    摘要: 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.

    摘要: 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.

    摘要: 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. In addition, the circuit includes a network receiving data from the one-bit rotator and the shaft control word and rotating the data from the one-bit rotator in only the right direction by a magnitude specified by the shift control word. Furthermore, the circuit includes a plurality of output buffers receiving the data from the network and providing an output word.

    摘要: 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.

The shifting vs. rotating is selected by a binary digital rotate control signal (ROT). The shifting or rotating can be either to the right or to the left, depending upon a binary digital direction control signal (L/R). .Iaddend.
