1. Introduction：

This IP is a very high quality video scaler capable of generating interpolated output images from 16x16 up to 2¹⁶  x 2¹⁶  pixels in resolution. The architecture permits seamless scaling (either up or down) depending on the chosen scale factor. Internally, the scaler uses a 24-bit accumulator and a bank of polyphase FIR filters with 16 phases or interpolation points.  All filter coefficients are programmable, allowing the user to define a wide range of filter characteristics.

Pixels flow in and out of the scaling engine in accordance with the valid-ready pipeline protocol.As such, the pipeline protocol allows both input and output interfaces to be stalled independently.

The scaler is partitioned into a horizontal scaling section in series with avertical scaling section.

Application

• Conversion of popular video formats to any other resolution such as VGA to XGA, SVGA to HD1080 etc.
• Picture in Picture (PiP) applications
• High quality 24-bit RGB/YCbCr video scaling
