Channel Paradigm

The Channel Paradigm is a versatile framework for managing concurrent tasks and resources in a 64-bit SDL3 environment. Channels are non-blocking, reentrant, full-duplex pipes written in C or assembler, supporting diverse operations like GPU blitting, I/O, media processing, and system events. Each channel operates independently, communicating via ring buffers and synchronized with HyperLock.

Key Features

• Non-Blocking: Channels use asynchronous I/O (DoIO, SendIO), avoiding stalls.
• Reentrant: Safe for recursive calls, enabling complex task chaining.
• Full-Duplex: Separate read/write buffers (ch_read, ch_write) for simultaneous communication.
• Concurrency: Channels run in parallel, with HyperLock atomics and pthread mutexes for synchronization.
• Resource Management: MemoryChannel allocates resources (GPU_MEMORY, IPC_MEMORY) via MemoryHandle.
• Extensibility: Supports GPU tasks (GraphicsContext), media (MediaChannel), URLs (URLChannel), and more.

Integration with SDL3 and Vulkan

Channels integrate with SDL3 for rendering (SDL_Texture, GraphicsContext) and Vulkan for GPU tasks (SPIRVChannel in SSBOs). Each channel’s Runtime (init, run, paint) defines its lifecycle, making it adaptable to tasks like blitting, event handling, or streaming.
