Wipro rolls out its USB 2.0 technology

BANGALORE: Wipro Technologies has made its high-speed Universal Serial Bus

(USB) 2.0 technology commercially available.

The USB 2.0 technology is driven by the market need for high-speed data

transfer between personal computers (PCs) and high performance peripherals and

broadband Internet services. This next generation interface standard has already

been widely embraced by market leaders like Intel, Hewlett Packard, Dell and

Microsoft among other USB Implementer forum members.

The USB 2.0 specification ensures very high performance serial data transfer

at rates of up to 480 Mbps, thus enabling high speed video capture and video

editing as well as faster storage. The technology is ideally suited for high

bandwidth applications like digital cameras, DVDs, mass storage devices,

printers, scanners and a host of other peripheral devices. The ‘plug and play’

nature of USB allows a user to add a new peripheral without going through an

elaborate configuration process.

Wipro’s USB 2.0 Device Controller is a Verilog synthesizable core,

available with a host interface that supports the PCI standard and can be easily

customized to other local host systems as well. The core is up to 40 times

faster than the older USB 1.x Devices, running at speeds of 480 Mbps compared to

speeds of 12 Mbps supported by the older USB 1.x Devices. It is fully backward

compatible with existing USB 1.1 Devices, thus making the user’s migration

from USB 1.1 to USB 2.0 easier.

It offers additional features like SoftDisconnect, an early warning system

for self detection/correction of faults without having to restart the system.

Double Buffering designed especially for Isochronous, Real Time, Data Transfer

to reduce the latency/delay in transmission and Auto Retry for failed packets, a

design aspect that ensures Quality of Service is another feature of the product.

Complementing the Device Controller is Wipro’s USB 2.0 software stack that

is fully compliant with USB specification Version 2.0 and is currently available

on VxWorks platform. The stack offers 1.5 Mbps low speed support for devices

such as keyboards and joysticks, 12 Mbps full speed support for faster devices

like scanners and printers and 480 Mbps high speed transfer rates for bandwidth

demanding applications.

"The development of the USB 2.0 Device Core and USB 2.0 Software Stack

will enhance our leadership position in the wireline connectivity space",

said Mr. Ramesh Emani, CEO of the Embedded & Internet Access Solutions

Division. "The core and software will add to our portfolio of successful

reusable components for wired applications. The USB 2.0 is a high-speed

connectivity solution and it reflects our commitment to work on cutting edge

technology."

Wipro has a complete set of USB technology enablers consisting of both host

and controller cores for USB 1.1 along with the USB 2.0 Device Controller Core

and software stacks. Wipro is also committed to develop the USB-on-the-go (OTG),

defined to make low power consuming portable devices USB compliant. Wipro’s

USB cores and software are thoroughly tested and can easily fit into any system

design. Wipro’s portfolio of USB IPs is supported by a vast spectrum of VLSI

and System design as well as embedded software expertise that allows us to offer

customers a comprehensive, end-to-end solution.
