A fixed number of variable-length instructions are stored in each line of an instruction cache. The variable-length instructions are aligned along predetermined boundaries. Since the length of each instruction in the line, and hence the span of memory the instructions occupy, is not known, the address of the next following instruction is calculated and stored with the cache line. Ascertaining the instruction boundaries, aligning the instructions, and calculating the next fetch address are performed in a predecoder prior to placing the instructions in the cache.

A system and method for a secondary water drainage system with street level leak detection positioned between spaced apart prefabricated building panels is disclosed herein. In the space between two adjacent prefabricated building panels, an inner line of caulk is formed from the top to the bottom of the panels. Next, a porous drain strip is positioned adjacent to a first side of the inner line of caulk, also extending vertically from the top to the bottom of the panels. Lastly, an exterior line of caulk if formed adjacent to the porous drain strip extending vertically from the top of the panels to a point just above the bottom of the panels. The porous drain strip is extended through this space formed in the exterior line of caulk and allows the water collected to exit through the same space.

A pipelined processor comprises an instruction cache (iCache), a branch target address cache (BTAC), and processing stages, including a stage to fetch from the iCache and the BTAC. To compensate for the number of cycles needed to fetch a branch target address from the BTAC, the fetch from the BTAC leads the fetch of a branch instruction from the iCache by an amount related to the cycles needed to fetch from the BTAC. Disclosed examples either decrement a write address of the BTAC or increment a fetch address of the BTAC, by an amount essentially corresponding to one less than the cycles needed for a BTAC fetch.

A processor includes a conditional branch instruction prediction mechanism that generates weighted branch prediction values. For weakly weighted predictions, which tend to be less accurate than strongly weighted predictions, the power associating with speculatively filling and subsequently flushing the cache is saved by halting instruction prefetching. Instruction fetching continues when the branch condition is evaluated in the pipeline and the actual next address is known. Alternatively, prefetching may continue out of a cache. To avoid displacing good cache data with instructions prefetched based on a mispredicted branch, prefetching may be halted in response to a weakly weighted prediction in the event of a cache miss.

Systems and methods for downloading and updating software, in which a plurality of manifest files are obtained, each manifest file containing information corresponding to one or more components. Information contained in each manifest file is displayed in a dual-list format, where a first list displays a component name for each component listed in each manifest file, including components installed and not installed on the computer, a second list displays the component name for each component of the first list that is installed on the computer, and the component names in the first list are displayed aligned with the component names in the second list such that the component name of each installed component that appears in the first list is displayed aligned with the component name of the same installed component on the second list.

A computer-based training (CBT) system using versatile resources to support multiple training scenarios in a multi-user environment. The CBT system includes an authoring program module accessible by a lesson designer to create a number of lessons. The CBT system includes one or more runner program modules accessible by lesson takers for running the lessons created with the authoring program module. The CBT system also includes a relational database accessible by the runner program modules and comprises administrative information and information for retrieving desired resources. The versatile resources reduce the memory storage requirements for a CBT system capable of supporting multiple training scenarios in a multi-user network environment. The CBT system realistically simulates multi-mode communication systems and implements progressive mentoring and voice-based progression methodologies.

A dunnage or cargo air bag has incorporated therein a pair of glue or adhesive bonding strips which are located within the immediate vicinity of the inflation valve assembly so as to operatively cooperate with a folded edge portion of the dunnage or cargo air bag and a stitched or sewn edge portion of the dunnage or cargo air bag and thereby effectively surround or circumscribe the inflation valve assembly. In this manner, the plurality of paper plies are able to be effectively secured in a substantially flattened state upon the four sides surrounding the inflation valve assembly whereby the portion of each one of the plurality of paper plies, which effectively forms or defines the inner, annular periphery or rim wall portion of each one of the apertures, holes, or openings through which, for example, the tubular body member of the inflation valve assembly projects outwardly, will not be disposed within the vicinity of the external thread portions of the tubular body member of the inflation valve assembly so as not to effectively interfere with the threaded engagement and secured mounting of the internally threaded closure cap upon the externally threaded tubular body member of the inflation valve assembly.

A hydraulic system for controlling the engagement and disengagement of a friction element includes a source of line pressure, a source of exhaust pressure, a manual valve having a forward state and a reverse state, connected to the exhaust pressure source and line pressure source and including a first outlet and a second outlet, for opening and closing communication between said outlets and said pressure sources in response to changes in the states, a friction element communicating with the line pressure source through the manual valve in the reverse state, and a control valve including a port communicating with the friction element, the control valve producing control pressure at the port when the manual valve is in the forward state.
