Abstract

A digital clock throttling device, for gating a clock signal of a circuit, at least includes an accumulator and a gating circuit. The accumulator responsive to a throttling value generates a first output signal. The first output signal is divided into a throttling signal with a most significant bit and a feedback signal with rest bits of the first output signal except for the most significant bit. The feedback signal is sent to the accumulator back for accumulating to the throttling value as the first output signal. The gating circuit coupling with the accumulator responsive to the throttling signal and clock signal gates out some clock cycles of the clock signal, thereby providing a gated clock signal in an adjusted frequency.
