摘要： A dynamic bus architecture is provided. This may include an encoding circuit coupled to a bus line and a decoder circuit coupled to the bus line. The encoder circuit may receive an input signal and generate an encoded signal on the bus line. The decoder circuit may receive the encoded signal from the bus line and generate the original unencoded signal. The encoder circuit may include a first flip-flop circuit to store a previous input signal from the bus line based on a clocking signal from the bus line. Additionally, the decoder circuit may include a second flip-flop circuit having a clock input to receive the encoded signal from the bus line as a clocking input.

摘要： A single ended current sensed bus with novel static power free receiver circuit is described herein. In one embodiment, a receiver circuit example includes a latch circuit to latch values for a first output and a second output during an evaluation phase in response to an input, a pre-charge circuit coupled to the latch circuit to pre-charge the latch circuit during a pre-charge phase, and a static power dissipation blocking (SPDB) circuit coupled to the pre-charge circuit and the latch circuit to substantially block static power from being dissipated during the pre-charge phase.

摘要： A hierarchical clock distribution system includes a global clock grid that distributes a clock signal to a plurality of regional clock grids. Each of the regional clock grids then distributes the signal to a plurality of corresponding loads. The regional clock grids utilize salphasic clocking techniques to distribute the clock signal to the corresponding loads. The global grid achieves low skew based on the periodicity of the clock signal, rather than the dominance of a standing wave. The electrical distance to termination within the regional clock grids is preferably kept low to avoid the occurrence of phase change regions on the regional grids. In one approach, the regional grids are each driven at multiple points in a symmetrical fashion to reduce the electrical distance to termination.

摘要： A processor includes an input-circuit and a Simon block cipher. The Simon block cipher includes a data transformation circuit, a constant generator, and a key expansion circuit. The data transformation circuit includes logic to shift content of data storage registers. The key expansion circuit includes logic to determine a round key based upon an input symmetric key and data input, a previous round key, and a value from the constant generator. The constant generator includes logic to output a successive one of a list of constants each clock cycle, and to store the outputted constants in storage units. The number of storage units is less than the size of the list of constants.

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.
