Abstract

In mimic architecture devices, programs with equivalent functions are usually implemented on heterogeneous executors. However, due to the differences in the scheduling order of threads among executors, the outputs of programs are also different. Usually, the scheduler in the mimic device needs to compare the outputs of different executors to decide the final output. The difference between the outputs will have a significant impact on the arbitration of the scheduler, causing executor's output cannot pass the arbitration, and the program cannot function normally. In order to solve this problem, some researchers proposed a state synchronization method based on relative time. This method can effectively solve the problem of program state synchronization in multiple heterogeneous executors, but it can be improved in completeness and running efficiency. Based on this method, this paper proposes an improved program synchronization method based on targeted reply, which considers the synchronization problem in more scenarios, saves the communication overhead caused by synchronization, and improves the operation efficiency of the system. The experimental results show that the method is effective to some extent.
