ANAHEIM, Calif. --inSilicon Corp. today demonstrated a working, multi-vendor implementation of the new Universal Serial Bus (USB) 2.0 specification, featuring a Hewlett-Packard ScanJet scanner using an FPGA-based inSilicon USB 2.0 device core (UDC) transmitting a scanned image to a PC at bursts of 480 megabits per second.
This rate is 40 times faster than the current USB 1.1 specification (see April 27 story). USB 2.0 is fully compatible with USB 1.1. USB enables cost-effective, outside-the box connectivity with hot-swap capability for industrial, consumer, embedded, PC and PC peripheral products. USB requires a host to manage and control bus traffic, and peripherals such as printers, scanners and digital cameras to communicate with the host.
The HP USB 2.0 capability, demonstrated at the USB 2.0 Developers Conference in Anaheim, is enabled in the scanner demonstration through an inSilicon device controller, operating in conjunction with a NEC Corp. USB 2.0 PHY test chip, communicating via a standard USB cable to an NEC host controller mounted on a PCI card in a PC.
"We are excited that HP chose inSilicon as the development collaborator for demonstrating USB 2.0 device functionality," said Eric Huang, USB product marketing manager at inSilicon. "This example of end-to-end USB 2.0 transfers, provides designers with a silicon-based verification of inSilicon's TymeWare USB 2.0 device controller capability."
"The demonstration shows high bandwidth for serious multimedia applications together with the ease of use consumers want," said Takahiro Tokuume, senior manager in NEC's Solution Engineering Division, and member of the board of directors of the USB Implementers Forum, Inc. "Now that we've all shown the first working USB 2.0 devices, the next stage is to get it into PCs for the Christmas season."
