Abstract
A bidirectional bus structure includes a first multiplexer path propagating signals in a first direction and a second multiplexer path propagating signals in a second direction. For one embodiment, the bus structure further includes a circuit for selectively combining the signals on the first and second paths and selectively propagating the signal on one of the first and second paths. For another embodiment, the bus structure further includes a logic gate for combining the signals on the first and second paths and a circuit for selectively propagating the signal on one of the first path, the second path, and an output signal of the logic gate. For both embodiments, the present invention allows multiple signals to use the bus without contention, thereby providing an extremely flexible interconnect routing resource. This bidirectional bus can selectively drive signals onto the general interconnect as well as onto a system bus in a configurable system on a chip.
