Overview
The Synopsys DesignWare® USB Device Controller (UDC) is a set of synthesizable building blocks that ASIC/FPGA designers can use to implement a complete USB device interface.
The UDC is fully compliant with revision 1.1 of the USB specification.
By utilizing Synopsys' production-proven UDC, designers can significantly reduce development time and engineering risk and bring their USB-based solutions to market faster.
The UDC can be customized and optimized for a specific application. In addition, the design can be easily migrated to almost any technology in a relatively short period of time.
Synopsys' UDC bridges an industry-standard USB interface to a simple read/write parallel interface.
The simple interface shields the designer from the complexities of the USB protocol, and makes it easy to integrate the UDC to the customer's target application.
