ABSTRACT:
A method and apparatus for the computer-controlled generation of pulses which are arranged in intervals which intervals are grouped in a sequence that is to be repeated. The apparatus employs a preprocessor which supplies, to a revolver processor, data indicating the number and duration of immediately successive identical pulses in each of the intervals forming a sequence as well as data indicating the number of repetitions of the sequence. The first and the last pulse interval within the sequence to be repeated is marked. This data is cycled under clock control in the revolver processor which includes a data input station and a data output station. The clock-controlled cycled data reaching the output station is supplied, by a postprocessor, to a pulse cycle generator for generating the pulses. In response to a tag in the output station marking the start of a sequence to be repeated, the clock-controlled cycle is interrupted, with the data stages being subsequently cyclically addressed under processor control from the first to the last pulse interval in the sequence according to the number of repetitions. The data of each addressed stage is supplied from the output station to the pulse cycle generator. The postprocessor generates from the information of the revolver processor the values for successive pulses forming each interval for controlling the pulse cycle generator.
