APPARATUS AND METHOD OF RECORD/REPLAY WITH DYNAMIC REPLACEMENT OF TRAP INSTRUCTION FOR EMBEDDED REAL-TIME SOFTWARE

摘要

Disclosed are a record / replay device and method for embedded real-time software using dynamic replacement insertion of trap instructions. The record / replay device for embedded real time software may include an event recorder configured to record an event history including a time point of occurrence of an event while executing real time software of an embedded system; A code corrector for modifying an instruction code of the real time software based on the recorded event history; And an event reproducing unit executing the modified command code to re-execute the real time software according to the event history.;Embedded Systems, Software Debugging, Record, Replay, Trap Instructions, Dynamic Instruction Replacement
