Evatronix pushes speed up on USB 3.0 IP

Polish semiconductor intellectual-property (IP) provider, Evatronix demonstrated at the IP-ESC conference in Grenoble this week an implementation of its USB 3.0 device controller that could transfer data at more than 90 per cent of the protocol’s peak bandwidth.

Running on a Xilinx Virtex5 field-programmable gate array, the IP core sustained a throughput value of more than 430MB/s: 94 per cent of the maximum value achievable with no processor or software overhead. According to Evatronix, the controller has also passed all available USB-IF verification tests with certified xHCI host controllers from NEC and Fresco Logic.

Dariusz Kaczmarczyk, USB product line manager at Evatronix, said: “We are currently offering a working single chip FPGA solution that implements the SuperSpeed USB 3.0 Controller with least CPU overhead. This is a great opportunity for our customers to develop applications that will utilise the high speed edge of USB 3.0 to the highest possible extent”

The controller implements the OCP socket as the primary interface for both microprocessor and memory. Wrappers for popular system bus interfaces are available.
