The VSC-1 is a high quality polyphase scaler which has been optimized for video and graphics applications. The scaler may be used in conjunction with the VPC-1 Video Processor and Deinterlacer IP core or with any other customer or third party IP. Support for both shrink and zoom modes allows full screen display of any video or graphics source as well as arbitrary resizing for PIP applications. Dynamically loadable coefficients provide maximum flexibility to optimize for different source types and to enable effects such as image sharpening. In addition, the core includes a number of Verilog parameters that allow it to be tailored at build time to satisfy specific requirements. Flexibility, robust design and rigorous testing combine to make the VSC-1 ideal for both consumer electronic and broadcast applications.
