Zoran's Scaler-1 is a silicon efficient, cost effective intellectual
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.
Scale-1 has two modes, upscale mode and downscale mode. In
either mode the horizontal and vertical scaling ratios can be
programmed independently.
Features
•
Downscaling
– Input image filtered by programmable anti-alias filter
– Able to downscale from 1080i or 720p input to 480p ,720p,
640x480 or other custom input and output format sizes
– Downscaling ratios of 1x to 8x or more
– Able to scale images of maximum input size 4096 x 2048
• Text and activity detectors allow for precise scaling of feature
details while preserving text sharpness
• Eight (8) 1920 byte external line buffers required
• Approximately 170,000 NAND gate equivalents
•
Upscaling
– 2-D luma input image gradient used interpolate along edges
and slopes
– Able to scale from 480p input to 720p, 1080i, 800x600,
1024x768 or other custom input and output format sizes
– Anamorphic scaling mode provides smart upscaling from 4:3
aspect ratio to 16:9 aspect ratio
– Programmable scaling ratio of 1x to 4x or greater
– Maximum image output size of 2048x2048
