A novel asymmetric memory partitioning mechanism for providing resolving and reducing memory limitations when an increase in software image size is required. Two partitions are created in non-volatile memory, one smaller than the other. The smaller partition stores a degenerated version of the full-functionality software comprising only essential program code for booting the device and repeating the download and installation procedures until the full-functionality software image is successfully installed in non-volatile memory. The larger portion stores a full-functionality version of the software comprising both essential and non-essential program code. The mechanism also provides the capability of converting devices already deployed in the field. The legacy symmetrical partitioning of the memory in these devices is removed and replaced with asymmetrical partitioning, wherein the smaller partition stores the degenerated software image and the larger partition stores the full-functionality software image.

A method for producing computer processed animation includes a work station composed of a computer and peripheral equipment which produces a graphic movement sequence for a cartoon figure, by compiling a recording of measured data from strategic parts of an actor, and storing in a memory information concerning the figure to be animated. The figure is divided into a plurality of sections which are movable in relation to one another. Prior to figure compilation for producing an image of the figure, the measured data recording for each section is obtained in the form of a space angle. Prior to compiling each section, a grouping of a predetermined number of perspective drawings is stored, in digitized form, in a respective area of the memory, each grouping in a plurality of mutually different space angle positions. A memory area of interest representing a perspective drawing of one of the sections can be addressed with the aid of information relating to the space angle obtained from the measured data recording for the section concerned. The figure is compiled in the compilation image in accordance with a predetermined sequential compilation schedule, section after section, where each subsequent section is added to the nearest proceeding section at a joint location, to build the sections.
