The invention relates to an eye pattern quality optimization method and device, electronic equipment and a storage medium. The eye pattern quality optimization method includes: enabling aprocessor to send a detection instruction to a memory; acquiring a duty ratio detection result sent by the memory; and adjusting the synchronizing signal according to the duty ratio detection result until the duty ratio detection result returned by the memory is within a preset duty ratio range, wherein the detection instruction is used for indicating the memory to carry out duty ratio detection on a synchronization signal sent by the processor, the duty ratio of the synchronization signal is related to the eye pattern distortion degree of the data signal sent to the memory by the processor, when the duty ratio detection result is within a preset duty ratio range, the eye pattern distortion degree of the data signal is smaller than a preset threshold. By adopting the method, the eye pattern quality of the data signal can be improved, and normal data communication between the processor and the memory is ensured.
Description
technical field [0001] The present application relates to the technical field of signal processing, in particular to an eye pattern quality optimization method, device, electronic equipment and storage medium. Background technique [0002] In electronic devices such as mobile phones, Dynamic Random Access Memory (Dynamic Random Access Memory, DRAM for short) can interact with a central processing unit (Central Processing Unit, CPU for short) to complete reading and writing of high-speed digital signals. The CPU can generate the eye diagram of the digital signal, and evaluate the quality of the digital signal transmitted between the CPU and the DRAM according to the quality of the eye diagram, so as to adjust the signal parameters in time according to the quality of the eye diagram. Wherein, the above-mentioned eye diagram is formed by superimposing each symbol waveform obtained by scanning the signal, which resembles an image of an eye. [0003] In the traditional method, t...
