TTM Memory Manager
Tungsten Graphics created the TTM memory manager, an advanced video memory manager that implements:
- Dynamic tracking of buffers referenced by active rendering commands.
- Full access to all addressable video memory for every 3D context.
- A fence facility for hardware synchronization.
- A guarantee that contents of textures and other video memory buffers will be preserved, and therefore require no backing store in main memory.
For more detailed technical information, please see the TTM Wiki.
