Enhanced PCI Express Technology

IBM and Intel with support from dozens of other companies, have developed a proposal to enhance PCI Express* technology to address the performance requirements of new usage models, such as visualization and extensible markup language (XML). The proposal, codenamed “Geneseo,” outlines enhancements that will enable faster connectivity between the processor — the computer’s brain — and application accelerators, and improve the range of design options for hardware developers. Applications that will benefit include visualization, such as complex weather modeling; math and physics, such as data intensive financial applications; and content processing, such as the encryption and decryption of communications infrastructure data.

The proposal, codenamed “Geneseo,” outlines enhancements that will enable faster
connectivity between the processor — the computer’s brain — and application
accelerators, and improve the range of design options for hardware developers.
Applications that will benefit include visualization, such as complex weather
modeling; math and physics, such as data intensive financial applications; and
content processing, such as the encryption and decryption of communications
infrastructure data.

“IBM is co-founding a new open standard for attaching accelerators and
co-processors to server platforms,” said Dr. Tom Bradicich, IBM fellow and chief
technology officer, System x™ and BladeCenter® Servers. “Like PCI-X, InfiniBand
and PCI Express, this new architecture defines a standards-based approach for
improving general purpose server accessibility within new and emerging
application areas, such as encryption, visualization, XML and complex
mathematical modeling.”

“Five years ago Intel, along with IBM and other industry leaders, laid out a
10-year vision for an open, standards-based interface for the entire computer
industry,” said Pat Gelsinger, senior vice president, general manager, Intel’s
Digital Enterprise Group. “In 2004, PCI Express was the first step and today is
the overwhelming choice for desktop, mobile and server systems. Geneseo is the
next step in this vision and will address new requirements and opportunities
that come with next-generation platforms.”

Geneseo is supported by key technology companies including Adaptec Inc., AGEIA
Technologies Inc., Altera Corporation, Broadcom Corporation, Celoxica, Cisco
Systems, ClearSpeed Technology, Dell, EMC Corporation, Emulex Corporation, HP,
Integrated Device Technology Inc., Lecroy Corporation, Linux Networx, LSI Logic,
Mellanox Technologies, Myricom, NetEffect, Novell, NVIDIA, PLX Technology, PMC-Sierra,
QLogic, Sun Microsystems, Synopsys, Tektronix, Xambala Inc., Xilinx Inc. and
Xtreme Data.

PCI Express technology was first delivered in client and server computing
platforms in 2004. Its introduction signaled the transition of computing
platform I/O from the parallel bus model that had existed since the PC
industry’s inception to a high-speed, serial I/O standard. Since this time,
millions of PCI Express-enabled platforms and devices have been delivered to
customers, and PCI Express has emerged as the industry’s choice for platform I/O
and internal interconnect connectivity.
