PCI-SIG Announces PCI Express Architecture Performance Extension; Planned Specification Doubles Current Data Rate to 5GT/s.PORTLAND, Ore. -- The PCI-SIG(R), the Special Interest Group responsible for PCI Express A high-speed peripheral interconnect from Intel introduced in 2002. Note that although sometimes abbreviated "PCX," PCI Express is not the same as "PCI-X" (see PCI-SIG and PCI-X for comparison). As a result of the confusion, "PCI-E" or "PCIe" is the accepted abbreviation. (TM) architecture, announced today that the data rate for the next planned revision of the PCI Express specification will be 5 Giga transfers per second. This new specification extends the performance capability of its flagship I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output interconnect architecture to meet the anticipated system requirements To be used efficiently, all computer software needs certain hardware components or other software resources to be present on a computer system. These pre-requisites are known as (computer) system requirements and are often used as a guideline as opposed to an absolute rule. across computer and communication industry applications. The doubling of the data rate follows historical performance increases for I/O specifications in the industry. The PCI-SIG board of directors considered market requirements and technical analysis of a range of data rates to obtain the most feasible, highest performance, backward compatible Refers to hardware or software that is compatible with earlier versions of the product. Also called "downward compatible." Contrast with forward compatible. backward compatible - backward compatibility solution within the current PCI Express ecosystem. Platform implementation cost, high-volume manufacturability, system topologies, validation and interoperability were the key considerations studied by the PCI-SIG board members in the process to extend the PCI Express data rate to 5GT/s. Many of the leading electrical experts who developed the PCI Express 1.0a specifications have been chartered to draft the new specification. The PCI-SIG expects to deliver the new specification in the second half of 2005 in time for product introductions beginning in 2007. "The PCI-SIG continues to deliver on the promise of timely PCI Express enhancements to meet the ever-growing bandwidth requirements Bandwidth requirements (communications) The channel bandwidths needed to transmit various types of signals, using various processing schemes. Every signal observed in practice can be expressed as a sum (discrete or over a frequency continuum) of sinusoidal of the I/O industry," said Tony Pierce, PCI-SIG chairman. "The board of directors thoughtfully considered an array of technical and market data and arrived at the best decision for the next revision of the PCI Express architecture. We plan to deliver the new 5GT/s PCI Express specification consistent with our members' expectations for 100% backward compatibility See backward compatible. (jargon) backward compatibility - Able to share data or commands with older versions of itself, or sometimes other older systems, particularly systems it intends to supplant. , low-cost manufacturability and world-class compliance and interoperability." "The new 5GT/s PCI Express specification will enable the required performance boost for bandwidth-hungry applications such as cinema-quality graphics and multimedia, enterprise servers and storage, and multi-gigabit networking," said Ajay Bhatt, chairman of the PCI Express steering committee steer·ing committee n. A committee that sets agendas and schedules of business, as for a legislative body or other assemblage. steering committee Noun , responsible for managing the technical development and coordination of PCI Express specifications. "The electrical specification will introduce evolutionary methodologies to meet the technical challenges of running at 5 Giga transfers per second while maintaining compatibility with existing system topologies and silicon processes."

About the PCI-SIG The PCI-SIG is the Special Interest Group that owns and manages PCI specifications as open industry standards. The organization defines and implements new industry standard I/O (Input/Output) specifications as the industry's local I/O needs evolve. The PCI Special Interest Group was formed in 1992, and the organization became a nonprofit corporation nonprofit corporation n. an organization incorporated under state laws and approved by both the state's Secretary of State and its taxing authority as operating for educational, charitable, social, religious, civic or humanitarian purposes. , officially named "PCI-SIG" in the year 2000.
