The Chimera GPNPU from Quadric stands as a versatile processing unit designed to accelerate machine learning models across a wide range of applications. Uniquely integrating the strengths of neural processing units and digital signal processors, the Chimera GPNPU simplifies heterogeneous workloads by running traditional C++ code and complex AI networks such as large language models and vision transformers in a unified processor architecture. This scalability, tailored from 1 to 864 TOPs, allows it to meet the diverse requirements of markets, including automotive and network edge computing.\n\nA key feature of the Chimera GPNPU is its ability to handle matrix and vector operations alongside scalar control code within a single pipeline. Its fully software-driven nature enables developers to fine-tune model performance over the processor's lifecycle, adapting to evolving AI techniques without needing hardware updates. The system's design minimizes off-chip memory access, thereby enhancing efficiency through its L2 memory management and compiler-driven optimizations.\n\nMoreover, the Chimera GPNPU provides an extensive instruction set, finely tuned for AI inference tasks with intelligent memory management, reducing power consumption and maximizing processing efficiency. Its ability to maintain high performance with deterministic execution across various processes underlines its standing as a leading choice for AI-focused chip design.
The Chimera Software Development Kit (SDK) by Quadric provides an extensive environment tailored for developing complex application code suited for the Chimera GPNPU. This SDK bridges conventional C++ code with machine learning algorithms, enabling seamless integration and optimization of AI models across various platforms. By supporting data-parallel algorithm development in familiar frameworks like TensorFlow and PyTorch, the Chimera SDK enhances developers' proficiency in transforming machine learning graphs into executable C++ code.\n\nCentral to the SDK's functionality is the Chimera Graph Compiler (CGC), a sophisticated tool that imports AI inference models and optimizes them for the Chimera architecture. This tool offers a comprehensive optimization process, from operator transformation to memory bandwidth utilization, ensuring peak performance and integration efficiency.\n\nDevelopers can deploy the Chimera SDK on private cloud environments or local systems, leveraging its cycle-approximate Instruction Set Simulator for profiling and tuning application workloads. This allows for in-depth analysis of cycle counts, data bandwidth usage, and power consumption, facilitating precision optimization for diverse machine learning workloads beyond initial deployment.
