  • Patent number: 9697120
    Abstract: Embodiments of techniques and systems for execution of code with multiple page tables are described. In embodiments, a heterogenous system utilizing multiple processors may use multiple page tables to selectively execute appropriate ones of different versions of executable code. The system may be configured to support use of function pointers to virtual memory addresses. In embodiments, a virtual memory address may be mapped, such as during a code fetch. In embodiments, when a processor seeks to perform a code fetch using the function pointer, a page table associated with the processor may be used to translate the virtual memory address to a physical memory address where code executable by the processor may be found. Usage of multiple page tables may allow the system to support function pointers while utilizing only one virtual memory address for each function that is pointed to. Other embodiments may be described and claimed.

  • Patent number: 9588746
    Abstract: A compiler includes a vector instruction processing mechanism that generates instructions for vector instructions in a way that assures correct operation in a bi-endian environment, wherein the processor architecture contains instructions with an inherent endian bias. The compiler uses a code generation endian preference that is specified by the user, and that determines a natural element order. When the compiler processes a computer program, it generates instructions for vector operations by determining whether the vector instruction has an endian bias that matches the specified endian preference (i.e., the inherent element order of the vector instruction matches the natural element order). When the vector instruction has no endian bias, or when the endian bias of the vector instruction matches the specified endian preference, the compiler generates one or more instructions for the vector instruction as it normally does.

  • Patent number: 9529610
    Abstract: Systems and methods for executing non-native instructions in a computing system having a processor configured to execute native instructions are provided. A dynamic translator uses instruction code translation in parallel with just-in-time (JIT) compilation to execute the non-native instructions. Non-native instructions may be interpreted to generate instruction codes, which may be stored in a shadow memory. During a subsequent scheduling of a non-native instruction for execution, the corresponding instruction code may be retrieved from the shadow memory and executed, thereby avoiding reinterpreting the non-native instruction. In addition, the JIT compiler may compile instruction codes to generate native instructions, which may be made available for execution, further speeding up the execution process.
