An embodiment of the present invention discloses a method for quickly responding to a signal, where the method includes: generating a frame synchronization signal; pre-reading image data, and saving the image data after processing the image data; and receiving a TE signal, and outputting the processed image data according to the TE signal. An embodiment of the present invention further discloses an apparatus for quickly responding to a signal. Using the present invention may improve a rate for responding to a signal and reduce an instantaneous bandwidth pressure on a transmission line.

Method and apparatus for quickly responding to signal

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).
