The regular topology of mesh-based network-on-chip (NoC) provides flexible and scalable architecture for chip multiprocessor (CMP) systems. However, as the complexity of network increases, routing problems become performance bottlenecks. In the field of wide area networks (WANs), ant colony optimization (ACO) has been applied to an adaptive routing for improving performance and achieving load balancing...
Ant Colony Optimization (ACO) is a bio-inspired algorithm extensively applied in optimization problems. The performance of Network-on-Chip (NoC) is generally dominated by traffic distribution and routing. With more precise network information for path selection by using pheromone, ACO-based adaptive routing has higher potential to overcome the unbalance and unpredictable traffic load. On the other...
Three-dimensional network-on-chip (3D NoC), the combination of NoC and die-stacking 3D IC technology, is motivated to achieve lower latency, lower power consumption, and higher network bandwidth. However, the length of heat conduction path and power density per unit area increase as more dies stack vertically. Routers of NoC have comparable thermal impact as processors and contributes significant...
