1. Introduction：

The IP Core is a studio  quality video scaler capable  of generating interpolated output images from 16 x 16 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 video scaler in accordance with the valid-ready pipeline protocol.  Pixels are transferred into the scaler on a rising clock-edge when pixin_val  is high and pixin_rdy is high.  As such, the pipeline protocol allows both input and output interfaces to be stalled independently.

The scaler is partitioned into a horizontal scaling module in series with a vertical scaling module .

Application

• Support for the latest generation video formats with resolutions of 4K and above
• Video scaling for flat panel displays, portable devices, video consoles, video format converters, set-top boxes, digital TV etc.
• Conversion of all standard and custom video resolutions such as HD720P to HD1080P, XGA to VGA etc.
