The MVME5500 utilizes the MPC7457 processor running at 1 GHz, which is ideal for

data intensive applications. The MVME5500 provides more than just better processor

performance; it also provides balanced performance from the processor, memory,

dual independent local buses and I/O subsystems.

The powerful Marvell system controller, with support for a 133 MHz host bus and

a 133 MHz SDRAM memory bus, is well matched to the high speed processor. To

match the system I/O to the outstanding processor performance, the MVME5500

provides dual 64-bit, 33/66 MHz PCI buses. Each PCI bus has a PMC site supporting

cards running at 33 or 66 MHz. The Universe II VME interface and PMCspan connec

tor are isolated from the PMC sites on a dedicated 33 MHz PCI bus segment so that

both PMC sites are capable of 66 MHz operation.

The MVME5500 also offers a Gigabit Ethernet interface, a 10/100BaseTX Ethernet

interface and two serial ports. All of this adds up to a set of well-balanced,

high-performance subsystems for unparalleled performance.
