Vreelin Engineering specializes in USB. We have over 16 years experience developing systems software, device firmware, and hardware in the USB arena. Our cores are specifically developed for use in FPGA's from Altera and Xilinx.
We include Windows and Linux device drivers and complete example firmware all in C source code format. These are not just demo's but complete working components usable as-is or as a solid starting point for further development.
All Vreelin USB cores are USB Implementer Forum Certified as USB 2.0 High-Speed Devices.
Vreelin USB cores all use the ULPI PHY interface and work best with SMSC USB PHY's.
Xilinx AXI Bus Interface support is available now! Please visit www.highipdesign.com for more information.
