Supervised Models Focus: The paper primarily highlights supervised models, which form a subset of AI and machine learning, allowing computers to learn from data. Models are categorized as either supervised or unsupervised.
-
Transformer Models: Since 2017, Transformer models have revolutionized language processing by using attention mechanisms to handle long-term text dependencies. Google’s introduction of the Transformer model for text translation in 2017 marked a significant milestone.
-
FPGA Accelerators: The survey provides an extensive list of FPGA-based research (marked with A-T numbering) aimed at accelerating Transformer networks. Examples include FTRANS, which achieved significant speedups and energy efficiency over CPU and GPU implementations, and multi-head attention, which focused on accelerating the most computationally intensive parts of Transformer networks.
-
GPU and CPU Accelerators: Research like TurboTransformers, which optimized GPU performance for Transformer models, and techniques to accelerate Softmax layers in Transformer networks, are highlighted. These advancements have led to notable improvements in inference speed and reduced off-chip memory traffic.
-
ASIC Accelerators: The paper also covers ASIC-based accelerators, such as A3 and ELSA, which showed significant acceleration over CPU implementations and improved energy efficiency. SpAtten is noted for reducing computation and memory access in large language models.
The survey provides a detailed analysis of each framework, comparing their technical aspects, processing platforms (FPGA, ASIC, memory, GPU), acceleration, energy efficiency, and performance (in GOPs). This information is crucial for understanding the current state of hardware acceleration in the context of LLMs and its implications for future developments in AI and machine learning.
