Abstract: A processing unit of a system detects a fault condition associated with the co-processing unit and, upon detection, restores the processing unit using stored user context information. During normal operation, user context information used to execute operation commands are stored by the co-processing unit in memory and maintained after fault detection. A fault condition is detected when at least a portion of the processing unit is rendered non-operational due to a discharging electrostatic event. Fault conditions may be detected by receiving information by the co-processing unit indicative of a fault condition, or by checking at least one memory location associated with processing unit to determine if information stored therein indicates a fault condition. The co-processing unit returns the processing unit to a known, workable state by using the stored user context information to restore the pre-fault detection state information to the memory locations associated with the processing unit.

Abstract translation: 系统的处理单元检测与协处理单元相关联的故障状况，并且在检测时，使用存储的用户上下文信息恢复处理单元。 在正常操作期间，用于执行操作命令的用户上下文信息由协处理单元存储在存储器中并在故障检测之后维护。 当处理单元的至少一部分由于放电静电事件而变得不可操作时，检测到故障状况。 可以通过由协处理单元接收指示故障状况的信息或者通过检查与处理单元相关联的至少一个存储位置来确定其中存储的信息是否指示故障状况来检测故障状况。 协处理单元通过使用存储的用户上下文信息将处理单元返回到已知的可操作状态，以将故障前检测状态信息恢复到与处理单元相关联的存储器位置。
