Defines VirtualFile and VirtualDir interfaces providing a clean abstraction over various storage backends (real filesystem, ROM, layered directories). This pattern is isolated and reusable in any project needing a modular filesystem layer, demonstrating good interface design and separation of concerns.

A template-based BitField class that allows type-safe access to individual bit fields within a word, with automatic shift/mask calculations. Used extensively in shader decoding, kernel structures, and hardware register emulation. Self-contained and easily extractable for any low-level bit manipulation need.

Base class for audio renderer commands (ICommand) with virtual Dump, Process, and Verify methods. This command pattern enables a flexible, testable audio processing pipeline where each effect (mix, reverb, limiter) is a separate command. The pattern is generic and could be reused in any signal-processing or pipeline-based audio system.

Implements a lock-free double-buffered dirty memory manager for GPU page tracking. Uses atomic operations and bitmasks to efficiently collect dirty pages between CPU and GPU memory. This technique is reusable in any high-performance application needing concurrent dirty-page tracking, such as virtual machine monitors or graphics drivers.
