Connectivity software solutions provider Jungo Ltd has announced that its USBware for SuperSpeed USB 3.0 stacks will be integrated with the Synopsys DesignWare SuperSpeed USB IP offering. The result is a complete turnkey solution for silicon manufacturers.

USB 3.0, also known as SuperSpeed USB, is the new standard USB protocol. It features several improvements compared to the "High Speed" USB 2.0 protocol. These include bandwidth of up to 5.0 Gb/s (compared to 480 Mb/s for USB 2.0), improved power efficiency and management, increased power supply capability to devices, and optical as well as traditional USB-wire interconnection.

USB 3.0 is physically and functionally backward-compatible with USB 2.0 and can support devices complying with older specifications. USB 3.0 devices will operate in USB 2.0 modes with USB 2.0 hosts. Because SuperSpeed USB 3.0 is up to 10 times faster than its predecessor, transferring an HD movie (27GB) now takes about 70 seconds instead of 15 minutes with USB 2.0. This performance boost is most significant for Flash-based devices such as digital storage, cameras, media players and mobile phones.

As part of USB 3.0, a working group has been formed for the development of the next-generation mass storage specification named Mass Storage UASP. The throughput will be achieved by using a combined solution including a 3.0 stack and a UASP class driver.

"Our collaboration with Jungo allows designers to have early access to high-quality IP and software solutions that help them successfully implement SuperSpeed USB 3.0 into their SoCs with less risk," said Ed Bard, Senior Director of Marketing, DesignWare Digital IP & Memory at Synopsys. "By providing a fully interoperable hardware and software solution, we are enabling the design community to quickly benefit from the high throughput advantages of the SuperSpeed USB interface."
