  • Publication number: 20230010386
    Abstract: An input sampling method includes the following: acquiring a first pulse signal and a second pulse signal respectively; widening a pulse width of the first pulse signal to obtain a widened first pulse signal; shielding an invalid signal in the second pulse signal based on the widened first pulse signal to obtain a to-be-sampled signal; and finally, sampling the to-be-sampled signal based on a clock signal. In this way, prior to signal sampling, the invalid signal is shielded to avoid additional power consumption caused by sampling the invalid signal, and at the same time, the pulse width of the signal is widened to avoid sampling failure.

  • Publication number: 20230010338
    Abstract: An input sampling method includes the following operations. A first pulse signal and a second pulse signal are received. Logical operation is performed on the first pulse signal and the second pulse signal to determine a to-be-sampled signal. The to-be-sampled signal is obtained by shielding an invalid part of the second pulse signal according to a logical operation result. Sampling process is performed on the to-be-sampled signal to obtain a target sampled signal.

  • Publication number: 20230005559
    Abstract: A signal generation circuit includes: a clock module, configured to generate a clock signal based on a flag signal; a control module, configured to generate a control signal according to number of transitions of the clock signal within a fixed time; and a generation module, respectively connected to the clock module and the control module, and configured to receive the clock signal, the control signal, and the flag signal, and to generate a target signal. When the flag signal changes from a first level to a second level, the target signal changes from a third level to a fourth level. After being maintained at the fourth level for a target duration, the target signal changes from the fourth level to the third level. The generation module is further configured to determine the target duration according to the clock signal and the control signal.

  • Publication number: 20220358979
    Abstract: A signal processing circuit includes a first signal latch circuit, a second signal latch circuit, and a decoder. The first signal latch circuit receives a command address signal and is driven by an even clock; the second signal latch circuit receives the command address signal and is driven by an odd clock; and the decoder is connected to the first signal latch circuit and the second signal latch circuit, and outputs a control signal. Both the even clock and the odd clock have a frequency equal to that of a reference clock, and both the even clock and the odd clock have a rising edge aligned with a rising edge of the reference clock.
