Abstract: The present invention provide a clock circuit and a method for providing a clock signal. The clock circuit includes: an adaptive clock generation circuit, configured to output an adaptive clock signal; and an adaptive clock driven circuit, configured to be driven by the adaptive clock signal to work. A maximum workable frequency of the adaptive clock driven circuit is higher than or equal to a frequency of the adaptive clock signal. When a working condition of the adaptive clock driven circuit is changed, the maximum workable frequency of the adaptive clock driven circuit is changed, the frequency of the adaptive clock signal which is output by the adaptive clock generation circuit is changed, and a changing direction of the frequency of an adaptive clock signal is consistent with that of the maximum workable frequency. The clock circuit and method may be used in design or manufacturing of a digital circuit.

Abstract: A variable-frequency bus adapter, a variable-frequency bus adapting method and a variable-frequency bus adapting system are provided. The method includes: generating a bus blocking indication according to a dynamic frequency scaling (DFS) request signal sent by a bus side; blocking a current bus transfer according to the bus blocking indication; and feeding back a DFS response signal to the bus side after blocking the current bus transfer, where the DFS response signal is adapted to enable the bus side to perform a DFS operation. In the method, the bus transfer is temporarily blocked during the DFS, so that undesired influence on peripheral components caused by unstable bus block during the bus DFS is reduced without increasing the number of clock domains of the system or modifying the peripheral components, thus reducing the complexity of the implementation of the system, and improving the applicability of dynamic voltage frequency scaling (DVFS).

Abstract: Embodiments of the present disclosure disclose a method for controlling power consumption of an embedded system. The method obtains a data transmission index that is between a bus module and a bus, compares the obtained data transmission index with a preset numeric value range, and adjusts an operation frequency or an operation voltage of the bus module when the data transmission index exceeds the preset numeric value range. Embodiments of the present disclosure further provide a system and a relevant apparatus for controlling power consumption of the embedded system. In comparison with the conventional art, embodiments of the present disclosure effectively monitor the load of the bus module, and adjust the operation parameters of the module according to the monitoring result to enable the module to operate under proper operation parameters and to thereby reduce unnecessary power consumption.
