Abstract: An apparatus and method are shown for decoding variable length instructions in a processor where a line of variable length instructions from an instruction cache are loaded into an instruction buffer and the start bits indicating the instruction boundaries of the instructions in the line of variable length instructions is loaded into a start bit buffer. A first shift register is loaded with the start bits and shifted in response to a lower program count value which is also used to shift the instruction buffer. A length of a current instruction is obtained by detecting the position of the next instruction boundary in the start bits in the first register. The length of the current instruction is added to the current value of the lower program count value in order to obtain a next sequential value for the lower program count which is loaded into a lower program count register.

Abstract: A memory control circuit in a CD-ROM driving system is provided which controls the writing and reading of data to and from a memory in accordance with a plurality of data operations. The circuit contains a plurality of requesters, a priority level determiner, and a memory control signal generator. The requesters correspond to the plurality of data operations and respectively generate request signals. Furthermore, the requesters respectively generate physical addresses of the memory which are respectively accessed during the data operations. The priority level determiner determines the priority levels of the request signals and outputs a selection signal based on the request signals and the priority levels. Moreover, the selection signal identifies one of the data operations as a selected data operation. The memory control signal generator generates a memory control signal and a memory address which corresponds to one of the physical addresses to be accessed during the selected data operation.

Abstract: A pipeline control system is distributed over the functional units (15, 17, 20, 25) in a processor (10). Decoder logic (12) issues operations, each with an associated tag, to the functional units, with up to n operations allowed to be outstanding. The units execute the operations and report termination information back to the decoder logic, but do not irrevocably change the state of the machine. Based on the termination information, the decoder logic retires normally terminated operations in order. If an operation terminates abnormally, the decoder logic instructs the units to back out of those operations that include and are later than the operation that terminated abnormally.

Abstract: When a data write request is received from an application program, the received data write request is issued to a disk (primary) without waiting next check point, and the data write request is issued to a disk (shadow) after obtaining next check point. When restarting a process from obtained preceding check point, data in the disk (primary) is recovered by data in the disk (shadow). As a result, a delay of I/O request by a check point is decreased, thereby remarkably improving system performance in a normal operation.

Abstract: A system is disclosed that integrates through a single client application access to information resources from a proprietary online service and the Internet. Using a single Web-based client, subscribers enter selections regarding the type of information they would like to retrieve. Relevant information is retrieved from the Internet using the Uniform Resource Locator (URL) addressing scheme of the Internet to locate information on the Internet. Relevant information is retrieved from the online service using extensions to the URL addressing scheme. The extensions map to a proprietary protocol used to obtain information resources from the online service. The client application understands the URLs and extended URLs and manages presentation of the information regardless of the source. Using the present invention, subscribers to online services are no longer required to toggle between a Web browser and service provider communication software in order to view content from both locations.

Abstract: A system and method of configuring VLANs of a multiple port bridging device by merging potentially conflicting VLANs. One or more VLANs are first defined by the user, and equivalent and subset VLANs are merged. The spanning tree procedure is then performed to determine a root identifier and a root port for each VLAN. The root identifier of each VLAN is compared with the other VLANs, and if equal, the root ports of the two VLANs are compared. If the root identifiers are the same and if the root ports are different for any two VLANs, the two VLANs are merged into a new VLAN. To merge two VLANs, all of the ports of both VLANs are combined to define a new VLAN. Preferably, each VLAN is compared with every other VLAN in this manner. The spanning tree procedure is then executed for the new VLAN, which is then compared to the other VLANs in the same manner.

Abstract: Software procedure call overhead, i.e. the memory references or other steps taken to save and restore callee save register values during execution of a called procedure, are reduced by restructuring the procedure code during optimization so that unnecessary or redundant save and restore operations are less likely. The procedure exit block is split into first and second exit blocks, with control flow from the first to the second exit block, and return to the calling procedure from the latter. "Shortcut" control paths are directed to the second exit block, while the new, first exit block is used to post-dominate sections of the code not otherwise amenable to shrink-wrapping techniques. Save and restore operations are wrapped around the non-shortcut code and the new exit block. During execution of the procedure as modified, shortcut paths to the second exit block effectively bypass the first exit block, thereby reducing overhead associated with callee save registers referenced in the non-shortcut path.

Abstract: An improved method and system for accessing the most recent version of a requested data file that has been downloaded into a private network from a source external to the private network. The objects of the method and system are achieved as is now described. A network of computers is defined as private relative to one or more other networks of computers. More than one computer within said defined private network is specified as composing a "common cache." A copy of any data file entering the defined private network from a source external to the defined private network is cached at one or more computers which compose the defined "common cache." In response to a request from a computer within the defined private network for a specific data file which originates from a source external to the defined private network, a determination is made as to whether a copy of the requested specific data file is resident within the defined "common cache.

Abstract: A reorder buffer is configured into multiple lines of storage, wherein a line of storage includes sufficient storage for instructions results regarding a predefined maximum number of concurrently dispatchable instructions. A line of storage is allocated whenever one or more instructions are dispatched. The line of storage remains allocated until each instruction within the line is ready to retire, and then the line is deallocated as the one or more instructions are concurrently retired.
