Controlling an order of instructions executed by a VLIW computing architecture comprised of a plurality of computing functional units. A first VLIW instruction sequence is generated based on jobs selected from a job queue, each instruction field of the VLIWs corresponding to one of the computing functional units and containing a sequential instruction. The first VLIW sequence is sequentially executed by the computing architecture, and a detection is made if any of the computing functional units is in a free state. When at least one free computing functional units is detected, a second sequence of long instruction words is generated including instructions from a selected new job from the job queue for each such free computing functional unit. The second sequence of long instruction words is copied into the first sequence of long instruction words, and execution of the first sequence of long instruction words is resumed if it was halted.

Instruction execution control for very long instruction words computing architecture based on the free state of the computing function units

Executing a plurality of print jobs in a job queue by a computing architecture, each print job including at least one instruction for processing print data, including accessing one of the print jobs from the job queue, determining whether the accessed print job represents an image, selecting a high resolution mode in the case that the accessed print job represents an image, selecting a low resolution mode in the case that the accessed print job does not represent an image, and executing the accessed print job in accordance with the selected resolution mode.

A decrypting compiler that accepts encrypted source code from a software manufacturer, decrypts the encrypted source code into plain text that is not accessible outside the compiler, and compiles the decrypted source code into linkable binary objects. Because the decrypting compiler decrypts the encrypted source code such that the plain text is not accessible outside the compiler, trade secret and proprietary information from the source code is not easily learned by third-party software developers.

The present invention relates to controlling a presentation device coupled to the presentation system using a user interface generated by a computing system, the user interface including one or more regions which vary in size based on whether the user interface is being displayed, the user interface accepting input from a pointing device to control the presentation device.
