Self Similar Cubic: A Novel Interconnection Network for Many-Core Architectures

The continuous improving of semiconductor technology integrates more processors into a single chip. While integrate multiple processors into a chip, the interconnection network of among the cores become a dominant performance bottleneck. Accordingly, this paper provides a new on-chip interconnection network, called Self Similar Cubic (SSC), for many-core architectures. By cooperating with proposed linking mechanism, routing algorithm, and switching architectures, SSC has better scalability, on-chip fabrication possibility, and high communication performance, than conventional on-chip networks, such as Mesh, and Hypercube. In this paper, the comparison of performance and area cost are proposed. The analysis results reveal that SSC can provide higher throughput and lower area cost than other on-chip networks. The performance per area cost of SSC is five times better than that of Mesh.
