Supercomputing levels of performance in a scalable, single-board computer

The MVME5100 is a high-performance VME processor module featuring the Motorola Computer Group (MCG) PowerPlus II architecture with a choice of

PowerPC

processors—either Motorola’s MPC7400 with AltiVec™ technol-

ogy for algorithmic-intensive computations or the low-power MPC750.

Based on an integrated PCI bridge–memory controller ASIC designed by MCG, PowerPlus II takes memory performance to new levels with 582MB/s memory read bandwidth and 640MB/s burst write bandwidth. Plus, PowerPlus II architecture supports full PCI throughput of 264MB/s without starving the CPU from its memory.

The MVME5100 is designed to m eet the needs of OEMs servicing the mi litary and aerospace, indus trial automatio n, and semicon ductor process equi pment market segments.

MVME5100 P2 I/O

I/O Compatibility

Historically, MCG has offered two tracks in its Po werPC VME portfolio. The first track (which includes the MVME2600/

2700) provides typical single-board computer I/O features including Ethernet, SCSI , multip le serial p orts, a pa rallel p ort, and a single PMC slot. The on-board I/O is routed to P2 and

made available to the user via MCG’s MVME761 or MVME712M transition boards. The second track (which includes the MVME2300/2400) offers limited on-board I/O (Ethernet and a single s eri al p ort b oth vi a the front panel) but provides dual PMC s lots en abling maximum u ser I/ O cus tom ization.

The MVME5100 merges the best features of both tracks enabling the OEM to support varying I/O requirements with the same base platform, simplifying part number maintenance, technical expertise requirements, and sparing.

P2 I/O Modes

The MVME5100 supports two, jumper-configurable P2 I/O modes, PMC mode and IPMC mode.

PMC mode is backward compatible with the MVME2300/ MVME2400. 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 MVME5100 supports legacy MVME761 or MVME712M I/O modules (with limited PMC I/O) when an IPMC761 or IPMC712 PMC card is pop ula ted in PM C Slot 1. In this configuration, PMC Slot 2 contains some signals that are reserved for extended SCSI.

IPMC Modules

The IPMC761 and IPMC712 are optional add-on PMC modules that provide backward compatibility with previous-generation MCG products (such as MVME2600 and MVME2700)

using the MVME761 or MVME712M transition board. IPMC modules provide rear I/O support for

• one single-ended Ultra Wide SCSI port

• one parallel port

• four serial ports (2 or 3 async and 1 or 2 sync/async, depending on module)

With this PMC card configuration, the memory mezzanine, one PMC slot, and the PMCspan are still available, providing support for OEM product customization.

Transition Modules

MVME761

The MVME761 transition module provides industry-standard connector access to the IEEE 1284 parallel port, a 10BaseT or 100BaseT port via an RJ-45 connector, two DB-9 connectors providing acc es s to the asynchronous seri al p orts co nfigured as EIA-574 DTE, and two HD-26 connectors providing access to the sync/async serial ports. These serial ports, labeled as Serial 3 and Serial 4 on the faceplate of the MVME761, are individually user-configurable as EIA-232, EIA-530, V.35, or X.21 DCE or DTE via the installation of Motorola Serial Interface Modules (SIMs).

A P2 adapter provides interface module signals to the MVME761 transition module. The 3-row P2 adapter can be used for 8-bit SCSI. A 5-row P2 adapter supports 16 -bit SCSI and PMC I/O.

MVME712M

The MVME712M transition module provides industry-standard connector ac ce ss to the Ce ntro ni cs® parallel port, a nar-

row SCSI port, and four DB-25 connectors providing access to the asynchronous/synchronous serial ports jumper configurable as EIA-232 DCE or DTE. A P2 adapter provides inter-
