要約(日本語)：In recent years, High Performance Computers have been increasingly adopted in automotive systems to realize Autonomous Driving and Advanced Driver Assistance Systems. The use of multi-core processors has become standard in HPC, raising the critical issue of implementing mutual exclusion among cores. In tightly coupled multi-core systems, mutual exclusion is typically achieved using special instructions provided by microprocessors, known as atomic instructions.However, these methods face challenges such as lack of compatibility and real-time performance issues. Therefore, we propose a timestamp-based mutual exclusion method that aligns the order of lock requests with the order of lock acquisition, without relying on special atomic instructions provided by the processor.
