摘要:
A high performance interconnect that utilizes dynamic driver technology is capable of reduced power operation during periods of low data switching activity. Circuitry is provided that limits the performance of an evaluation operation in the dynamic driver circuitry to clock cycles during which a present input bit of the interconnect differs from a previous input bit. Thus, the evaluation operation and subsequent precharge of the driver output is performed sparingly during periods of low data switching activity. An output circuit is also provided for decoding the data stream flowing through the interconnect at the receiver end thereof. Using the principles of the present invention, it is possible to achieve the performance advantages of dynamic drivers with the switching activity of interconnects that use static CMOS technology.
