Embodiment Construction
[0036] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0037] figure 1 is a block diagram of a method for offsetting system disturbances caused by power consumption fluctuations provided by an embodiment of the present invention, as shown in figure 1 As shown, the steps include:
[0038] Step S101: Obtain the power consumption of the subject under test by detecting the power consumption of the subject under test whose performance needs to be improved.
[0039] Wherein, the power consumption of the subject under test can be detected, and in some cases can be equivalent to the load of the subject under test, so the detection of the power consumption of the subject under test can be realized by monitoring the l...

The invention discloses a method and a device for cancelling system disturbance caused by power consumption fluctuation, relating to relevant field of IC design and application of communication manufacture, equipment manufacture, integrated circuit design, and the like. The method comprises the following steps of: obtaining power consumption of a tested main body by detecting the power consumptionof the tested main body acquiring performance improvement; finding a phase adjustment amount corresponding to the power consumption from a load model of the system according to the power consumptionof the tested main body; and compensating the clock phase of the tested main body by using the phase adjustment amount. By dynamic power consumption monitoring and detection as well as feedback inhibition, the embodiment provided by the invention is capable of cancelling the disturbance of the dynamic power consumption to the system so as to reduce system disturbance and suppress noise, thereby improving design stability and system performance.
Description
technical field [0001] The invention relates to IC design and application-related fields such as communication manufacturing, equipment manufacturing, and integrated circuit design, and in particular to a method and device for offsetting system disturbances introduced by power consumption fluctuations. Background technique [0002] As the scale of integrated circuits becomes larger and the system integration becomes higher and higher, the power consumption and heat consumption carried by the unit board area are also increasing. influence is gradually becoming apparent. [0003] Take the Remote Radio Unit in the communication system, RRU, and the error vector magnitude (Error Vector Magnitude, EVM) performance of RRU as an example. The error vector (including the vector of magnitude and phase) is an ideal infinite The vector difference between the error reference signal and the actual transmitted signal, EVM can fully measure the amplitude error and phase error of the modula...
