The invention relates to a signal decoding system, comprising a plurality of electronic devices, a signal collection unit and a decoding unit; wherein the decoding unit comprises a segmentation module and a decoding module; the signal collection module collects signals transmitted by the electronic devices, which are a data wave and a clock wave and transmits the data wave and the clock wave to the segmentation module; the segmentation module respectively determines the starting position and the end position of each section of data wave and clock wave; sectional division is carried out on the signal waves collected by a signal collection unit; the decoding module facilitates clock bits segmented after the start positions of the segmented clock waves to correspond to the data bits of the data waves under the same horizontal coordinate and compares the ordinate value of data bits with the preset value to determine codes of the data bits. The invention further provides a signal decoding method. In the invention, the segmentation module and the decoding module of the decoding unit automatically carry out signal segmentation and decoding, thus being capable of automatically decoding signal waveforms collected by relevant instruments and improving accuracy and efficiency of signal decoding.
Description
technical field [0001] The invention relates to a signal decoding system and a decoding method thereof. Background technique [0002] In the master-slave integrated circuit, the sending end sends signals to the receiving end through the bus. To further analyze the signals at the sending end or the receiving end, it is necessary to first collect and then decode the signals at the sending end or the receiving end. At present, instruments such as oscilloscopes or logic analyzers are used to collect signals, and the collected signals are displayed in waveforms, and then inspectors observe the relevant information displayed in the waveforms to decode, and then further analyze the decoded signals. [0003] The above-mentioned manual decoding method takes a lot of time and effort, is extremely error-prone, and cannot perform a large number of samples in a short period of time, so the accuracy and efficiency of the manual decoding method will be extremely low.
