DVMT Mode Select
The CMX158886 supports Dynamic Video Memory Technology (DVMT). DVMT allows the CPU to allocate memory to system processing or graphics processing on the fly based on changing processing requirements.
For example, a graphics intensive program will require the operating system to request a larger amount of video memory than one that does not require large amounts of graphics processing. For the graphics intensive process, DVMT will allocate a larger portion of system memory. When the process is complete, DVMT will allocate the memory back to the system.
The CMX158886 supports three
•Fixed Mode: A fixed amount of system memory is reserved for video.
•DVMT Mode: Video memory is dynamically allocated as needed.
•Combo Mode: A fixed amount of memory is allocated, but more can be claimed as needed.
