CROSS-POINT SWITCH FABRIC AND SWITCH FABRIC SLICE

摘要

PROBLEM TO BE SOLVED: To provide a cross-point switch in which data transfer rate is not limited.;SOLUTION: A cross-point switch fabric slice 100 includes a multistage gated buffer tree 135 incorporating at least first and second serially connected gated buffer stages 136, 138. N inputs 102-116 connect to preselected gate buffers 146-160 in the first gate buffer stage 136. The multistage gated buffer tree provides a signal path from any of the N inputs 102-116 to at least one switch output 118 in response to gated buffer stage control signals for the first gated buffer stage 136 and gated buffer stage control signals for the second gated buffer stage 138. Generally, the number of gated buffers decreases from that of the previous stage. As an input signal propagates through the slice 100, longer internal connections are driven by more capable buffers.;COPYRIGHT: (C)2005,JPO&NCIPI
