Systolic Array
Systolic arrays are parallel processing architectures designed to efficiently perform matrix multiplications, crucial for accelerating deep neural network (DNN) inference and training, particularly for convolutional neural networks (CNNs) like VGG and ResNet. Current research focuses on optimizing dataflow within these arrays (e.g., triangular input movement) to minimize memory access and energy consumption, improving reliability through fault tolerance techniques and efficient monitor placement, and developing adaptable architectures that handle both dense and sparse matrix operations with variable precision. These advancements are significantly impacting the performance and energy efficiency of DNN accelerators, enabling faster and more power-efficient AI applications.
