FM9925a-E機器人模塊還提供堆疊PMC的功能基板上的承載板用于額外擴展。MVME2603/2604支持一個PMC插槽。打開四個64針連接器基板（J11、J12、J13和J14）與32位IEEE P1386.1接口PMC兼容夾層，可添加任何所需功能。PCI夾層卡插槽具有以下特點：PMC載體板連接器（J5）是114針Mictor連接器。請參閱第4章連接器引腳分配，了解
PMC連接器。有關(guān)詳細的編程信息，請參閱《MVME2603/2604程序員參考》中的PCI總線描述附錄D相關(guān)文件中列出的指南，并提供給用戶您打算使用的PMC模塊的文檔。VMEbus接口VMEbus接口使用CA91C042 Universe實現(xiàn)ASIC。Universe芯片將32/64位PCI本地總線連接到VMEbus。Universe ASIC提供：? PCI總線到VMEbus接口

PCI Mezzanine Interface
A key feature of the MVME2603/2604 family is the PCI (Peripheral
Component Interconnect) bus. In addition to the on-board local bus
devices (SCSI, Ethernet, graphics, etc.), the PCI bus supports an industrystandard mezzanine interface, IEEE P1386.1 PMC (PCI Mezzanine Card).
PMC modules offer a variety of possibilities for I/O expansion through
FDDI (Fiber Distributed Data Interface), ATM (Asynchronous Transfer
Mode), graphics, Ethernet, or SCSI ports. The base board supports PMC
front panel and rear P2 I/O. There is also provision for stacking a PMC
carrier board on the base board for additional expansion.
The MVME2603/2604 supports one PMC slot. Four 64-pin connectors on
the base board (J11, J12, J13, and J14) interface with 32-bit IEEE P1386.1
PMC-compatible mezzanines to add any desirable function. The PCI
Mezzanine Card slot has the following characteristics:
The PMC carrier board connector (J5) is a 114-pin Mictor connector.
Refer to Chapter 4, Connector Pin Assignments for the pin assignments of
the PMC connectors. For detailed programming information, refer to the
PCI bus descriptions in the MVME2603/2604 Programmer’s Reference
Guide, listed in Appendix D, Related Documentation, and to the user
documentation for the PMC modules you intend to use.VMEbus Interface
The VMEbus interface is implemented with the CA91C042 Universe
ASIC. The Universe chip interfaces the 32/64-bit PCI local bus to the
VMEbus.
The Universe ASIC provides:
? The PCI-bus-to-VMEbus interface
? The VMEbus-to-PCI-bus interface
? The DMA controller functions of the local VMEbus
The Universe chip includes Universe Control and Status Registers
(UCSRs) for interprocessor communications. It can provide the VMEbus
system controller functions as well. For detailed programming
information, refer to the Universe User’s Manual and to the discussions in
the MVME2603/2604 Programmer's Reference Guide, listed in Appendix
D, Related Documentation.
