Abstract

The invention provides a routing determination method for a ring interconnection structure. The method comprises the following steps: acquiring a logic node number of a current chip on a mainboard; skipping the current chip in the routing table to the routing item of the corresponding chip, and setting the routing item to be not less than the numerical value of the maximum chip number supported bythe mainboard; sequentially calculating jump distances between the plurality of chips and the current chip along a first direction and a second direction of the annular interconnection structure respectively; and when the jump distance is smaller than the current routing item, determining the jump distance as the routing item of the current chip jumping to the corresponding chip. According to theinvention, the routing path between the chips can be effectively calculated without pre-determining the total number of the chips of the whole annular interconnection structure.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a method and device for determining a route of a ring interconnection structure. Background technique [0002] The multi-chip ring interconnection can be the interconnection of multiple single-chip packages (SCM), or the interconnection of one or more homogeneous multi-chip packages (MCM), or even one or more heterogeneous multi-die package (SIP) interconnection. Usually, in a ring interconnection structure, there are two routing paths between any two CPUs. In order to improve communication efficiency, the lengths of these two paths need to be calculated separately and the shorter one should be selected. [0003] In the routing determination method in the prior art, it is necessary to predetermine the number of chips as a parameter in the routing determination process, and it is difficult to determine the routing path if the total number of chips in the entire rin...
