Connecting IP blocks in complex system-on-chip (SoC) designs presents a central challenge due to the unique characteristics of these IP blocks. An effective approach for complex SoC designs entails a combination of different network-on-chip (NoC) designs, including crossbar, star, ring, tree, mesh, and torus configurations. Each of these designs has its own distinct advantages and limitations, encompassing factors such as cost, scalability, speed, and power efficiency. The choice of NoC design depends on the specific application, and there is no one-size-fits-all solution.
