Reset device and method, clock system and electronic equipment

Abstract

The invention discloses a reset device and method, a clock system and electronic equipment, and relates to the field of clock design. The reset device comprises a clock generation circuit, the outputend of the clock generation circuit is connected with the input end of a clock signal, the clock generation circuit is used for obtaining an asynchronous reset signal when it is detected that the system clock circuit does not output a first clock signal, the asynchronous reset signal is used for executing reset operation on the asynchronous reset time sequence circuit, and the first clock signal is used for executing reset operation on the synchronous reset circuit; and a second clock signal is generated according to the asynchronous reset signal, wherein the second clock signal is used for executing reset operation on the synchronous reset circuit. Therefore, when the system does not output the first clock signal to reset the synchronous reset circuit, the clock generation circuit can generate the second clock signal used for executing the reset operation on the synchronous reset circuit according to the asynchronous reset signal, and the situation that the synchronous reset circuit cannot be reset when the synchronous reset circuit does not receive the first clock signal is avoided.

Description

technical field [0001] The present application relates to the field of clock design, and more specifically, to a reset device, method, clock system and electronic equipment. Background technique [0002] The current system-on-chip or other large-scale integrated circuits will include processors, buses, and other electronic components. Since different electronic components may use different sequential circuits, the system-on-chip or other large-scale integrated circuits may There will be an asynchronous reset sequence circuit and a synchronous reset sequence circuit at the same time, which puts forward new requirements for clock design.
