A distributed crossbar switch scheduler for on-chip networks
Kangmin Lee, Se-Joong Lee, Hoi‐Jun Yoo · 2004
A scheduling algorithm is proposed for a lightweight on-chip crossbar switch in on-chip networks. The proposed NA-MOO algorithm distributes the arbitration computing over all of the crossbar fabric nodes. Its implementation shows that it can reduce >60% area and >20% computation delay compared to the conventional round robin based SLIP algorithm. Its feasibility is analyzed by using an SoC for HDTV as an example. The proposed techniques are area-efficient and show higher performance for the on-chip interconnection networks.
