Abstract

Methods, systems, and computer program products are provided for machine-specific instruction set translation. One example method includes identifying computing devices, each device having a respective software component installed, the software component including a translator component for translating a program in a portable format to a machine-specific instruction set, and a sandbox component for executing programs translated to the machine-specific instruction set on the computing device using software-based fault isolation; identifying computing devices having a given hardware configuration; and transmitting another translator component and another sandbox component to each of the identified computing devices. Each of the identified computing devices having the given hardware configuration is configured to receive the components and to configure its software component to use the received components in lieu of the corresponding components.

Claims19

Dependent claims

A non-transitory computer-readable medium having instructions stored thereon that, when executed on a computing device having a machine-specific instruction set, cause the computing device to perform operations comprising:

receiving, by the computing device and from a computing system that is remotely located from the computing device, first portable code, the first portable code being a portable version of a first program,
wherein the computing device includes multiple sets of application environment components and each set of application environment components includes:
(i) a respective translator component for translating portable code into the machine-specific instruction set of the computing device, and
(ii) a respective sandboxing component for executing translated programs that have been translated into the machine-specific instruction set of the computing device by one of the translator components, the respective sandboxing component using software-based fault isolation;
selecting, based on a set of selection criteria and from among the multiple sets of application environment components, a particular set of application environment components;
translating the first portable code into the machine-specific instruction set of the computing device using the respective translator component of the particular set of application environment components to generate a machine-specific version of the first program;
and
executing the machine-specific version of the first program on the computing device using the respective sandboxing component of the particular set of application environment components.
