    • Described is method and apparatus for handling exception signals in combination particularly with the dynamic conversion of binary code executable by a one computing platform into binary code executed instead by another computing platform. An exception handling unit selectively handles some exception signals with respect to a target state and handles others with respect to a subject state derived from the target state. Signal handling sub-units are arranged to process the exception signal with respect to the target state and output a request either to return to execution or to pass on the exception signal. A delivery path selection unit is arranged to determine a delivery path of the exception signal to a selected group of the plurality of signal handling sub-units. A signal control unit is arranged to deliver the exception signal in turn to each of the selected group of signal handling sub-units.
    • 描述了用于处理异常信号的方法和装置,特别是与由一个计算平台执行的二进制代码的动态转换组合成由另一个计算平台执行的二进制代码组合。 异常处理单元选择性地处理关于目标状态的一些异常信号,并处理关于从目标状态导出的对象状态的其他信号。 信号处理子单元被布置为处理关于目标状态的异常信号,并输出请求返回执行或传递异常信号。 传送路径选择单元被布置为确定异常信号到多个信号处理子单元中所选择的组的传送路径。 信号控制单元被布置成将异常信号依次传送到所选择的一组信号处理子单元中的每一个。

    • A partitioning technique utilized by a translator to divide the subject code space into regions, referred to hereafter as partitions, where each partition contains a distinct set of basic blocks of subject code and corresponding target code. The partitioning technique divides the translator's representation of subject code and subject code translations into non-overlapping regions of subject memory. In this manner, when the subject program modifies subject code, only those partitions actually affected by the self-modifying code need be discarded and all translations in unaffected partitions can be kept. This partitioning technique is advantageous in limiting the amount of target code that must be retranslated in response to self-modifying code operation. In another process, the partitioning technique allows multithreaded subject programs that also involve self-modifying code to perform code modification in a thread-safe manner.
    • 翻译器使用的分割技术将主题代码空间划分为以下称为分区的区域,其中每个分区包含主题代码的基本块和相应的目标代码的不同集合。 分割技术将翻译者的主题代码和主题代码翻译的表示分为主题记忆的非重叠区域。 以这种方式,当主体程序修改主题代码时,仅需要丢弃实际受自修改代码影响的分区,并且可以保留未受影响的分区中的所有翻译。 这种分割技术有利于限制响应于自修改代码操作必须重新翻译的目标代码的量。 在另一个过程中,分区技术允许包含自修改代码的多线程主题程序以线程安全的方式执行代码修改。

    • The system supports special needs customer at an airport. A controller processes request, flight and personnel data, generates assignments, and distributes messages. Workstations register available personnel, import/export customer requests and flight information, edit additional customer and flight data, and authorize or overwrite dispatch decisions. Handheld devices provide customer registration, service recording and location registration, and communicate service instructions and activity planning. The controller receives and analyzes data based upon a set of conditions that determine the status of any service request, the location where service is needed, the type of assistance needed, its priority, and the destination of the service. Upon arrival at the destination, or, based upon a set of predetermined conditions, the controller analyzes current conditions, determines the next set of requests and assignments, and provides information needed to support the next assignments. In an emergency, the controller prioritizes the emergency, and reports the emergency to dispatchers.
    • 该系统支持机场的特殊需求客户。 控制器处理请求,飞行和人员数据,生成分配和分发消息。 工作站注册可用人员,导入/导出客户请求和航班信息,编辑其他客户和航班数据,以及授权或覆盖调度决策。 手持设备提供客户注册,服务记录和位置注册,并传达服务说明和活动计划。 控制器基于确定任何服务请求的状态,需要服务的位置,所需的帮助类型,其优先级和服务的目的地的一组条件来接收和分析数据。 在到达目的地时,或者基于一组预定条件,控制器分析当前条件,确定下一组请求和分配,并提供支持下一个分配所需的信息。 在紧急情况下,控制员将紧急事件排在首位,并向调度员报告紧急情况。
