【発明の名称】デジタル・イベント発生器
Document Type and Number:
Japanese Patent JPH0666664
Kind Code:
B2
Abstract:
A multiple digital event generator produces events with timing that is programmable, yet the event generator requires a minimum of circuitry for its construction and is capable of operating at very high speeds. A linear feedback shift register is used to produce an arbitrary sequence of non-repeating binary numbers. These numbers are then monitored by one or more digital comparators whose other digital input is chosen so as to cause the desired event to occur when a certain number in the number sequence occurs. The minimum time between events and the maximum range of event control timing is adjustable by varying the frequency of the clock input to the linear feedback shift register. Maximum speed is achieved by using one set of the shift register flip-flop outputs (Q or Q-not) for internal feedback and the other set (Q-not or Q) for the output to the digital comparators, so that the speed of operation of the shift register is not degraded by the load of the multiple digital comparator circuits on its output.
