In an RFID system, a method and apparatus for linking an RFID tag to an associated object. The system includes a relatively simple tag, a reader, a linker, and a store. The reader interrogates the tag for an ID and selectively provides the ID to the linker. The linker, in turn, uses the ID to provide back to the reader an associated Uniform Resource Identifier (“URI”). The reader then forwards the URI to the store. In response, the store returns to the reader the object associated with the ID via the URI. The disclosed method and apparatus provide more efficient and secure tag authentication.

A linker is usually used, in post processing of compiling high-level languages such as C into machine executable language, to bind separately compiled object files and resolve the addresses (142) of global variables (140) declared in the separate files. The invention proposes linking during compile time by using a special purpose hash table called global variables hash table (130) shared among the separate files. This results in a collection of processed object files that are coherent in terms of their addresses (142) for global variables (140) that could be further assembled correctly into machine executable code. This method is useful for compiling separate high level language source files to generate executable machine code employing a technique of address resolution across separate modules.

A device compiler and linker is configured to group instructions into different strands for execution by different threads based on the dependence of those instructions on other, long-latency instructions. A thread may execute a strand that includes long-latency instructions, and then hardware resources previously allocated for the execution of that thread may be de-allocated from the thread and re-allocated to another thread. The other thread may then execute another strand while the long-latency instructions are in flight. With this approach, the other thread is not required to wait for the long-latency instructions to complete before acquiring hardware resources and initiating execution of the other strand, thereby eliminating at least a portion of the time that the other thread would otherwise spend waiting.

Techniques for cloning programming code are disclosed. In an embodiment, the cloned code is in the form of functions in the C language. Further, in a method embodiment, a clone of a function is invoked, and information mapping the clone to the function is generated.

However, if the body function of the clone is accessible by the loader, then the loader allows selection of the body of the clone.

A mechanism for refilling an electronic game board after game elements of different game types, for example those referred to as ‘clickers’ or ‘linkers,’ have been removed through play. In these games, a player must identify a group of matching game elements on a game board, select (or click on) a game element within the group. This causes the group of selecting matching game elements to be removed. A refill process is then executed to replenish the game board with new game elements.

The present invention addresses the latency problem by enabling independent refill at respective computer devices which are engaged in a competitive game. The refill process may also be utilised on a single computer device where a single player is playing a game.
