One of the best enhancements to computers in the last 10 years has been the addition of USB ports. If you purchase a desktop computer, Speed Up Dsl type of connection is probably used for the mouse, keyboard, and printer connections. In addition, many general purpose connections like a thumb drive use this port. One of the best attributes is that the connection can be made without restarting the computer.
USB is the most versatile and popular computer interconnect ever. To date, over 6 billion ports have been sold.
In its current format is known as USB 2.0. 2.0 has been the standard since 2002 and has a data transfer rate limit of 480 Mb/sec. That rate is good for most applications, but is wanting for applications like video.
"The future of computing and consumer devices is increasingly visual and bandwidth intensive. Lifestyles filled with HD media and digital audio demand quick and universal data transfer. tm net malaysia is an answer to the future bandwidth need of the PC platform." adsl modem Eisler, President of the chipset business unit at Advanced Micro Devices.
The new specification is predictably called USB 3.0 (also called "SuperSpeed"). 3.0 is capable of data transfer rtes of 4.8 Gb/sec (10X faster than 2.0). 3.0 is a version that is similar to PCIe Gen2 signal techniques, but with a connector cosmetically similar to the connector to which we Kuala Lumpur accustomed. A 30 internet usage policy HDTV movie that takes about 15 minutes to transfer with 2.0, will take Networking Broadband than 90 seconds with 3.0. The connectors were shown to the general public for the first time at last year's CES (Consumer's Electronics Show). Equipment designed to meet 3.0 will be backward compatible with 2.0 hardware, but when a 3.0 device is connected to a 2.0 device, the performance will be at 2.0 performance levels.
3.0 has more pins than 2.0 (9 instead of 4), but the connector remains compatible with the old form factor. Pins 1-4 are called the "USB 2.0 Pins" and Pins 5-9 are referred to as the "SuperSpeed pins". When interconnecting a USB 2.0 connector with a 3.0 connector, pins 5-9 will be open. There are two compare high speed internet access configurations for 3.0. "Standard A" connectors are fully compatible with 2.0. 3.0 devices are not required to be compatible with 1.1 and older devices. A color coding (Blue Pantone 300C) of the 3.0 connector is planned.
Applications
Synopsys has prototyped an HDTV transmission system based on 3.0. The company has demonstrated transmission of non-compressed 1080p at 30fps HDTV via 3.0.
Apple has Celcom Broadband Wireless 3.0 with built-in capabilities with the iPhone. There is firmware on the iPhone to facilitate connecting your laptop computer to the phone via a 3.0 connection. The iPhone can then be used as wireless modem for the computer. Apple says that this capability exists with the iPhone 3.0 OS, but details still need to be negotiated with carriers.
At least one laptop manufacturer is already integrating the new connector into their system. The latest versions of the Asus M50 laptop come equipped with 2 ports that are ready for the additional contacts. Asus has framed their system for 3.0, but the full system is not yet in place.
Consumer products utilizing 3.0 should become available later this year (2009), and in general use in 2010. The first products to market will probably be flash drives, digital music players, and digital cameras. Initially there will be a price premium for the new technology. In this case, it is justified, since it will be a significant challenge for the manufacturer to meet the specification requirements.
