Patent number: 11422943Abstract: One embodiment provides a device. The device includes a processor; a memory; and translator logic. The processor is to execute a host instruction set. The translator logic is to determine whether an offset is a constant and whether the offset is greater than zero and less than a maximum offset in response to receiving a guest memory access instruction that contains a base address plus or minus the offset, the maximum offset related to at least one of a host instruction set architecture (ISA) and a guest ISA.Type: GrantFiled: March 27, 2015Date of Patent: August 23, 2022Assignee: Intel CorporationInventors: Jianhui Li, Yong Wu, Yihua Jin, Xueliang Zhong, Xiao Lin

Patent number: 10761867Abstract: 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.Type: GrantFiled: December 15, 2017Date of Patent: September 1, 2020Assignee: Intel CorporationInventors: Xueliang Zhong, Jianhui Li, Jian Ping Chen, Tingtao Li, Yong Wu, Wen Tan, Xiao Dong Lin

Patent number: 9928067Abstract: Systems and methods are provided in example embodiments for performing binary translation. A binary translation system converts, by a translator module, source instructions to target instructions. The binary translation system identifies a condition code block in the source instructions, where the condition code block includes a plurality of condition bits. In response to identifying the condition code block, the binary translation system provides an optimizer module to convert the condition code block. Then, the binary translation system performs a pre-execution on the condition code block to resolve the plurality of condition bits in the condition code block.Type: GrantFiled: September 21, 2012Date of Patent: March 27, 2018Assignee: Intel CorporationInventors: Xueliang Zhong, Jianhui Li, Jian Ping Jane Chen, Gang Wang, Yi Qian, Huifeng Gu

Patent number: 9910721Abstract: Methods, apparatuses and storage medium associated with execution of application code having multiple ISAs, are disclosed. In various embodiments, a runtime environment may execute application code having multiple instruction set architectures. The runtime environment may be configured to execute first code of the application code according to a first instruction set architecture, while also configured to execute second code of the application code according to a second instruction set architecture that extends the first instruction set architecture. Using gates, the runtime environment may be adapted to adapt an interaction from the first code to the second instruction set architecture and/or adapt an interaction from the second code to the first instruction set architecture and, subsequently, return to executing the application code according to the first instruction set architecture or the second instruction set architecture, respectively. Other embodiments may be disclosed or claimed.Type: GrantFiled: December 9, 2014Date of Patent: March 6, 2018Assignee: Intel CorporationInventors: Yong Wu, Xiao Dong Lin, Yihua Jin, Xueliang Zhong, Jianhui Li
