SCALE1

Video Scaler IP Core

SCALE1 is a fully-programmable up/down scaler designed to scale between various TV and display resolutions.
 

Overview

Zoran’s SCALE1 Video Scaler IP Core is a programmable up/down scaler designed to scale between various TV and display resolutions. SCALE1 has two modes, upscale mode and downscale mode. In either mode the horizontal and vertical scaling ratios can be programmed independently.
