A frequency and timing generator is presented with high accuracy and frequency resolution and no switching time between different timing cycles for a wide applicable frequency range, wherein the repetition rate of the timing cycles is not limited by the processing speed of the components. The frequency and timing generator according to the invention is accomplished by an apparatus for parallel processing of a series of timing signals comprising at least one processing unit for processing and calculating time values from timing parameters representing the series of timing signals, an output unit for outputting the series of timing signals, and an input unit for inputting the timing parameters. The sequences of n successive timing parameters to be parallelly processed are distributable by the input unit to n processing units. A first time value from a first one of the timing parameters is calculatable by a first one of the processing units, and a succesive time value is calculatable by a succesive one of the processing units from the corresponding successive timing parameter of the sequence and the calculated time value of the respective preceding timing parameter.
