摘要： A clocking mechanism is provided for multiple overlapped dynamic programmable logic arrays which are used in a digital control unit wherein a sequence of control words are used to produce successive groups of control point signals. Such a control unit includes a plurality of dynamic programmable logic arrays for individually producing different ones of the control words. Each such control word includes a strobe field which is coded to identify a programmable logic array other than the one which produced it. The control unit also includes control circuitry responsive to the control words for producing the control point signals for successive machine control cycles. The control circuitry includes circuitry responsive to the strobe field in each control word for producing a strobe signal for selecting the next programmable logic array to supply a control word to the control circuitry. This control unit further includes clocking circuitry resposive to the strobe signals produced by the control circuitry for producing clocking signals for the dynamic programmable logic arrays. Such clocking circuitry includes only combinatorial logic circuitry for producing the clocking signals.

摘要： A logic performing cell for use in array structures is provided which allows greater density fabrication in integrated circuits and reduces operational delays. The array has a plurality of output lines intercepted by a plurality of orthogonally oriented input lines, with elements in the form of a three terminal device located at each of the intersections of the input and output lines so that logical functions are performed on interrogation signals placed on the input lines and the responses thereto placed on the output lines. The three terminal device transfer gates are connected in groups of series strings which are connected in parallel to a recombination line. These groups of series connected transfer gates comprise a programmed mix of enhancement and depletion devices. Each logic function of each group of transfer gates establishes an output which, when coupled to the recombining output circuit line, provides an overall logic function for the logic performing cell.

摘要： A digital data signal transfer mechanism is provided for use in large scale integration digital data processor circuitry formed on an integrated circuit chip. The signal transfer mechanism includes a plural-bit data bus formed on the integrated circuit chip for transferring plural-bit binary data signals between different locations on the chip. The signal transfer mechanism also includes plural-bit signal source circuitry and plural-bit signal destination circuitry formed on the integrated circuit chip and coupled to the plural-bit data bus for respectively supplying plural-bit data signals to and receiving plural-bit data signals from the bus. The signal transfer mechanism further includes processor control circuitry coupled to the signal source and signal destination circuitry for enabling the signal source circuitry to put a plural-bit data signal onto the data bus during a first processor control cycle and for enabling the signal destination circuitry to take in this plural-bit data signal from the bus during a second and different processor control cycle. The inherent capacitance of the plural-bit data bus serves to store the plural-bit data signal during the first and second and any intervening processor control cycles.

摘要： A clocking system for complex electronic devices is created in an hierarchial manner whereby the master clock pulse is provided to a plurality of digital pulse aligners which in turn provide phase aligned clock signals at the field replaceable unit level to either a slave clock or a digital phase aligner. The slave clock or the digital phase aligner at the field replaceable unit level in turn provides an aligned clock pulse to a timing node on respective chips. A third level of the hierarchy provides similarly aligned pulses to individual using-circuits on the chips of the system. The digital phase aligner, aligning the output pulse at the timing node of the next level with the reference pulses being provided to the digital phase aligner at each level, insures that the timing pulses arriving at the utilizing circuits are synchronously aligned with clock pulses of the master clock. The system provides dramatic simplification of replacement of either field replaceable units or individual components within field replaceable units. The system is self-phasing and self-correcting to accommodate timing misalignments caused by any variations in the timing delays at all levels, thereby reducing the jitter that must be accommodated.

摘要： Improved tristate control circuitry is provided for a driver circuit formed on an integrated circuit chip. A parallel-connected combination of a depletion mode transistor and an enhancement mode transistor is connected in series in the voltage supply path for the driver circuit for controlling whether the driver circuit is in an active mode or a standby mode by controlling the supplying of operating voltage thereto. A further enhancement mode transistor provides a shunting action between the driver circuit side of the parallel-connected transistors and circuit ground to further aid in the control of the driver circuit operating mode.

摘要： A dual path ring oscillator core includes three dual path inverters, each having a first inverter and a second inverter. Within the first inverter, one transistor is coupled to a first output of a previous dual path inverter, while another transistor is coupled to a second output of the previous dual path inverter. Within the second inverter, one transistor is coupled to the second output of the previous dual path inverter, while another transistor is coupled to the previous dual path inverter's first output. A first and a final dual path inverter are analogously coupled. A transient pulse will not propagate through successive dual path inverter stages. A dual to single path converter is coupled to receive signals output by the final dual path inverter. If a transient signal appears at a dual to single path converter input, stray output node capacitance maintains a correct output signal value.
