USB 3.0 Demos Feature 450MBps Speed, Non-compressed HDTV Transmission
A number of companies demonstrated USB 3.0 (SuperSpeed USB) data transmissions using prototype circuits at the SuperSpeed USB Developers Conference, a meeting for developers that took place in San Jose, California, from Nov 17 to 18, 2008.
Especially, they were demonstrated by IP core vendors in an effort to sell prototypes to developers as FPGA-based systems for development and verification. Though no company has developed a system that uses a USB 3.0 cable or connector, the level of completion is gradually increasing.
PLDA demos 450 Mbytes per second
Fresco Logic Inc prototyped IP cores for USB 3.0 hosts and device controllers and exhibited them as an FPGA-based demo system. The company displayed data transmissions using this system at the IDF (Intel Developer Forum), which took place in San Francisco in August 2008 (See related article).
This time, Fresco Logic improved the technology by, for example, using a coaxial cable for communications between the host and the device. The company can ship the system if requested, it said.
PLDA Inc of France also exhibited a prototype system that drives a USB 3.0 IP core on an FPGA board. The company proved on a monitor that the system can achieve an effective data transmission speed of more than 450 Mbytes per second. PLDA is ready to ship the system as a product, too, it said.
Synopsys Inc prototyped an HDTV video transmission system based on USB 3.0 and demonstrated a transmission of non-compressed 1080p 30fps HDTV video via USB 3.0. Its effective data transfer rate surpasses 450 Mbytes per second, the company said.
Synopsys is planning to add the IP used in this system to its "DesignWare" IP core and verification IP series lineup as the "DesignWare SuperSpeed USB IP" and to start shipping it in the second half of 2009.
At this year's SuperSpeed USB Developers Conference, which was attended by about 500 engineers and marketing people, a large number of attendees packed into the room where the prototype systems were exhibited. According to USB-IF's spokesperson, the turnout far exceeded the previous record for attendance at any USB-related meeting for developers.
