    • Efficient production testing of integrated circuits. A first production test is implemented on a group of integrated circuits and failures among the test group are assessed. Specifically, the results of the first test are analyzed such that integrated circuits having a recoverable fail and integrated circuits having a non-recoverable fail are differentiated. The integrated circuits are integrated based on the analyzed results and a second production test is implemented. The second production test tests the integrated circuits responsive to the segregation, such that the second production test is limited only to integrated circuits with a recoverable fail. The next succeeding production test will then use the new test program in the second production test with the handler bin designated as having integrated circuits not to be re-tested.
    • 集成电路的高效生产测试。 对一组集成电路进行第一次生产测试,并对测试组中的故障进行评估。 具体地,分析第一测试的结果,使得具有可恢复故障的集成电路和具有不可恢复故障的集成电路被区分。 基于分析结果集成了集成电路,实现了第二次生产测试。 第二次生产测试根据分离测试集成电路,使得第二次生产测试仅限于具有可恢复故障的集成电路。 接下来的生产测试将在第二次生产测试中使用新的测试程序,并将处理器箱指定为不具有集成电路的重新测试。

    • Systems and computer program products may provide a virtual system with direct access to one or more sectors of a resource of a computer system. The system and computer program products may include providing, by a computer system to a virtual system, first access control data associated with a regular computer file that corresponds to a resource on the computer system. The system and computer program products may additionally include receiving, at the computer system, a direct read from or direct write to one or more sectors of the resource represented by the regular computer file from the virtual system. The system and computer program products may further include hiding, at the computer system, a hidden computer file from the virtual system. The system and computer program products may additionally include routing, at the computer system, the direct read from or direct write to the hidden computer file on the computer system.
    • 系统和计算机程序产品可以向虚拟系统提供对计算机系统的资源的一个或多个扇区的直接访问。 系统和计算机程序产品可以包括通过计算机系统向虚拟系统提供与对应于计算机系统上的资源的常规计算机文件相关联的第一访问控制数据。 系统和计算机程序产品可以另外包括在计算机系统处从虚拟系统直接读取或直接写入由普通计算机文件表示的资源的一个或多个扇区。 系统和计算机程序产品还可以包括在计算机系统处隐藏来自虚拟系统的隐藏的计算机文件。 系统和计算机程序产品还可以包括在计算机系统处直接读取或直接写入计算机系统上的隐藏的计算机文件的路由。

    • Embodiments relate to granular management of data storage blocks in a data storage system. In one aspect, status values are employed to track “used”, “free”, and “claimed free” storage blocks. A storage block having stored data is identified as used, a storage block available to store data is identified as free, and a storage block having previously stored data removed that has not been reclaimed is identified as claimed free. These values are maintained on a map to track each data block within the data storage system. One or more used blocks are de-allocated, which includes changing the status value of each used block to claimed free Available claimed free data blocks are prioritized for data block allocation over available free data blocks for efficient storage, including enabling efficient reclamation of data blocks and minimizing data movement needed for reclamation-oriented de-fragmentation.
    • 实施例涉及数据存储系统中数据存储块的粒度管理。 在一个方面,使用状态值来跟踪“used”,“free”和“claim free”的存储块。 具有存储数据的存储块被识别为使用,可用于存储数据的存储块被识别为空闲,并且具有未被回收的预先存储的数据被去除的存储块被识别为免费声明。 这些值在地图上维护以跟踪数据存储系统内的每个数据块。 一个或多个使用的块被去分配,其包括将每个使用的块的状态值改变为所要求的空闲可用的所要求的自由数据块优先于用于有效存储的可用空闲数据块的数据块分配,包括实现数据块的有效回收 并尽量减少以填海为导向的拆散所需的数据移动。
