Product Brief
Benfits Overview
Zoran's Scaler-1 is a silicon efficient, cost effective intellectual
Scale-1 has two modes, upscale mode and downscale mode. In
either mode the horizontal and vertical scaling ratios can be
programmed independently.
property core for IC designs requiring the video scaling function. The
Scaler-1 Video Scaler IP Core is a programmable up/down scaler
designed to scale between various TV and display resolutions.
