3. VMEbus and Core Architecture

VMEbus protocol: Supports 2eSST (Two Edge Source Synchronous Transfer) protocol, with an actual transfer rate of 320MB/s, which is 8 times higher than traditional VMEbus; Simultaneously compatible with legacy protocols such as ANSI/VITA 1-1994 VME64 and VITA 1.1-1997 extensions

Interface chip: using Tundra Tsi148 ™  VMEbus interface chip, paired with Texas Instruments' new VMEbus transceiver, supports operation in standard VMEbus backboards, achieving compatibility with existing VME boards and chassis

Host Bridge: Marvel MV64360 Discovery II Host Bridge, supports 133 MHz host bus and 133 MHz DDR memory bus, and provides dual 133 MHz PCI-X buses to connect VME interface chips and PMC expansion slots respectively, ensuring balanced performance of various subsystems

I/O interface and scalability

1. Basic I/O interface

Ethernet:

Controller: Gigabit Ethernet controller integrated into the host bridge, dual interface design

Speed: 10/100/1000 Mb/s adaptive

Connection: One fixed front end (RJ-45), the other can be front end or switched through the P2 interface (10/100 Mb/s routing to MVME761 RJ-45 in IPMC mode, gigabit routing to P2 in PMC mode)

Asynchronous serial port:

Controller: ST16C554DCQ64 (compatible with 16550)

Quantity: 2, supporting EIA-574 DTE configuration

Speed: up to 38.4 Kbps (EIA-232 standard), 115 Kbps (raw mode)

Connection: one front-end (RJ-45), one for development and debugging (onboard header)

Timer: 4 32-bit programmable real-time timers/counters, 1 watchdog timer (timeout triggers system reset, improves system stability)

2. PMC expansion capability

PMC slot: Dual IEEE P1386.1 compatible with PMC-X slot, supporting the following features:

Bus specifications: 32/64 bit address/data, PCI bus frequency 33/66/100 MHz

Power supply:+3.3V,+5V, ± 12V, compatible with 3.3V/5V signals

Module type: Supports 2 single width or 1 dual width PMC/PrPMC (processor PMC) modules, expandable with additional PowerPC processors to achieve multi processor architecture

PCI Expansion: Provides 32/64 bit, 33/66 MHz PCI expansion connectors (114 pins, compatible with MVME5500 position), supports Motorola PMCSpan and other PCI expansion carriers, further expanding I/O capabilities

3. P2 I/O mode and compatibility module

Dual mode configuration: Supports PMC and IPMC P2 I/O modes through jumper cables, continuing the MVME5100/5500 series design and reducing user migration costs:

PMC mode: compatible with MVME2300/2400, MVME5100/5500, P2 interface provides 64 pins for PMC slot 1 and 46 pins for rear I/O in slot 2

IPMC mode: IPMC761/712 modules need to be installed in PMC slot 1, supporting legacy MVME761/712M I/O modules (limited PMC I/O functionality). At this time, some signals in PMC slot 2 are reserved for expanding SCSI

IPMC module function: IPMC761/712 is an optional PMC module that provides rear I/O support to ensure compatibility with previous generation products such as MVME2600/2700

1 single ended Ultra Wide SCSI port

1 parallel port
