PAC-NoC: A Hierarchical Network-on-Chip for Efficient Parallel Aggregated Communication in Transformer Accelerators

In the era of Transformers and large language models (LLMs), communication bandwidth has superseded compute capability as the dominant architectural bottleneck. These workloads require frequent aggregated multicast, requiring the simultaneous delivery of distinct data streams to multiple processing element (PE) cluster...

CDCA: a column-serial and dual-engine collaborative accelerator for depthwise separable convolution

Results show that CDCA provides a low-power FPGA design point for DSC acceleration, making it suitable for resource-constrained edge inference scenarios and improving energy efficiency through a dataflow-driven architecture.

A novel simulated annealing based mapping for hybrid NoC-enabled DNN accelerators

A reconfigurable hybrid ring-shaped architecture (Rhr-NoC) to adapt to the large-scale data transmission patterns within accelerators and design a simulated annealing algorithm tailored to the hybrid ring-shaped architecture, providing a more rational scheme for mapping neural networks onto NoC platforms.
