    摘要： System and method for parallel decoding of character data in run length format to produce data in dot matrix form for presentation to a display device. The data for successive runs is stored in registers and processed in parallel to provide address data for memory devices programmed to deliver predetermined output data patterns in response to the address data.

    摘要： High resolution character generator for producing rows of characters to be scanned on a display medium. Input data defining characters to be printed in ordered rows of text is sorted to provide specifications for the characters which being on each successive scan line. These specifications are stored initially in an input buffer, and specifications for characters which have been partially printed in a previous scan line are stored in an active character buffer. For each scan line, the character specifications are read first from the active character buffer and then from the input buffer until an end of line specifier is reached. For each character specification received, a font memory containing data defining the characters is cycled. The data from the font memory is decoded and presented to the display medium on a line by line basis.

    摘要： In a computerized method, a computer program is analyzed while the program is interpreted. The program is expressed in a first memory as input values and functions. Some of the input values are complex values which can have a plurality of component values. Each function operates on combinations of the input values and the functions of the program. The program is interpreted in a processor connected to the first memory. The processor is also connected to a second memory to store result values produced during the interpretation. Selected input values, components of the complex values, and functions are named only if the selected values, components, and functions are necessary to produce a selected result value. For each function of the program, the function which is interpreted, the input values on which the function depends, and the result value produced by the function during interpretation, are recorded in the second memory to dynamically perform a precise dependency analysis of the program.

    摘要： A technique to facilitate decryption processing of information packets transmitted over a communication network after encryption in accordance with a specific network protocol, the details of which may be subject to later change as standards are developed or modified. Programmable registers are used in the decryption process to hold information for identifying an incoming information packet as being subject to the specific protocol and requiring decryption, and identifying a starting location of a data field to be decrypted. Specifically one programmable register contains a first offset locating an identifier field in the packet, in which a cryptographic identifier will be found if the packet is one conforming to the protocol; another programmable register contains a cryptographic identifier value that will be found in the identifier field if decryption is to be performed, and a third programmable register contains a second offset to locate the beginning of a data field to be decrypted.

    摘要： An architecture for protecting premium content in a nonsecure computer environment executes only a small number of code modules in a secure memory. The modules are arranged in a hierarchy of trust, where a module names other modules that it is willing to trust, and those modules in turn name other modules that they are willing to trust. A secure loader loads a security manager that oversees a number of content-providing modules for manipulating the content. A memory manager assigns permissions to various pages of the secure memory. The memory has rings of different security. The security model can be extended to program modules and other devices on the computer's bus, such as DMA controllers and peripherals.

    摘要： A user interface allows a user to input handwritten, key-press, and spoken text in a seamless, synchronized manner. A text input panel accepts soft keyboard presses and handwritten words, characters, and gestures. A text recognizer/synchronizer integrates textual input from various sources while recognizing and preserving the order in which a user entered text via the soft keyboard, via handwriting, and/or by speaking. Synchronized text may be displayed in a stage area of the text input panel before being passed to an operating system message router and/or an application program. While in handwriting recognition mode, various permutations and combinations of a word recognition area, a character recognition area, and a keybar/keypad may optionally be displayed.

    摘要： Curtained operation provides trusted execution of code and secrecy of data in a secure memory. Curtained code can only be executed from within certain address ranges of a curtained memory region secure against access by code from without the region. Code entry points are restricted, and atomic execution is assured. The memory is organized into multiple hierarchically curtained rings, and peer subrings are denied access to each other as well as to more secure rings.
