Data stream integrity detection method and device, equipment and medium

The invention relates to a data stream integrity detection method and device, equipment and a medium. The method comprises the steps that a to-be-detected source code input by a user is received, and an original assembly file with line number information is generated; according to a read instruction and a write instruction in the original assembly file, defining the read instruction and the write instruction as an sdDFIx instruction and an ldDFIx instruction by utilizing EUI attributes of preset data; performing code instrumentation on the original assembly file to generate a new assembly file; extending and executing the new instruction set architecture of the new assembly file containing the sdDFIx instruction and the ldDFIx instruction after compiling by utilizing the original instruction set architecture; executing the compiled and linked new assembly file by utilizing the expanded new instruction set architecture to obtain an inspection result of the to-be-inspected code; the invention aims to solve the
