Timing arrangement for computers

Abstract From the Canadian patent

The invention provides a timing arrangement for a computer for determining timing of a microprogram and for determining starting times of operations performed in real time for example clock interrupt in the program. The arrangement comprises a common clock oscillator which generates timing signals for a control unit of the computer and for real time measuring circuits. A frequency divider is arranged to divide the frequency of the clock oscillator in such a manner that the frequency is adapted to the period length between the operations performed in real time, the frequency of the clock oscillator being an integral multiple of the step pulse frequency intended for the time measuring …
