Video Scaler with Shrink and Zoom Support

Overview

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. Complete source code including Verilog and bit-accurate C models are available as part of the license. An FPGA based demo platform is available for evaluation purposes.
