Description
Technical field [0001] The invention relates to data compression storage technology, in particular to a real-time collection and compression storage method of data in a system. The compressed storage method is mainly suitable for the collection and analysis of complex digital information, especially in the investigation of small probability events, and is mainly used in the security field with high reliability requirements. Background technique [0002] With the complexity of electronic systems, communication between systems is essential, especially the extensive use of digital buses. There may be some small-probability failures in the debugging stage, and these failures will bring great troubles to designers and users. In order to locate the small-probability faults quickly and effectively solve the problems, a convenient and reliable recording method is needed to analyze the relevant data and system working conditions at the time of the fault. The traditional troubleshooti...
