# Virtual GPU (vGPU) Project This project aims to build a fully functional software-defined GPU (vGPU) using Python, without relying on any physical GPU hardware or existing low-level graphics APIs (like CUDA, Metal, Vulkan, or OpenGL). The vGPU is designed to simulate the behavior of a real GPU, including its core components, memory hierarchy, and parallel processing capabilities. ## Project Goals * **Software-Defined Hardware**: Replace traditional GPU hardware components with pure software abstractions. * **Massive Parallelism Simulation**: Simulate 50,000 processing cores and 800 Streaming Multiprocessors (SMs). * **High-Bandwidth Memory Abstraction**: Implement a 500GB GDDR7 memory abstraction using symbolic memory management. * **Graphical and AI Processing**: Capable of processing graphical logic, AI matrix operations, and rendering output. * **Modular Architecture**: Designed with distinct modules for clear separation of concerns and extensibility. ## Modules Overview This project is structured into several key modules, each responsible for a specific aspect of the vGPU's functionality: * `vgpu.py`: The core GPU processor, managing overall state, workload distribution, and the main GPU tick cycle. * `vram.py`: The video memory module, abstracting 500GB of GDDR7 memory using symbolic representation and efficient data handling. * `driver.py`: The CPU-to-GPU command interpreter, responsible for receiving and queuing commands from a virtual CPU. * `render.py`: The pixel renderer, implementing the software raster pipeline for drawing primitives and images. * `ai.py`: The simulated AI accelerator, handling matrix and vector operations using the vGPU's simulated parallelism. * `shader.py`: Provides a mechanism for simulating programmable shader logic. * `display.py`: The output system, handling the presentation of rendered frames to a display (e.g., WebSocket to JS canvas, GUI window, or image files). * `bus.py`: Simulates memory movement and data transfer logic between different logical components. ## Getting Started Further instructions on setting up the environment, running examples, and contributing will be provided as the project develops.
