6U CompactPCI Board features Flip-Chip Pentium III
Concurrent Technologies has announced the release of the PP EMB/P34 Peripheral Slot Controller CPU board, a single slot 6U CompactPCI Board featuring the Flip-Chip Pentium III processor.
Hot-Swap PMC Carrier allows continuous operation
The PP PMC/002 is designed to provide a cost effective and flexible approach to implementing standard and custom I/O requirements using industry standard PMC modules in CompactPCI systems.
The improved networking performance of the CL PMC/551 is achieved through the use of two Intel 82551QM Fast Ethernet controllers.
These controllers, which have 3Kbyte FIFOs and can operate full-duplex, enable the CL PMC/551 to exhibit improved performance by offloading the TCP, UDP and IP checksums and include support for TCP segmentation offload for operations such as large send.
The controllers also have improved bit error rate performance and improved dynamic transmit chaining with multiple priorities transmit queues.
The CL PMC/551 is a single-size card and is compliant with the CMC (Common Mezzanine Card) specification.
The adapter complies with the PCI specification, features 3.3 or 5V signalling, 32bit transfers, operates at 33MHz and has bus master capability.
In addition, base address and interrupt selection is software configurable.
A boot EPROM socket is also provided.
The adapter's physical connection to an Ethernet network is through industry standard RJ45 connectors that allow connection to low cost Cat 5 cabling.
This board can be used with Concurrent Technologies' CompactPCI, VME, Multibus II, or with any other PMC compliant host board.
Operating systems supported include Windows NT, Windows 2000, Windows XP, Windows XP Embedded, VxWorks, Linux and UnixWare.
