What Is Pci Express

PCI Building Thinner Interconnect for Handheld Devices

The PCI-Express standards-setting organization is creating a thin interconnect that would link mobile devices such as smartphones and tablets to external peripherals, the organization's chief said on Monday.

The cable interconnect will enable data transfers between host devices and external devices at speeds of up to 8G bps (bits per second), said Al Yanes, president and chairman of the PCI-Special Interest Group (PCI-SIG). The organization hopes handheld devices equipped with PCI-Express ports will reach the market by 2013.

The PCI-Express protocol is used inside PCs for high-speed data transfers between components and this is the first time the organization is developing interconnect technology for handheld devices, said Yanes, who is also a distinguished engineer at IBM. Consumer handheld and mobile devices ship in larger volumes than PCs and the new technology could expand the horizons of PCI technology. "This will be a new opportunity for us," Yanes said.

The new interconnect will initially use copper wires for data transfers over short distances, with the possibility of upgrading to optical cables in the future. Yanes declined to comment on the type of external peripherals that would benefit from this interconnect, saying details about the specification are still being worked out. High-level goals have been established and the organization hopes to provide further information in the next three months.

The new interconnect would likely mean that devices would need a new port to connect peripherals. It will compete against existing technologies such as USB, which is found in many tablets, and Thunderbolt, an interconnect technology developed by Intel and Apple that will reach handhelds in the future. Thunderbolt already supports PCI-Express, but PCI's new mobile interconnect is independent of Intel's technology, Yanes said.

"[Intel's] doing their thing," Yanes said. "We build technology because our members want it."

There's been a growing demand for high-performance buses such as Thunderbolt and eSATA in PCs and that trend is also trickling into mobile devices, said Dean McCarron, principal analyst at Mercury Research.

"Targeting low-cost and making it widely licensed is a key ingredient for success," McCarron said. "Given that they are targeting mobile devices, it is a part of the industry that is attracting more development."

PCI-SIG has strong backing with more than 800 members, which could help build momentum around the technology, Yanes said. The interconnect will also be inexpensive for device makers to license and implement, which could further spur adoption of the technology, Yanes said.

Nothing new. Of course the US needs to bring the bright and the best. Yes, I agree with you the US apparently doesn't have the necessary number of people with advanced degrees in science right now. I never told you to shut down the H1B or decrease the numbers. I am just saying, can people respect the other side and suggest more sensible mechanisms ? Can one understand that an automatic increase of 20% per year can cause hardship to citizens caught in a future and unexpected recession ? That's all I am saying. means any United States academic or professional degree or a foreign equivalent degree above that of baccalaureate. A United States baccalaureate degree or a foreign equivalent degree followed by at least five years of progressive experience in the specialty shall be considered the equivalent of a master's degree. If a doctoral degree is customarily required by the specialty, the alien must have a United States doctorate or a foreign equivalent degree. First of all, thanks for converting my argument about Europeans and native peoples into Muslims and non-Muslims. Shows us where our respective prejudices and biases lie. I am very happy when my comments on any situation are turned into a broad 'us vs them' thing. It just shows us that our primitive and primal instincts from the time when we split from the apes are still alive and kicking in some people. Its pretty fascinating for me. Secondly there is a difference between military strikes (retaliatory or otherwise), and acts of massacres. Pretty much the same as there is a difference between military confrontation and ethnic cleansing. If you condone and defend the latter, then you are pretty much defending ethnic cleansing. Striking Hamas targets are military strikes. Holing up a hundred members of an extended family into a house, and then destroying the house is an act of massacre. When we defend acts like the latter one, we defend ethnic cleansing. About poisoning kids by extremists, I agree that they are poisoned from very childhood. But killing them is not a solution - never. If it is a problem with 1 or 2 persons, you can work on them and get them out of poisoned mind. Can't work on mass. Thats why B****ds who have their personal benefits associated, always associate these poisons with religion to expand their own empire. Misguided muslim people need to and will understand one day that they are breeding dangerous new generations and is hurting themselves.
