Abstract:
1. A logic block that can perform two-input combinatorial logic comprising: a first transmission gate controlled by a second input to said logic block; a second transmission gate controlled by said second input to said logic block, said second transmission gate having as its input a first input to said logic block, wherein: based upon said second input to said logic block, the logic block outputs the signal passed by either said first or second transmission gate; the passed signal is selected from the group consisting of the first input, a low logic signal, a high logic signal, and their inverses; the first input, the low logic signal, and the high logic signal can be selectively routed to the output through the first transmission gate; and the first input, the low logic signal, the high logic signal, and their inverses can be selectively routed to the output through said second transmission gate.
