General Description

The MVME240x is a VME processor module equipped with a PowerPC
604 RISC (MPC750) microprocessor.
As shown in the
features desirable in a computer system—including Ethernet and debug
ports, Boot ROM, Flash memory, SDRAM, and interface for two PCI
Mezzanine Cards (PMCs), contained in a one-slot VME package. Its
flexible mezzanine architecture allows relatively easy upgrades of the I/O.
There are four standard buses on the MVME240x:
As shown in
provides the interface from the Processor Bus to the PCI. A W83C553
PCI/ISA Bridge (PIB) Controller device performs the bridge function
between PCI and ISA. The Universe ASIC device provides the interface
between the PCI Local Bus and the VMEbus. Part of the Hawk ASIC is the
ECC memory controller.
The Peripheral Component Interface (PCI) local bus is a key feature. 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).
