    摘要: For one disclosed embodiment, a converter converts 2N-bit data into an N-bit value indicating a number of bits in the data that have a predetermined logical value. The converter includes N comparators, each determining whether the number of bits in the data having the predetermined logical value exceeds a respective one of a plurality of reference values. The N-bit value is generated based on the outputs of the comparators. For another disclosed embodiment, a first delay element delays a signal based on a number of bits in a data value having a predetermined logical value, and a second delay element delays the signal based on a number of bits in a reference value having the predetermined logical value. A comparator then generates a bit value based on the delayed signals.

    摘要: A low loss on-die interconnect structure includes first and second differential signal lines on one of the metal layers of a microelectronic die. One or more traces may also be provided on another metal layer of the die that are non-parallel (e.g., orthogonal) to the differential signal lines. Because the traces are non-parallel, they provide a relatively high impedance return path for signals on the differential signal lines. Thus, a signal return path through the opposite differential line predominates for the signals on the differential lines. In one application, the low loss interconnect structure is used within an on-die salphasic clock distribution network.

    摘要: An adder circuit includes a number of selectors and an adder. The selectors feed the adder with multiple input data bits. Each of the selectors includes a combination of a multiplexing network and a sense amplifier to select from a number of input values to generate the multiple input data bits. The combination of the multiplexing network and the sense amplifier acts as the state-holding element at the input of the adder, avoiding the overheads of an explicit latch stage.

    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.
