(.This paper establishes a functional analysis model of the on-chip network designed by Lixiang, and on the basis of which the on-chip cache optimization strategy and allocation algorithm are proposed. The simulation on the hardware implementation platform shows that the on-chip network analysis model established in this paper can well analyze the on-chip network communication delay and the blocking probability of the routing nodes. , in order to reduce the data overhead in the case of cache resources such as tides)
