General Description
The MVME2603/2604 is a VME module single board computer equipped
with a PowerPC Series microprocessor. The MVME2603 is equipped with
a PowerPC 603 microprocessor; the MVME2604 has a PowerPC 604.
256KB L2 cache (level 2 secondary cache memory) is available as an
option on all versions.
As shown in the
Features
section, The MVME2603/2604 offers many
standard features desirable in a computer system—such as synchronous
and asynchronous serial ports, parallel port, boot ROM and DRAM, SCSI,
Ethernet, support for an external disk drive, and keyboard and mouse
support—in a single-slot VME package. Its flexible mezzanine
architecture allows relatively easy upgrades in memory and functionality.
A key feature of the MVME2603/2604 family is the PCI (Peripheral
Component Interconnect) bus. In addition to the on-board local bus
peripherals, the PCI bus supports an industry-standard 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 I/O. There is also provision for additional expansion via a PMC
carrier board.
