A CPU that runs entirely on GPU
Summary
The article describes nCPU, a GPU-resident neural CPU where registers, memory, flags, and the program counter are tensors and every ALU operation is performed by trained neural networks. It details Neural Mode and Fast Mode, a GPU-native architecture with on-device execution and a suite of Metal kernel options, benchmarks, and a DOOM demo to illustrate performance. It also provides project structure, models, and testing information, highlighting a novel approach to AI hardware acceleration and neural computation.
