Abstract
A means to set spark timing in accordance with engine speed includes a counter to count clock pulses between engine speed reference pulses. A read-only memory has successive memory locations each storing an addend quantity and a repeats number. An adder unit, including an accumulator, operates to access the memory locations, and to add the addend quantities to the contents of the accumulator repeatedly a number of times equal to the respective repeats numbers. A comparator produces an ignition firing pulse when the contents of the accumulator corresponds with the reference period number provided by the counter.
