Abstract

A two-way adaptive clock circuit supporting a wide frequency range is composed of a phase clock generating module, a phase clock selecting module, an adaptive clock stretching or compressing amount regulating circuit module and a control module. The adaptive clock stretching or compressing amount regulating circuit module can monitor delay information of a critical path in a chip in real time and feed the information back into the control module. After receiving a clock stretching or compressing enable signal and a stretching or compressing scale signal, the control module selects a target phase clock from clocks generated by the phase clock generating module to rapidly regulate an adaptive clock in a current cycle. The present invention is applied to an adaptive voltage frequency regulating circuit based on on-line time sequence monitoring.
