ABSTRACT:
A cross-point switch fabric slice (100) includes 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 gated buffers (146-160) in the first gated 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 cross-point switch fabric slice (100), longer internal connections are driven by more capable buffers.
