SoC On-Chip Network

Efficient data transmission architecture inside a chip

SoC On-Chip Network

Overview

As modern System-on-Chip (SoC) designs integrate an increasing number of heterogeneous processing and memory components, efficient on-chip communication has become essential for achieving scalable performance and energy efficiency. We investigate high-performance and energy-efficient Network-on-Chip (NoC) architectures for efficient communication among components in complex SoC systems. Our research includes workload-aware routing, communication optimization, resource management, and network architectures tailored to the characteristics of emerging SoC workloads.
