摘要： Approaches for dispatching routines in an emulated operating system. A method includes executing a first operating system (OS) on an instruction processor of a data processing system. The first OS includes instructions of a first instruction set that are native to the instruction processor. A second OS is emulated on the first OS and includes instructions of a second instruction set that are not native to the instruction processor. A first plurality of tasks is created by the emulated second OS. The first OS individually schedules the first plurality of tasks and dispatches the first plurality of emulated tasks for emulation according to the scheduling.

摘要： Approaches for emulating an operating system. A method includes executing a first operating system (OS) on an instruction processor. The first OS includes instructions of a first instruction set that are native to the instruction processor. A second OS is emulated on the first OS and includes instructions of a second instruction set that are not native to the instruction processor. An emulated transfer-of-control instruction is determined during emulation of the second OS to target either instructions of the first set or the second set. In response to determining that instructions of the first set are targeted, control is transferred to the targeted instructions of the first set on the instruction processor. In response to determining that instructions of the second set are targeted, the targeted instructions of the second set are retrieved and emulated.

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 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： 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： A method for obtaining access to database files in a computing system includes receiving, at an operating system, a first call from a database management system requesting access to a database file; creating, by the operating system, a data expanse file; and allowing the database management system to request views of data in the data expanse file by using an instruction processor and a view instruction. A computer program product may include a non-transitory computer-readable medium comprising instructions which, when executed by a processor of a computing system, cause the processor to perform the following actions: receiving, at an operating system, a first call from a database management system requesting access to a database file; creating, by the operating system, a data expanse file; and allowing the database management system to request views of data in the data expanse file by using an instruction processor and a view instruction.
