thus reduces the speed because of the extra inputs to the mlrm for example if two les each have inputs to a mlrm in each direction then a total of four mlrms may be shared among two les in other words only two mlrms per le is required yet another approach that avoids increasing the number of fast inputs to the mlrm is to use different types of routing wires that have a larger set of routing directions for the mlrms fig8 a illustrates a method of using horizontal and vertical routing wires for reducing the number of mlrms in an lab as shown in fig8 a a t wire such as a th4 802 or a tv4 804 is driven in the center it can connect to other labs 100 or dims 108 along its length including stitching at the end in this case each le needs to drive one segment of th4 wire or one segment of tv4 wire reducing the number of mlrms per le from four to two which are shown as 806 and 808 in yet another approach a star wire s4 810 illustrated in fig8 b connects to both horizontal and vertical routing wires in addition the star wire s4 810.
