Abstract

See full text

A multi-marker, multi-destination timing signal generator including a count-setting memory for storing a plurality of pulse-count values in a numerical order and a pulse counter for counting the number of pulses from a master clock. An output selection memory stores, for each pulse count value, enabling signals for a plurality of output elements so that a marker signal generated when the pulse counter equals a pulse-counter value in memory may be selectively routed to one or more output elements. The addresses of the count-setting memory and the output selection memory are maintained by an address counter. When the value of the pulse counter equals a pulse-count value stored in the count-setting memory, the address counter counts to the next address value for locating successive values in the count-settiong memory and the output selection memory.
