An AI Accelerator is a specialized hardware unit or system designed to speed up AI applications, particularly neural network computations, machine learning algorithms, and data processing tasks. These accelerators are optimized for parallel processing and high-throughput computations, making them more efficient than general-purpose CPUs for AI tasks. They include Graphics Processing Units (GPUs), Tensor Processing Units (TPUs), and Field-Programmable Gate Arrays (FPGAs).
A prominent example of an AI Accelerator is Google’s Tensor Processing Unit (TPU). TPUs are custom-built ASICs (Application-Specific Integrated Circuits) designed specifically for TensorFlow, an open-source machine learning framework. They are optimized for the high-volume, high-speed computations required in deep learning, providing significant improvements in processing time and power efficiency compared to traditional computing hardware.
