摘要
Three high performance implementations for an interlock collapsing ALU are presented as alternative embodiments. The critical path delay of each embodiment provides reduction in delay. For one of the implementations the delay is shown to be an equivalent number of stages as required by a three-to-one adder assuming a commonly available bookset. The delay for the other two implementations is comparable to the three- to-one adder. In addition, trade-offs for the design complexity of implementation alternatives are set out. The embodiments achieve minimum delays without a prohibitive increase in hardware.
