ABSTRACT:
A time accumulator is adjustable to provide sufficient calculation time regardless of the clock frequency. The time accumulator includes a first register storing a current time and a second register storing a time increment value corresponding to a multiplier multiplied by an original time increment associated with a clock pulse of a clock signal. The clock signal is divided into computation intervals, in which each computation interval includes a predetermined number of clock pulses equivalent to the value of the multiplier. The time accumulator further includes a summation node for adding the current time to the time value to produce an updated current time each computation interval.
