Video Rotation Function

The VPC-4 is a video rotator for converting landscape rasters to portrait format and for converting portrait rasters to landscape format. In addition to rotation by 0, 90, 180 or 270 degrees, optional image mirroring is also supported. The VPC-4 can be used standalone or in conjunction with the VPC-1 Deinterlacer and VSC-1 Scaler IP cores to provide a complete portrait display solution. When used in conjunction with the VPC-1 Deinterlacer, the memory interface can be shared to allow for concurrent deinterlacing, scaling and rotation on a single bus.

The VPC-4 is available with complete Verilog source code and Verilog test bench as part of the license. Integration and programming guidelines are also included backed up by expert technical support.

A VPC-4 reference design is available for standard development kits from Xilinx and Altera for demonstration and evaluation purposes. The design includes a built-in user interface with embedded OSD to simplify access to key features of the IP. In addition to simplifying the evaluation of the VPC-4 IP core, the design also serves as a template for customer application development.
