Abstract: An op-amp feedback arrangement is used to provide non-skewed clock pulses from a source of skewed clock pulses. Any skew in the clock-in pulses results in a change in the average voltage of a clock-out pulse at the output of the arrangement. The average voltage of the clock-out pulse is compared to a reference voltage to produce a control signal which adjusts the average voltage at the output. Critical transitions in the clock pulses occur at precise time relationships under the control of the control signal.

Abstract: A circuit for rotating a multibit binary word in either the right or the left direction includes a scale factor decoder receiving a scale factor word which specifies the magnitude of the rotation and a direction control signal which specifies the direction of rotation and providing a shift control word which is the same as the scale factor word when a right rotation is specified but providing a shift control word which is the complement of the scale factor word when a left rotation is specified. The circuit also includes a plurality of input buffers receiving an input word and providing corresponding input data, and a one-bit rotator receiving the input data and the direction control signal and rotating the input data in the right direction by one position when a left rotation is specified or providing the input data without rotation when a right rotation is specified.

Abstract: Logic circuits, particularly of the integrated semiconductor type, are accessed at improved speeds by preventing pull-ups from occurring during the access time and by the inclusion of on-chip delay circuitry to avoid switching later stages in a manner to lose information while output nodes of earlier stages are high. All stages are activated in response to a single clock pulse edge.

Abstract: The numbers of gates necessary in an integrated combinatorial logic circuit is reduced by designing the circuit to accept an applied binary word of given length as a plurality of word segments having numbers of bits which add up to the number included in the applied word. A preprocessor responds to the word segments to generate a word characterizing the segments and to apply those words to an arithmetic logic unit designed to add binary words and to generate words having lengths of the applied words.
