A smart card which includes a non-volatile read/write memory, a processor connected to the memory, and an installer module configured to cause the processor to receive computer code having method bodies into the memory, and further configured to cause the processor to perform a method for determining the instruction boundaries of the method bodies and resolving unresolved references within the method bodies. The method includes steps for examining each instruction for a forward jump instruction and a valid ending instruction, maintaining a farthest logical return pointer corresponding to the instruction for which the farthest forward jump instruction or the farthest valid ending instruction is detected, resolving unresolved references within a method body starting with the first instruction and ending with the instruction corresponding to the farthest logical return pointer, and terminating the examination of each instruction within a method body when the instruction under examination is beyond the instruction corresponding to the farthest logical return pointer.

Method and apparatus for linking converted applet files without relocation annotations

A client software program for use on an embedded computing device includes an operating system layer including an abstraction layer, a programming environment, and an application framework including a package manager. The client is configured to interface with a client support server including a package repository, for receiving package data for running a software package on the embedded computing device.

Portable operating environment for information devices

A client software program for use with an embedded device includes an application layer, a programming environment configured to render user interface component areas and query user interface component extensions from a shared delegation object, and an operating system layer. A drawing is preferably split up into a non-overridable system part and an overridable user part. The user interface component data and data used to factorize the way it is rendered are logically separated.

User interface rendering component environment

A graphics rendering software program for use on an embedded computing device includes an application layer, a graphics toolkit, and a graphics driver for rendering a plurality of drawing surfaces, including a first drawing surface and a second drawing surface, on a display of the embedded computing device. The graphics driver is configured to render the first drawing surface at least partially overlapping the second drawing surface on the display. When the first drawing surface is rendered as partially overlapping the second drawing surface, a visible portion of the second drawing surface is computed as a set of rectangular clip segments.

A software program for use on an embedded computing device includes an operating system layer, an application framework, and a programming environment. the programming environment includes a contention locking scheme for setting light object locks, which are handled in user space, and heavy object locks, which are handled at the system level. The contention locking scheme is configured to set a light object lock on an initially unlocked object when a first thread attempts to lock the object, and to maintain a light lock on the object when a nested intra-thread lock is attempted by the first thread.

A smart card which includes a non-volatile read/write memory, a resolve buffer, a processor connected to the memory and the resolve buffer, and an installer module configured to cause the processor to receive computer code having unresolved references into the memory, and further configured to cause the processor to perform a method for resolving unresolved references. The method including steps for copying the contents of the memory into the resolve buffer, detecting unresolved references in the computer code, determining the resolved reference for each of the detected unresolved references, updating the contents of the resolve buffer with the resolved references, and replacing the contents of the memory with the contents of the resolve buffer.
