摘要： A computing system and method of executing a software program and translation of instructions for an emulated computing environment. The computing system includes a programmable circuit capable of executing native instructions of a first instruction set architecture and incapable of executing non-native instructions of a second instruction set architecture. The emulator operates within an interface layer and translates non-native applications hosted within an emulated operating system for execution. The computing system includes translated memory banks defined at least in part by the emulated operating system and capable of native execution on the programmable circuit, where the emulated operating system is incapable of execution on the programmable circuit. The computing system includes a linker configured to manage association of at least one of the one or more translated memory banks to the interface layer for native execution by the programmable circuit in place of a corresponding bank of non-native instructions.

摘要： Systems and methods for testing and validation of translated memory banks used in an emulated system are disclosed. One method includes translating one or more banks of non-native instructions into one or more banks of native instructions executable in a computing system having a native instruction set architecture. The one or more banks of non-native instructions define one or more tests of execution of a non-native instruction set architecture. The method also includes loading a memory with instructions and data defined according to the non-native instruction set architecture and addressed by the one or more tests, and triggering, by an emulator, execution of the translated one or more banks of native instructions. The method further includes, upon detection of an error during execution of the translated one or more banks of native instructions, identifying an error in execution of the non-native instruction set architecture by the computing system.

摘要： A memory management interface is provided to synchronize the operation of two disparate operating systems (OSes) that are executing on the same data processing platform. In one embodiment, the first operating system is a legacy OS of the type that is generally associated with an enterprise-level data processing system such as a mainframe. In contrast, the second OS is of a type designed to execute on commodity hardware such as personal computers. The first OS communicates with the second OS via a control logic interface to establish its execution environment, and to perform memory management functions. This interface supports a two-phase boot process that ensures that all memory allocated to the first OS can be released if an error occurs that affects operations of the first OS. This prevents the development of memory leaks.
摘要翻译：提供存储器管理接口以同步在同一数据处理平台上执行的两个不同的操作系统（OS）的操作。在一个实施例中，第一操作系统是通常与诸如主机的企业级数据处理系统相关联的类型的旧式OS。相比之下，第二个操作系统是一种设计用于在诸如个人计算机的商品硬件上执行的类型。第一OS通过控制逻辑接口与第二OS通信以建立其执行环境，并执行存储器管理功能。此接口支持两阶段引导过程，确保如果发生影响第一个操作系统的操作的错误，则可以释放分配给第一个操作系统的所有内存。这样可以防止内存泄漏的发展。

摘要： Approaches for recovering state data between boot sessions of an emulated operating system (OS). An OS is emulated on a host OS. In response to each memory acquire request from the emulated OS, an interface to the host OS returns a memory area for use by the emulated OS and stores allocation data associated with the memory area. The allocation data includes an address referencing the memory area and a boot sequence number that indicates a boot session of the emulated OS. While booting the second emulated OS to a current boot session, the stored allocation data is retrieved from the interface, and in response to the stored allocation data including a selected boot sequence number, data from the memory area referenced by the address in the allocation data is stored in retentive storage by the second OS.

摘要： Disclosure of approaches for stabilizing an emulated system. In one approach, a first operating system (OS) is executed on an instruction processor, the first OS including instructions native to the instruction processor. A second OS and a plurality of application programs are emulated on the first OS. The second OS polls the first OS for memory statistics of the first OS. The memory statistics indicate a current state of operating parameters of the memory of the data processing system used by the first OS in managing the data processing system. The second OS controls a number of the application programs allowed to execute in response to the memory statistics provided by the first OS to the second OS.

摘要： A mechanism is disclosed for performing I/O operations using queue banks within a data processing system that supports multiple processing partitions. A queue bank is a re-useable area of memory allocated for performing I/O operations. All memory locking and address-translation functions are generally performed only once for a queue bank to reduce system overhead. After a queue bank has been used to perform an I/O operation, some processing is performed to make it available for re-use. This processing determines whether the queue bank contains memory that is being removed from a current processing partition. If so, a delay is imposed so that the queue bank is not made available for immediate re-use. This creates a window of time wherein all queue banks that contain the affected memory are inactive, thereby allowing the affected memory to be removed from the partition without halting on-going I/O activity.
摘要翻译：公开了一种用于使用支持多个处理分区的数据处理系统内的队列进行I / O操作的机制。队列库是分配用于执行I / O操作的可重用的内存区域。所有内存锁定和地址转换功能通常只对队列执行一次，以减少系统开销。在使用队列执行I / O操作之后，执行一些处理以使其可以重新使用。该处理确定队列库是否包含正在从当前处理分区移除的存储器。如果是这样，则会发生延迟，使得队列不能立即重新使用。这将创建一个时间窗口，其中包含受影响的内存的所有队列都不活动，从而允许从分区中删除受影响的内存，而不会停止正在进行的I / O活动。

摘要： The disclosure relates generally to managing assignment of tasks among instruction processors (IPs) within a computer system having multiple IPs, and more particularly to binding emulated IPs with a host system's IPs (e.g., processor cores) for facilitating control over affinity-based assignment of tasks among the host system's IPs by a task manager (e.g., OS) that is executing on the emulated IPs, rather than running directly on the host system's IPs. Certain embodiments provide techniques for binding emulated IPs with actual IPs of a computing system that is hosting the emulated IPs, thereby enabling better control of management of the system by a task manager executing on the emulated IPs. For instance, in certain embodiments, a dispatcher (e.g., of an OS running on emulated IPs) performs affinity-based management of task assignment for tasks performed for an application program among IPs of a host system that is hosting the emulated IPs.
摘要翻译：本公开一般涉及管理具有多个IP的计算机系统内的指令处理器（IP）中的任务的分配，更具体地说，涉及将仿真IP与主机系统的IP（例如，处理器核）绑定在一起，以便于对基于亲和力的分配进行控制任务管理器（例如OS）在主机系统的IP之间执行任务，而不是直接在主机系统的IP上运行。某些实施例提供了用于将仿真的IP与承载仿真IP的计算系统的实际IP绑定的技术，从而能够更好地控制由仿真IP执行的任务管理器对系统的管理。例如，在某些实施例中，调度员（例如，在仿真IP上运行的OS）对承载仿真IP的主机系统的IP之间的应用程序执行的任务执行基于关系的对任务分配的管理。
