    • The present invention is a time vernier providing fine timing control of an input signal having coarse timing edges. The time vernier comprises a receiving means for receiving a value representing a desired time delay to be added to the coarse timing edge input. The desired time delay may have both fine and coarse delay aspects. The time vernier also comprises a first decoding means for decoding the fine delay aspect and generating fine delay control signals, as well as a second decoding means for decoding a coarse delay aspect and generating coarse delay control signals. A delay line is also included in the time vernier which has inputs to receive the input signal having coarse timing edges, the fine and coarse delay control signals, and a control voltage which automatically adjusts with temperature and power supply variations, so as to provide for temperature and power supply compensation. The delay line combines the fine and coarse delay signals to provide an output signal with fine timing edges. Furthermore, the architecture of the present invention enables an automated method of calibration in order to adjust fine and coarse delay elements for fabrication process variations and photolithography variations.

    • A crossbar routing arrangement is disclosed for use in a digital system having three or more buses. An associated method is also disclosed. The routing arrangement is configured for transferring a set of data received from any particular one of the buses to any other selected one of the buses and includes a control arrangement associated with each bus for dividing the set of data into at least first and second subsets of data and for adding self-routing signals to each data subset which signals identify the selected bus. A switching arrangement is configured for directing the first and second data subsets in a predetermined way responsive to the self-routing signals. The control arrangement cooperates with the switching arrangement to transfer the data subsets over physically distinct data transfer paths defined between the switching arrangement and the control arrangements. In accordance with one feature, the configuration of the routing arrangement provides for linear expansion whereby to service buses having increased width and/or to service an increased number of buses in a cost effective manner while, in either instance, maintaining high data throughput.

    • A system and method is provided for controlling a brushless DC motor (100), the motor being of the type having a plurality of coils (25, 26, 27) and a switching amplifier coil driving circuit (25A, 26A, 27A) including a plurality of transistors (21, 22, 29, 30, 33, 34). Current application to the plurality of transistors is controlled to obtain, near a commutation point of the motor, a simultaneous rise in current applied to a first of the transistors and a fall in current applied to a second of the transistors. Controlling application of current to the plurality of transistors involves, for each of the transistors, generating a PWM gate drive signal by selectively switching between a nominal PWM signal and a constant signal. The selective switching is in response to a synthesized state signal, the synthesized state signal being generated to alternate variably between the two states in accordance with a desired ramping of current to the first and second transistors. In one embodiment, the control system is employed for a motor used to rotate a reel of a helical scan tape drive.

    • The present invention is directed to a delay line for providing fine timing adjustment on subsequent edges of an input signal. The delay line comprises a plurality of delay elements for fine tuning the position in time of the timing edges of the input signal. Each delay element has a data input and data output where the data output is connected to the subsequent delay element's data input, thereby forming a delay line with delay elements connected in series. This implementation facilitates the addition of fine increments of delay to be added to the input signal and thereby enable fine tuning of timing edges. Also, included is a wired-OR multiplexor having data inputs connected to the data outputs of the plurality of the delay elements and a control input to select a particular data output to thereby provide an output signal having delayed timing edges.
