The Tori-connected mESH (TESH) Network is a k-ary n-cube network of multiple basic modules, in which the basic modules are 2D-mesh networks that are hierarchically interconnected for higher level k-ary n-cube networks. Many adaptive routing algorithms for k-ary n-cube networks have already been proposed. Thus, those algorithms can also be applied to TESH network. The authors have proposed three adaptive routing algorithms; channel-selection, link-selection and dynamic dimension reversal - for the efficient use of network resources of a TESH network to improve dynamic communication performance. In this paper, they implement these routers using VHDL and evaluate the hardware cost and delay for the proposed routing algorithms and compare it with the dimension order routing.
