Abstract: One embodiment of the present invention provides a system that facilitates deferring execution of instructions with unresolved data dependencies as they are issued for execution in program order. During a normal execution mode, the system issues instructions for execution in program order. Upon encountering an unresolved data dependency during execution of an instruction, the system generates a checkpoint that can subsequently be used to return execution of the program to the point of the instruction. Next, the system executes the instruction and subsequent instructions in an execute-ahead mode, wherein instructions that cannot be executed because of an unresolved data dependency are deferred, and wherein other non-deferred instructions are executed in program order. Upon encountering a store during the execute-ahead mode, the system determines if the store buffer is full. If so, the system prefetches a cache line for the store, and defers execution of the store.

Abstract: One embodiment of the present invention provides a system that dynamically adjusts the aggressiveness of an execute-ahead processor. If a data-dependent stall condition is encountered during program execution, the system enters an execute-ahead mode, wherein instructions that cannot be executed because of the unresolved data dependency are deferred, and other non-deferred instructions are executed in program order. If a non-data-dependent stall condition is encountered during execute-ahead mode, the system enters a scout mode, wherein instructions are speculatively executed to prefetch future loads, but results are not committed to the architectural state of the execute-ahead processor. On the other hand, if an unresolved data dependency is resolved during the execute-ahead mode, enters a deferred mode and executes deferred instructions. During this deferred mode, if some instructions are deferred again, the system determines whether to resume execution in the execute-ahead mode.

Abstract: A processing system that interacts with external devices has a processor, a memory, and a controller. The memory stores templates that provide access protocol information about the external devices. When an external device is to be accessed, the operating system, which is stored in the memory, instructs the processor to perform the access to the external device. The processor puts the information about the external device on the address portion of the system bus where it is received and interpreted by the controller. The controller in turn retrieves the template for the external device as indicated by the information that was received. After retrieving the template, the controller outputs the information, in the manner indicated by the template, on an external interface bus where the external device is also coupled. The external device then responds according to the information that the controller put on the external interface bus.

Abstract: A processor includes a plurality of input ports, memory circuitry for storing data blocks associated with protocol data units (PDUs) and received by the processor at the input ports, and controller circuitry coupled to the memory circuitry. The controller circuitry is operative to discard certain ones of the data blocks received at the input ports in an oversubscription condition in which the received data blocks exceed a designated capacity of the processor. A discarded data block indicator is generated for a given one of the input ports if a data block received at the given input port for a particular PDU is discarded. One or more additional data blocks received at the given input port for the particular PDU are discarded based at least in part on the discarded data block indicator. The oversubscription condition may thereby be overcome in a manner which advantageously minimizes the number of received PDUs that are corrupted through discarded data blocks.

Abstract: An orthogonal data converter for converting the components of a sequential vector component flow to a parallel vector component flow. The data converter has an input rotator configured to rotate corresponding vector components of the sequential vector component flow by a prescribed amount, and a bank of register files configured to store the rotated vector components. The converter also has an output rotator configured to rotate the position of the vector components read from the bank of register files by a prescribed amount. A controller of the converter is operative to control the addressing of the bank of register files and the rotating of the vector components. In this regard, the controller is operative to write the vector components to the bank of register files in a prescribed order and read the vector components in a prescribed order to generate the parallel vector component flow.

The object generator automatically generates code that implements the object based on the description and data types supported by the database server.

Abstract: A solution for translating translatable components in a file containing structured information from a source language to one or more selected destination languages is disclosed. In an embodiment, the translatable components in the original file may be identified by an identifier. Such an identifier may be, for example, a prefix character string, which may be located using a suitable parser. The file and its translatable components may then be separated into a structural base or “skeleton” file, and an “isolated” file containing the translatable components. The translatable components in the isolated file may then be translated from the source language to a selected destination language to form translated components. These translated components in the isolated file may then be merged with the skeletal file to create a new file having substantially the same structure as the original file, but with the translatable components translated into the selected destination language.

Abstract: A method and apparatus are disclosed for transforming information from one semantic environment to another, for example, to facilitate electronic information searches. In one implementation, a SOLx system 1700 includes a Normalization/Translation NorTran Workbench 1702 and a SOLx server 1708. The NorTran Workbench 1702 is used to develop a knowledge base based on information from a source system 1712, to normalize legacy content 1710 according to various rules, and to develop a database 1706 of translated content. During run time, the SOLx server 1708 receives transmissions from the source system 1712, normalizes the transmitted content, accesses the database 1706 of translated content and otherwise translates the normalized content, and reconstructs the transmission to provide substantially real-time transformation of electronic messages. Additionally, content can be classified relative to a taxonomy defining relationships between terms or items so as to facilitate electronic searching or other processing.
