Detailed Description

Data cache using tile based cache pages. The cache holds a number of of tiles. The maximum number of tiles hold can be configured. Tiles however will only be freed if a cleanup is explicitely triggered. So temporary overbooking can happen. This should assure that prefilling of tiles is possible even with a very low limit.

The cache will free least recently used tiles first,
