摘要： Various embodiments include nested emulation for a source application and source emulator. Duplicate source ISA libraries redirect the source emulator library calls to a target library, thereby forcing the native emulator through proper emulation channels between first and second ISAs. Other embodiments concern accelerating dynamic linking by determining certain function calls that, rather than being processed through emulation of PLT code, are instead directly called without the need for PLT code translation. Some embodiments address both nested emulation and accelerated dynamic linking but other embodiments include one of nested emulation and accelerated dynamic linking. Other embodiments are described herein.

摘要： One embodiment pre-builds translations of kernel functions (KFs) and loads them into a translation pool and corresponding indexed table. The KFs are thus quickly loaded and do not necessarily await trapping and emulation via a LIB emulator. This results in faster access to KFs. Other embodiments provide hybrid emulation where some application functions (e.g., those that need quick performance) are translated from a source ISA library while other applications functions are processed via emulation to a target ISA library. Doing so provides faster access to certain functions. Other embodiments are described herein.

摘要翻译： 一个实施例预先构建内核函数（KF）的翻译，并将它们加载到转换池和相应的索引表中。 因此，KF快速加载，并且不一定等待通过LIB仿真器进行捕获和仿真。 这样可以更快地访问KF。 其他实施例提供混合仿真，其中一些应用功能（例如，需要快速性能的那些）从源ISA库转换，而其他应用功能通过仿真被处理到目标ISA库。 这样做可以更快地访问某些功能。 本文描述了其它实施例。
