1.2 SM731 Graphics Controller

1.2.1 Overview

The SM731 is a low power 2D/3D display controller with 90, 180, and
270 degree hardware rotation. Silicon Motion's ReduceOn™ technology
for the SM731 implements functions in hardware that were previously
performed in software, allowing easier driver development. ReduceOn
technology intelligently monitors the activity on the device and optimizes
the power as necessary to maximize performance and power consumption.
This level of power management is possible since each functional block
and engine clock can be dynamically controlled to actively reduce the
overall power consumption.
