Detailed Description

Smart tile cache with LRU eviction for efficient memory management.

Performance Optimizations:

• LRU eviction policy to keep frequently used tiles in memory
• Configurable cache size to balance memory usage and performance
• O(1) tile access and insertion
• Automatic cache management with minimal overhead
