Altera Stratix II Dev Board with SMSC USB 2.0 ULPI PHY daughter card (upper right corner) implementing Vreelin USB 2.0 High Speed Device I/F

Vreelin’s USB 2.0 device core for Altera FPGA’s integrates into the Altera Qsys/SOPC Builder/NIOS2 Development kit. This allows developers to quickly add a USB 2.0 interface into a NIOS2 project. The core has a small footprint of 1500 LE’s on current generation Altera FPG’s and uses a ULPI compliant external PHY that requires only 12 pins. The core attaches to the Altera Avalon bus as a slave device and appears as RAM. Pushbutton system configuration with SOPC Builder allows the designer to add, delete or modify the core. Multiple cores can be added to a design as needed. Fully plug and play compliant, the Vreelin USB 2.0 core includes working USB Chapter 9 firmware, demo Mass Storage Device Class firmware, and Windows device driver software which can be customized by the designer for his application needs.  The device driver supplies W32API ReadFile and WriteFile for data, and IOCTL calls for control. Multiple handles can be open to the device driver so that the user’s application can be in multiple programs.

Small and fast, the core supplies control endpoint 0 plus 7 end points for the user’s application with double buffering on each end point. The maximum packet size for Bulk and Interrupt endpoints is 512 bytes. ISO endpoints can be 1024 bytes. Up to 16 KB of TriMatrix Memory can be allocated as needed. As supplied the core uses 4 TriMatrix Memory blocks or 8KB. The type of each endpoint (bulk, interrupt, or ISO), the max packet size for each endpoint, and the endpoint’s buffer location in dual port RAM is configured by the firmware.  HDL source code for the dual port RAM module is provided to allow the designer to minimize the foot print as required. To meet special circumstances, the core can be custom built by Vreelin Eng. with more or less than 8 endpoints and with other special features as required such as custom hardware interfaces for specific endpoints. The core sustains USB 2.0 high speed transfer rates up to the limits of the USB bus and is certified USB 2.0 Logo Compliant.
