Classification: CPC G  H | IPC G  H

Claim 14:
15. A processor comprising:
a processor core;
a system clock producing a clock signal based on which the processor core operates;
a multiply-accumulate circuit including a series of ripple counter units comprising:
a first ripple counter unit comprising a ripple counter having a first input coupled to receive a respective target signal, a second input coupled to receive a respective counter reset value, a third input coupled to receive a respective stop count value, and a counter output;
a series of additional ripple counter units comprising a ripple counter having a first input coupled to receive a respective target signal from a respective oscillator, a second input coupled to receive a respective counter reset value, a third input coupled to receive a respective stop count value, and a counter output; and an adder circuit coupled to receive the counter output and a sum from a prior adder circuit output in the series of ripple counter units and produce a sum therefrom at an output; and
wherein the ripple counters are controlled by the respective stop count values to adjust a respective ripple counter sampling period with respect to a reference clock signal to scale the respective counter outputs.
