To demonstrate prototypes of devices with USB 3. 0

At the same time, with the publication of the first edition of the USB specification 3. 0 at San Jose (California, USA) launched the conference SuperSpeed USB Developers Conference. The event was considered by software and hardware architecture of the new interface, its dignity on Compared with predecessors, cables and connectors, power management and other features. But the most interesting part, perhaps, was the demonstration of the developers of prototypes of devices with USB 3. 0. The company Fresco Logic has developed IP-core (structural units ready for the chips) for host controllers and USB 3. 0. Their use has been designed demonstration system with a programmable FPGA-chips Xilinx. Note to the Intel Developer Forum, held in San Francisco in August this year, Fresco Logic has already demonstrated such a system, which was able to transmit data at speeds up to 350 Mbps. Now the company has refined its development. One of the key innovations was the use of coaxial cable to connect the host and device. his least interesting and demonstrated the company PLDA. Her prototype, also representing a combination of IP-cores implemented on the FPGA-chip, was connected to a monitor. As shown in the photo below, the data transfer speed is 452 Mb/s, which is far from theoretical maximum of 600 Mb/s, but still very good at this stage. One of the largest developers of electronic automation company Synopsys went further and his colleagues demonstrated the transfer of uncompressed Full HD-video (1080p, 30 k/s) using the USB interface 3. 0. According to its engineers, data transfer speed of the system exceeds 450 MB/sec. Synopsys plans to add IP-kernel used in the prototype, in its product DesignWare SuperSpeed USB IP, which it will begin to supply customers in the second half of 2009. finally recall that the entry first consumer product segment with USB 3. 0 expected no earlier than 2010.
