Embodiment Construction

[0035] The present invention is described below based on examples, but the present invention is not limited to these examples. In the following detailed description of the invention, some specific details are set forth in detail. The present invention can be fully understood by those skilled in the art without the description of these detailed parts. In order to avoid obscuring the essence of the present invention, well-known methods, procedures, and flow charts are not described in detail. Additionally, the drawings are not necessarily drawn to scale.

[0036] Figure 1a shows a schematic diagram of a digital circuit containing glitch generation, Figure 1b A schematic diagram of a digital circuit containing a propagating glitch is shown.

[0037] According to the order in which glitches are generated in digital circuits, they can be divided into generated glitches and propagating glitches. The AND gate includes a first input terminal A, a second input terminal B and an o...

Abstract

The invention discloses a digital processing circuit, comprising a logic unit comprising at least one combinational logic device, the combinational logic device comprising at least one input end; and the filtering unit is used for dividing the waveform of the received initial input signal into at least two sections of waveforms in one period of the clock signal of the combinational logic device and preventing burrs contained in at least one section of waveform from spreading backwards so as to provide a filtered input signal to the input end of the combinational logic device. According to the invention, the filtering unit prevents the burrs contained in at least one waveform in the initial input signal from spreading backwards, and can eliminate the influence of the burrs in the signal on the power consumption of the whole circuit in time, thereby effectively reducing the extra power consumption caused by the burrs.

Description

technical field [0001] This application relates to the technical field of integrated circuit design, and more particularly to digital processing circuits. Background technique [0002] With the continuous development of power electronics technology, people have higher and higher requirements for the performance of electronic equipment. Among them, power consumption is one of the main factors hindering the development of electronic equipment. [0003] Power consumption in digital processing circuits is mainly divided into dynamic power consumption and static power consumption. The static power consumption generally comes from the leakage current of the CMOS device itself, which accounts for a small proportion in the power consumption of the digital processing circuit. Dynamic power consumption is mainly due to the change of state in each combinational logic device in the circuit. Part of the change of state is to implement a logic function, and part of it is due to false t...
