8.4 Scaler
The High Performance video Scaler (HPS) is based on the system as implemented in
previous products, but with some aspects enhanced. Vertical upsampling is supported
and the processing pipeline buffer capacity is enhanced, to allow more flexible video
stream timing at the image port, discontinuous transfers, and handshake. The internal
data flow from block to block is discontinuous dynamically, due to the scaling process.
