摘要:
An emulating data processor includes a host system and an emulating processor with outputs to and inputs from the host system. The emulating processor executes sequences of instructions executable by a PC being emulated, but a host processor independently executes sequences of its instructions which are different from PC instructions. Circuitry monitors the emulating processor outputs and provides information to the host system so that it can emulate the environment of the PC CPU, emulating both memory and I/O devices. The memory accesses of the emulating processor are mapped into the host system memory, so that the host processor is protected from defective PC software on the emulating processor. The display updates of the emulating processor are detected and provide information for the host processor in updating a part of its display which provides the information a PC display would provide simultaneously with the display characteristic of the host system. An input/output processor handles I/O operation requests of the emulating processor, using the host system I/O devices to emulate some of the PC I/O devices. Output operations to the printer may go either to a local printer or to a file for subsequent printing, so a buffer which can be unloaded to either destination emulates the PC printer. Floppy operations may be handled either by a floppy disk controller like that of the PC or by a software controller of a file in host rigid disk memory which may be accessed as a PC floppy disk, so that a data structure containing parameters of the operation is loaded and provided to the appropriate controller. Rigid disk operations are handled by another file in host rigid disk memory which may be accessed as a PC rigid disk, and an appropriate I/O operating system routine is provided so that the emulating processor can pass the operation parameters through to the host rigid disk controller in a group of registers. Keyboard input operations may come either from the host keyboard or directly from a data structure managed by the host processor, in each case converted to PC codes, and another buffer which can be loaded from either source emulates the PC keyboard. The host system emulates the environment of the emulating processor while emulating the user interface of the PC.

Bindings are used to describe a document (and a different document) by associating content elements with layout elements, the layout elements defining layout features or placement information to be applied to the associated content elements in the document, the bindings being stored separately from both the content and layout elements.
摘要:
A multiprocessor system comprises concurrent display of video data reflecting the operation of two processors in discrete portions of a single display screen with a user interface adapted for interaction with both processors. One processor controls the entire display while allocating a portion of the display screen for the use of the other processor which processor emulates a target processor system, for example, the IBM PC. A user interface is represented on the display screen in the form of metaphoric objects, called icons, with which the user can interact by changing the input focus to a designated object by visually pointed to it via the input means, which thereafter permits manipulation of the designated object or interaction with data input/output relative to the designated object. This input means is also used to initially change the input focus to either the allocated emulating processor screen portion or to the remaining portion of the central processor display screen prior to interaction with the metaphoric objects in a selected screen portion, the change of the input focus causing subsequent user input via the input means to be directed to the selected screen portion until interrupted by a change in focus input to the other of the screen portions by the user via the input means. An icon may be a representation of a virtual object, such as a virtual floppy disk, that is accessible in either the host system world or in the emulating processor world even through the virtual floppy disk may have a filing system alien to the host system world.

摘要:
Apparatus and methods of revealing the hierarchical structure of a document having content of a characteristic type of content are described. The hierarchical structure may be expressed, independently of document content type, as a tree structure of one or more nodes. A semantic representation for interpreting the tree structure may also be provided. Document description files are used to encapsulate structural and meta information associated with a document stored on a computer-readable medium. Document description files are external to native application files and have a set of required fields. Document description files point to the referenced document data using Uniform Resource Locators (URLs) and serve as virtual documents. In addition to the required fields, applications can choose to encode additional structural information in the document description files.

Computer-implemented methods, program products and data structures for tagging data assets are disclosed. An interface which can receive location information to identify a storage location identifier for a data asset to be saved is presented to a user. The location information for the data asset to be saved and a selection identifying a concept and a relation between the concept and the data asset to be saved are received from the user through the interface. The asset reference for the data asset to be saved is stored in a tag database and an association is created in the tag database representing the relation between the data asset to be saved and the identified concept.

An icon may be a representation of a virtual object, such as a virtual floppy disk, that is accessible in either the host system world or in the emulating processor world even though the virtual floppy disk may have a filing system alien to the host system world. Facilities are also provided to permit transferring of displayed data reflecting the operation of one processor to the control of the other processor in response to user inputs selecting the data to be transferred and indicating the destination of the selected data on the display. More specifically, if data from each processor is displayed in a discrete portion of the display screen, the user may select data in one processor's controlled screen portion and transfer it to the other processor's controlled screen region, and vice versa.
