providing backward compatibility and thereby preserving their investment in existing VMEbus boards, backplanes, chassis and software.

Balanced Performance

The MVME6100 series provides more than just faster VMEbus transfer rates; it provides balanced performance from the processor, memory subsystem, local buses and I/O subsystems. The processor, running at speeds of 1.267 GHz, is ideal for data-intensive applications. The state-of-the-art host bridge, with support for a 133 MHz host bus and a 133 MHz DDR memory bus, is well matched to the processor. To ensure that the MVME6100 series can handle the 320MB/s data rates of 2eSST, the Tsi148 VMEbus interface chip is connected to one of the 133 MHz PCI-X buses on the host bridge. The second PCI-X bus has dual PMC-X sites—each site supports PMC or PMC-X cards supporting PCI bus speeds from 33 to 100 MHz. The MVME6100 also offers dual Gigabit Ethernet interfaces. All of this adds up to a set of well-balanced, high-performance subsystems for unparalleled performance.

Application Benefits

Defense and Aerospace

In the defense and aerospace market segment, the MVME6100 series is well suited for command and control applications that utilize commercial grade products such as naval sheltered systems, stationary ground systems, and reconnaissance aircraft systems. The MVME6100 series helps to provide more performance for these applications than previous VME solutions have been able to supply by using the 1.267 GHz processor. This combined with dual PCI-X buses capable of 100 MHz speed for PMC modules and an 8x increase in the VME bandwidth eliminates many of the bottlenecks faced by command and control solutions today. These applications can now take advantage of the latest PowerPC processors in a dense computing configuration without the difficulties of trying to cool multiprocessor boards and managing I/O and VME bottlenecks. With the addition of Emerson’s processor PMCs (PrPMCs), additional PowerPC architecturecompatible processors can be added for a multiprocessor solution without sacrificing any of the MVME6100 series benefits.

Industrial Automation

Industrial Automation The MVME6100 is also ideally suited for semiconductor process equipment (SPE), automated test equipment (ATE) and a variety of other high-end industrial automation applications because of its increased bus bandwidth and faster processing speeds. The backwards compatibility of the MVME6100 series with existing VME products helps to provide OEMs a way to extend the life and capability of their current designs without sacrificing existing key hardware and software investments. The DSP-like AltiVec technology, which is incorporated into the processor, allows the MVME6100 series to be used for an assortment of vector processing applications. And with two PMC sites, the MVME6100 series can be customized.

Medical Imaging

Medical imaging applications such as Nuclear Medicine (NM), Positron Emission Tomography (PET), Magnetic Resonance Imaging (MRI), X-Ray and Computed Tomography (CT) that entail intensive image processing, manipulation and algorithmintensive computations can benefit from the 2eSST protocol’s 8x increase in VMEbus transfer rates. With the ability of the MVME6100 series to work with existing VMEbus backplanes and boards, OEMs can increase their overall system performance while protecting their software and hardware investments. The performance of the MVME6100 series also helps OEMs to reduce the overall number of embedded cards required in a medical imaging application so that space issues become less of a factor.

P2 I/O Modes

The MVME6100 series supports two, jumper-configurable P2 I/O modes: the PMC mode and IPMC mode. PMC mode is backwards compatible with the MVME2300/MVME2400 and MVME5100/MVME5500 in PMC mode. In PMC mode, 64 pins from PMC slot 1 and 46 pins from PMC slot 2 are available on P2 for PMC rear I/O. In IPMC mode, the MVME6100 series supports legacy MVME761 or MVME712M I/O modules (with limited PMC I/O) when an IPMC761 or IPMC712 PMC card is populated in PMC slot 1. In this configuration, PMC slot 2 contains some signals that are reserved for extended SCSI
