摘要:
A method and system for dividing computer processor registers into sectors and storing frequently used data in the most significant unused sectors. The method includes sector renaming that is performed on each individual sector (i.e., on a sector-by-sector basis) rather than renaming an entire processor register. A register is divided into sectors such that the smallest accessible unit for an instruction in each register can be uniquely addressed and renamed. A register file is divided into sectors so that each process register can be uniquely addressed and renamed. The most significant sectors of the processor registers are used to hold pre-assigned values therein. Data previously loaded into processor register sectors is stored in the most significant sectors of the processor registers for possible future referencing and use. The method also includes establishing a sign-extend memory that includes at least one sign-extend bit in a sector status table.

A method and apparatus for reducing the number of cycles required to implement load instructions in a data processing system having a Central Processing Unit (CPU). The CPU includes a rename register file that can be used in whole or in part for retaining cache lines from previously executed load instructions. The rename register file is then used by subsequent instructions (e.g. load instructions) requiring the data previously loaded therein. Thus, reducing the cycles normally associated with retrieving the data from the cache for the subsequent instructions.

An improved method and system for creating state machines in microcode. State machines are typically defined by a plurality having at least a combinations of current state, next state. Each one of the current states and next states are typically assigned unique values to distinguish them from other current states and next states, respectively. Upon an examination of the binary bit representations for the combinations, certain repetitive patterns become apparent between certain sections of the combinations. These recognized repetitive bit patterns are grouped and represented by linked lists and associated with one another to form the necessary relationship to define the represented combinations. Thus, saving memory and/or storage resources.

An efficient method and system within a data processing system for storing address tags are disclosed, which include a tag directory having a plurality of congruence classes, wherein each congruence class is arranged as a tree-like data structure. A portion of an address tag common to a plurality of address tags is stored in an entry within a node at a first level of a tree-like data structure corresponding to a congruence class of the directory. Portions of the plurality of address tags are stored in a node at a subsequent level of the tree-like data structure, such that all of the plurality of address tags share in common the portion stored in the entry within the node at the first level. Since a portion common to a plurality of address tags is stored only once, the memory space required to store the plurality of address tags is reduced.

Provided is a technology to scan a document for file attachments, generate alternative file names corresponding to a particular attachment, determine whether or not the particular file attachment is the latest version of a file or has a name and/for file path that could he confused with the name and/or path of another file. In the event one or more of the above conditions is met, techniques are also provided to verify that the file attachment is the desired file and, if necessary, to select an alternative file for attachment.

A system for generating multimedia information including audio information, video information, or both is disclosed. The system includes an interface, a text converter, and a first multimedia dictionary. The interface is suitable for receiving a text-based message, such as an email message, from a transmission medium, such as the internet. The text converter is configured to receive the text-based message from the interface. The converter is adapted to decompose the words of the text-based message into their component diphthongs. The first multimedia dictionary receives a diphthong produced by the text converter and produces a set of digitized samples of multimedia information representative of the received diphthong. The system may include a second multimedia dictionary containing its own set of digitized samples. In this embodiment, the system is configured to determine the author of the text-based message and, in response, to select between the first and second multimedia dictionaries.

In one aspect, a method for comparing suppliers includes sending survey questions for receipt by supplier computer systems. Programming instructions are also sent for receipt and execution by the supplier computer systems. The programming instructions are for causing the supplier computer systems to return supplier survey answers to a server. The answers are included in responding documents and are defined in a certain format as data elements included in the responding documents. The data elements are then parsed from the responding documents responsive to predetermined programming instructions and evaluated the data elements responsive to a predetermined set of rules.

Extending the function of a conventional VCR to both do digital recording and to convert analog tape VCR cassette recordings to a digital format without any apparatus modification of the conventional VCR. A portable video recording device comprises a video cassette housing adapted to operatively engage a video cassette recorder, i.e. the VCR requires no modification; the VCR in effect thinks that it is receiving a conventional VCR cassette. The inserted cassette housing comprises a set of read-write heads for operatively engaging an opposing set of read-write heads in the video cassette recorder; disk-drive storage apparatus operatively connected to said cassette read-write heads; and apparatus for converting analog input from the VCR to digital data and storing the data in the disk-drive storage.

Systems, methods and media for content-based search processing are disclosed. In one embodiment, a database is organized according to keywords. Data corresponding to keywords is searched to produce search results within the context of the keywords input by a user. The search results are analyzed to determine features of the data. A feature may be determined by identifying data with common traits. Data is then organized into categories according to the traits. The search results produce information and features of the data that a user may not have thought of but would find useful.

An apparatus and method for converting an instruction and data trace to an executable program are provided. The apparatus and method are used to convert an instruction and data trace to an executable binary program that may then be used on a new computer system such that the simulations and the final computer both have similar run characteristics for a true comparison. The apparatus and method traverse a linear sequence of trace instructions to replace register names with unique labels and propagate these unique labels through the trace instructions. Thereafter, the trace instructions are traversed in a reverse direction to calculate register values based on the value of conditional branch registers. The resulting register values and corresponding memory addresses are then assembled into an executable program.
