2.產 品 詳 情 資 料：
WOODWARD 5464-836在這種情況下，處理器單元的總狀態定義為處理器單元的內部狀態，即處理器寄存器的內容加上數據存儲器的內容。每次主單元通過回滾點時，備份單元的狀態都會更新，如果主單元因錯誤而失敗，則備份單元可以從上次通過的回滾點恢復程序執行。為了最大限度地減少更新中涉及的信息量，備份單元僅更新自最新回滾點以來發生的更改。WOODWARD 5464-836在回滾點之間，寫入數據存儲器的這些更改存儲在備份單元的日志緩沖區中。在回滾點，處理器的總寄存器內容也會寫入數據存儲器，因此也會記錄這些信息。一旦建立了回滾點，記錄的寫入操作將傳輸到備份單元的數據存儲器。如果主單元因錯誤而失敗，備份單元將從最后一個回滾點恢復執行，這意味著備份單元將部分重新執行最后一個執行單元。為了在不影響外圍單元（CEX總線上的通信單元）的情況下重新執行執行單元的一部分，還將在回滾點之間記錄外圍單元的引用WOODWARD 5464-836
In this context, the processor unit's total status is defined as the processor unit's internal status, that is, the contents of the processor registers, plus the contents of the data memory. The backup unit's status is updated each time the primary unit passes a rollback point, enabling the backup unit to resume program execution from the last rollback point passed, should the primary unit fail due to error. In order to minimize the amount of information involved in the update, the backup unit is updated only with the changes taking place since the latest rollback point. Between rollback points, these changes that writes in the data memory, WOODWARD 5464-836are stored in a log buffer in the backup unit. At a rollback point, the processor's total register contents are also written into the data memory, so that this information is also logged. Once the rollback point is established, the logged write operations are transferred to the backup unit's data memory If the primary unit fails because of an error, the backup unit resumes execution from the last rollback point, which means the last execution unit is partially re-executed by the backup unit. In order to re-execute a portion of the execution unit without affecting the peripheral units (communication units on the CEX-Bus), the peripheral units' references are also logged between rollback pointsWOODWARD 5464-836
