Abstract: A system including a memory for storing a set of instructions executable by a processor. The instructions being operable to receive a definition of code information, parse the code information and generate a byte code expression for the code information, the generating including resolving the symbols of the code information, wherein the byte code expression relates to only memory access, register access and numerical operations of the code information.

Abstract: A method for emulating one or more file system functions is provided. On a first processing device, a request is received. The request comprises a first data indicating a first file that a file system resident on the first processing device does not support. In an emulation library a second data for emulation of the first file is located. A response based upon the first and second data is formed.

Abstract: A method for creating a second file system on a device implementing a first file system is provided. One or more first files are selected from a set of files. The files comprise one or more characteristics particular to the second file system. One or more ancestors of the first files are selected automatically. The ancestors comprise one or more characteristics particular to the second file system. Based on the first files and the ancestors, data is generated to emulate one or more of the first files and the ancestors (and/or characteristics of one or more of the first files and the ancestors) that the first file system does not support. A file system comprising the first files, ancestors, and the data is generated.

Abstract: In an embodiment according to the present invention, a method for creating a kernel config file is provided. A plurality of selections are entered into a document. Each selection corresponds to one or more components. The document comprises a set of rules for entering the selections and for identifying one or more dependencies of the components. The dependencies are identified based on the set of rules. If an unresolved dependency is found the step of entering is repeated. If no unresolved dependency is found, a kernel configuration file is built based on the document.

Abstract: A method for building an operating system (OS) image is provided comprising the steps of: building a generic directory with common files, the common files being required for a build of a plurality of configurations; building a configuration directory that mirrors the generic directory, the configuration directory including configuration files that correspond to one of the plurality of configurations; and building an image using the configuration files in conjunction with the common files, the image constructed and arranged to operate a device.
