Abstract
A method and system for rendering a frame to be displayed on a screen includes a memory-sink mechanism configured to store a copy of a screen image in memory, a snoop mechanism configured to monitor a system parameter, a controller configured to switch between first and second operation modes in response to the snoop mechanism detecting a change to the system parameter, and a rendering mechanism to retrieve the copy of the screen image when the system operates in the second mode of operation.
Claims18
A display system comprising:
- a memory-sink mechanism configured to store a copy of a screen image in memory;
- a snoop mechanism configured to monitor a system parameter;
- a controller configured to switch said system between first and second modes of operation in response to said snoop mechanism detecting a change to said system parameter;
- a retrieval mechanism to retrieve said copy when said system operates in said second mode of operation.
A method comprising the steps of:
- storing a copy of a screen image in memory;
- monitoring a system parameter;
- switching between first and second modes of operation upon detecting a change to said system parameter;
- retrieving said copy in said second mode of operation.
