METHOD AND SYSTEM FOR ENSURING INTEGRITY OF CRITICAL DATA

摘要

A method and system for ensuring integrity of manipulatable critical data, including a processor configured to execute at least one restartable processing thread module, a shared memory communicatively coupled with the processor and having at least some manipulatable critical data wherein when request to restart the at least one restartable processing thread module is received, the at least one restartable processing thread module is restarted.

1. A method of ensuring integrity of critical data stored in a shared memory, the method comprising:
executing a restartable processing thread that manipulates the critical data; setting a semaphore having an indicator indicative of either a first state, where the restartable processing thread is manipulating the critical data, and a second state, where the restartable processing thread is not manipulating the critical data; and in response to a restart request during the execution of the restartable processing thread, restarting the restartable processing thread when the semaphore is in the second state.
